[PATCH v7 00/13] Implement Wa_14021768792 to bypass m_n ratio limit

[Suraj Kandpal]

For Platforms that support higher link rates, there is a limitation on
Link M /Link N ratio.
If the CEILING( Link M / Link N ) ratio is greater than 10.0, then
hardware cannot support the given resolution / refresh rate at the given
configuration.
For BMG Wa_14021768792 helps to bypass this limitation and allows it to
support the ratio till 15.0.

This series adds the missing restrictions for earlier platforms and adds
the Wa_14021768792 for BMG as per Bspec:49266

[PATCH v7 01/13] drm/i915/display: Add helper to compute link M/N ratio for reuse

[Suraj Kandpal]

From: Ankit Nautiyal <ankit.k.nautiyal@intel.com>

Introduce intel_display_compute_link_m_n() to compute the link M/N ratio
from the pixel clock and the link symbol clock. This logic was
previously embedded within intel_link_compute_m_n().
The new helper allows reuse of link M/N computation in other contexts
without requiring the full data M/N calculation and will be used in
later commits.

No functional changes intended.

v2:
- Rename function (Jani)
- The link symbol clock is passed in rather than derived here, so that the
DP specific conversion from the link rate stays with the caller. (Jani)

[PATCH v7 02/13] drm/i915/dp: Limit M/N ratio for DP

[Suraj Kandpal]

The hardware cannot support DisplayPort configurations where the
ceiling of the Link M/Link N ratio exceeds the limit the transcoder's
timing generator DDA can track. This limitation has always existed, but
it typically wasn't encountered without the use of joiners and DSC.
With higher resolutions and combinations involving joiners and DSC,
this constraint can now be hit in certain scenarios.

Restrict the link configurations to those satisfying the constraint
while computing the link config limits, so that the SST and the MST
paths both get it, and so that a mode which no link rate can support
fails early rather than deep inside link config selection.

Also prune such modes in mode_valid. Note the ratio is the pixel clock
over the link symbol clock, and the symbol clock is not monotonic in the
link rate: it is the rate divided by 32 for 128b/132b but only by 10 for
8b/10b, so e.g. HBR3 has a higher symbol clock than UHBR20. There is
therefore no single best link rate to evaluate against, and mode_valid
walks the link configurations instead, only rejecting the mode if none
of them can satisfy the ratio.

For MSO, intel_dp_compute_config() divides adjusted_mode->crtc_clock by
the MSO link count before computing the link M/N. The limits and
mode_valid are evaluated before that, so divide the pixel clock by the
link count there as well, otherwise the check would be too strict by
that factor. The joiner needs no such handling, as
intel_joiner_adjust_timings() only rewrites the pipe mode and leaves the
adjusted mode the link M/N is derived from untouched.

Note: MST goes through intel_dp_compute_config_limits() as well, so its
compute config is already covered here. Only pruning the modes in the
MST mode_valid is left, which is added in a subsequent commit.

v2:
-Move the M/N ratio check to the link rate configuration phase instead
of during M/N computation. (Ville)
-Prune modes that cannot be supported even with highest link rate due to
M/N ratio restriction.
v3:
-Rebase on the link caps iterator based link config selection.
-Set the constraint up in intel_dp_compute_config_limits() by narrowing
the link config filter, and fail there if no config qualifies, instead
of skipping configs while iterating them. (Imre)
-Use a limit of 4 on DG2. (Wa_14014191401)
-Walk the link configurations in mode_valid rather than evaluating the
ratio at the highest link rate, which is not the best case for it.
v4:
-Add iterator for all dp configs in intel_dp_mode_valid_m_n() so
that we do not prune any mode that could have been supported (Sashiko)
v5:
-Drop "SST" from the subject and fix the note, MST compute is already
covered by the shared limits, only the MST mode_valid is left. (Mitul)
-Add the Bspec reference. (Mitul)
-Drop the link_n check, compute_m_n() fixes N at 0x80000 and only halves
it, so it cannot be 0. (Mitul)
-Fold in the MSO adjusted pixel clock from the M/N ratio check commit, so
this commit is correct on its own. (Mitul)
-Add intel_dp_link_m_n_ratio(), so that the M/N ratio check can share
it. (Mitul)

[Severity: Medium]
Does calling intel_dp_compute_m_n_ratio_limits() after the
(is_mst || intel_dp->use_max_params) block and before
intel_dp_test_compute_config() in intel_dp_compute_config_limits() cause two
filtering regressions?

First, in drivers/gpu/drm/i915/display/intel_dp.c:
intel_dp_compute_config_limits() narrows limits->link_config_filter to a
single max_config before intel_dp_compute_m_n_ratio_limits() runs:

	if (is_mst || intel_dp->use_max_params) {
		...
		if (!intel_dp_get_connector_max_link_config(connector, limits, &max_config))
			return false;

		if (!intel_dp_link_caps_filter_add(link_caps, &new_filter, &max_config))
			return false;

		limits->link_config_filter = new_filter;
	}

	if (!intel_dp_compute_m_n_ratio_limits(intel_dp, conn_state, crtc_state, limits))
		return false;

Because 128b/132b symbol clocks (rate * 10 / 32) are lower than 8b/10b symbol
clocks (rate * 10 / 10), max_config can pick a UHBR rate such as UHBR10
(312.5 MHz symbol clock) or UHBR20 (625 MHz symbol clock) that exceeds the
M/N ratio limit for a high pixel clock mode, even when a lower link rate like
HBR3 (810 MHz symbol clock) or HBR2 (540 MHz symbol clock) satisfies the M/N
ratio and passed intel_dp_mode_valid_m_n(). Since
intel_dp_compute_m_n_ratio_limits() only iterates over
limits->link_config_filter, won't it reject the modeset instead of allowing
intel_dp_get_connector_max_link_config() to select the highest M/N-compatible
configuration?

Second, intel_dp_test_compute_config() is called right after
intel_dp_compute_m_n_ratio_limits(). When intel_dp->compliance.test_type is
DP_TEST_LINK_TRAINING, intel_dp_test_compute_config() ->
set_filter_for_link_params() -> set_filter_for_link_config() in
drivers/gpu/drm/i915/display/intel_dp_test.c overwrites
limits->link_config_filter with a fresh filter:

static bool set_filter_for_link_config(struct intel_connector *connector,
				       struct intel_dp_link_caps *link_caps,
				       const struct intel_dp_link_config *link_params,
				       struct link_config_limits *limits)
{
	struct intel_dp_link_caps_filter new_filter = INTEL_DP_LINK_CAPS_FILTER_NONE;

	if (!intel_dp_link_caps_filter_add(link_caps, &new_filter, link_params))
		return false;

	limits->link_config_filter = new_filter;

	return true;
}

Because intel_dp_link_caps_filter_add() checks get_allowed_config_filter()
rather than limits->link_config_filter, won't this discard the M/N ratio
filter applied by intel_dp_compute_m_n_ratio_limits() and allow an
M/N-invalid compliance link configuration?

Should intel_dp_compute_m_n_ratio_limits() be called before the
(is_mst || intel_dp->use_max_params) block, or after
intel_dp_test_compute_config() while also filtering before
intel_dp_get_connector_max_link_config()?

[PATCH v7 03/13] drm/i915/display_wa: Add support for Wa_14014191401

[Suraj Kandpal]

The DG2 transcoder timing generator DDA only supports a Link M/N ratio
of up to 4. The Link M/N ratio limit uses a bare platform check for it.

Add Wa_14014191401 for DG2 and use it for the limit instead.

[PATCH v7 04/13] drm/i915/dp_mst: Limit M/N ratio for MST

[Suraj Kandpal]

From: Ankit Nautiyal <ankit.k.nautiyal@intel.com>

The hardware does not support DisplayPort configurations where the
ceiling of the Link M/Link N ratio exceeds the limit. Enforce this
constraint for MST as well.

The compute config path needs no change: MST goes through
intel_dp_compute_config_limits() too, so the link config filter set up
there already excludes the configurations violating the ratio limit, and
MST fails there if none is left.

What is still missing is pruning such modes, so add the check to
mst_connector_mode_valid_ctx(), reusing the helper the SST mode_valid
uses. It walks the link configurations and only rejects the mode if none
of them can satisfy the ratio, rather than evaluating it at a single
link rate.

v2:
-Drop the checks in the MST link config helpers, redundant now that the
constraint is applied while computing the link config limits. (Imre)
-Share the mode_valid helper with SST instead of evaluating the ratio at
one link rate, since the link symbol clock is not monotonic in the link
rate and there is no single best case configuration.
v3:
-Now that intel_dp_mode_valid_m_n checks for all configs just call
that (Sashiko)

drm/i915/dp_mst: Limit M/N ratio for MST

This commit adds a Link M/Link N ratio check to mst_connector_mode_valid_ctx()
using intel_dp_mode_valid_m_n() to prune display modes that exceed the
hardware M/N ratio limit on MST connectors.

[Severity: Medium]
Does calling intel_dp_mode_valid_m_n() here match the link configuration
constraints enforced during MST modeset in intel_dp_compute_config_limits()?

In drivers/gpu/drm/i915/display/intel_dp_mst.c, mst_connector_mode_valid_ctx()
evaluates bandwidth and DSC against max_bw_config, whereas
intel_dp_mode_valid_m_n() in drivers/gpu/drm/i915/display/intel_dp.c iterates
over all configurations in INTEL_DP_LINK_CAPS_FILTER_ALL:

drivers/gpu/drm/i915/display/intel_dp.c:intel_dp_mode_valid_m_n() {
	intel_dp_link_caps_iter_start(&iter, intel_dp->link.caps, order,
				      INTEL_DP_LINK_CAPS_FILTER_ALL);
	for_each_dp_link_config(&iter, &link_config) {
		if (intel_dp_can_support_m_n(display, m_n_pixel_clock,
					     link_config.rate)) {
			found = true;

			break;
		}
	}
}

On a UHBR-capable MST topology (for example UHBR10 with a 312.5 MHz symbol
clock, or UHBR13.5 with a 421.875 MHz symbol clock), intel_dp->link.caps also
includes 8b/10b rates such as HBR3 (810 MHz symbol clock). Because HBR3 has a
higher link symbol clock than UHBR10 or UHBR13.5, intel_dp_mode_valid_m_n()
will see that HBR3 satisfies intel_dp_can_support_m_n() and return true even
when max_bw_config violates the M/N ratio limit.

However, during modeset via
mst_stream_compute_config() -> mst_stream_compute_link_for_joined_pipes() ->
mst_stream_compute_config_limits() -> intel_dp_compute_config_limits(),
the MST path narrows limits->link_config_filter to the single highest-BW
max_config before intel_dp_compute_m_n_ratio_limits() is called:

drivers/gpu/drm/i915/display/intel_dp.c:intel_dp_compute_config_limits() {
	if (is_mst || intel_dp->use_max_params) {
		struct intel_dp_link_caps_filter new_filter = INTEL_DP_LINK_CAPS_FILTER_NONE;
		struct intel_dp_link_config max_config;
		...
		if (!intel_dp_get_connector_max_link_config(connector, limits, &max_config))
			return false;

		if (!intel_dp_link_caps_filter_add(link_caps, &new_filter, &max_config))
			return false;

		limits->link_config_filter = new_filter;
	}

	if (!intel_dp_compute_m_n_ratio_limits(intel_dp, conn_state, crtc_state, limits))
		return false;
}

As a result, intel_dp_compute_m_n_ratio_limits() only checks max_config for
MST and rejects the modeset if max_config violates the M/N ratio limit.

Should mst_connector_mode_valid_ctx() check intel_dp_can_support_m_n() against
max_link_clock (matching the rest of mst_connector_mode_valid_ctx() and the
current MST max_config selection), or should intel_dp_compute_m_n_ratio_limits()
filter limits->link_config_filter before intel_dp_get_connector_max_link_config()
picks max_config?

[PATCH v7 05/13] drm/i915/dp: Add M/N ratio check for DP link config

[Suraj Kandpal]

From: Ankit Nautiyal <ankit.k.nautiyal@intel.com>

Introduce intel_dp_check_m_n_ratio() to validate the computed link M/N
ratio against the maximum allowed value, and log it if the ratio exceeds
the limit.

The link config limits computed in the previous commits only restrict
the configurations that may be selected; this catches anything that
still slips through.

Log it rather than warn about it: the link config filter already
excludes the configurations violating the limit, so the only way to get
here is with link parameters forced through debugfs, which are applied
after that filter. A user triggerable drm_WARN() with its backtrace
would be out of proportion for that.

For MST the check goes after the bpp loop rather than inside it. The
link M/N is computed from the pixel clock and the link symbol clock, so
it does not depend on the bpp being tried and the result is the same on
every iteration.

v2:
-Use the platform specific ratio limit. (Wa_14014191401)
-Use the MSO adjusted pixel clock when predicting the ratio, matching
what the link M/N is actually computed from. (Imre)
-Drop the check from ilk_fdi_compute_config(): it was passing dp_m_n
rather than the fdi_m_n it had just computed, and an FDI link cannot get
anywhere near the ratio limit anyway.
v3:
-Check the ratio once after the MST bpp loop instead of on every
iteration, the result does not depend on the bpp. (Sashiko)
-Log instead of warning, since the link config filter already excludes
these configurations and only forced link parameters can reach it.
(Sashiko)
v4:
-Move the MSO adjusted pixel clock to the commit adding the prediction,
so that one is correct on its own. (Mitul)
-Reuse intel_dp_link_m_n_ratio() instead of open coding the ratio.
(Mitul)
-Drop the m_n and link_n checks, neither can be NULL or 0. Make the
parameters const and move it next to intel_dp_can_support_m_n().
(Mitul)
-Drop the check on dp_m2_n2, the dp_m_n one already covers it. (Mitul)

[PATCH v7 06/13] drm/i915/display: Add bits for link_n_extended for DISPLAY >= 14

[Suraj Kandpal]

From: Ankit Nautiyal <ankit.k.nautiyal@intel.com>

LINK_N register has bits 31:24 for extended link N value used for
HDMI2.1 and for an alternate mode of operation of DP TG DDA.

Add support for these extra bits.

For displays with version 14 or higher, PIPE_LINK_N1_EXTENDED_MASK
(bits 31:24) is used to handle the extended link N bits. For older
platforms, DATA_LINK_M_N_MASK (bits 23:0) is used to handle the
standard link N bits. This distinction ensures clarity and maintains
the semantics for platforms that support the extended bits. In
subsequent changes the logic is updated to conditionally apply the
extended link N bits.

v2: Drop extra link_n_ext member. (Jani)
v3: Avoid link_n_ext in set_m_n helper. (Jani)
v4: Rebase, and update commit message.
v5: Drop a stale changelog entry, the DISPLAY_VER split here is
    intentional. (Sashiko)

[PATCH v7 07/13] drm/i915/display_wa: Add support for Wa_14021768792

[Suraj Kandpal]

From: Ankit Nautiyal <ankit.k.nautiyal@intel.com>

Some BMG ultrajoiner configurations require support for Link M/N ratios
between 10.0 and 15.0. This range is not natively supported and requires
a workaround.

Wa_14021768792 enables this support by utilizing HDMI_EMP_DATA,
CHICKEN_TRANS and the extended bits in the LINK_N register.

Add the necessary logic to enable the workaround on applicable platforms.
The underlying mechanism comes from the display C0,
so it is gated on display stepping C0 and later.

v2:
-Don't include i915_drv.h and don't use struct drm_i915_private under
display/. Use display->platform.battlemage, which names the affected
platform directly, instead of IS_DGFX() combined with a display version
check. (Jani)
-Rebase on the reworked display WA framework, where the condition goes
directly into the __intel_display_wa() switch.

[PATCH v7 08/13] drm/i915/display: Add bits for Wa_14021768792 for linkm/n ratio > 10

[Suraj Kandpal]

From: Ankit Nautiyal <ankit.k.nautiyal@intel.com>

To support a Link M/N ratio between 10.0 and 15.0, for some BMG
ultrajoiner cases we need Wa_14021768792.

To bypass the hardware limitation within the Timing Generator DDA
(TGDDA), we need to program the LINKM and LINKN registers as defined in
the WA. Along with this we also need the relevant bits in HDMI_EMP_DATA
and CHICKEN_TRANS.

Add the bits for the WA and a new member 'bypass_m_n_ratio_limit' to
track if we need to bypass the Link M/N ratio limit in the
intel_link_m_n structure.

Per Bspec the extended LINK_N field is two nibbles: bits 27:24 hold
INT(Link M / Link N) and bits 31:28 hold CEIL(Link M / Link N).

The workaround is limited to transcoder A. Check the transcoder rather
than the pipe: for a single pipe the two are the same, but the joiner
secondaries read the M/N back through the primary's transcoder, so a
pipe check would have them report the workaround as not applied while
their state, copied from the primary, has it applied.

CHICKEN_TRANS and HDMI_EMP_DATA are programmed before LINK_N, since
writing LINK_N arms the double buffered update of the M/N registers, and
all of the programming has to be done before the transcoder is enabled.
Both are also explicitly cleared when the mechanism is not in use, so
that state cannot leak from a previous modeset.

v2:
-Drop the drm_WARN_ON() on the extended LINK_N field in intel_get_m_n():
it is derived from Link M and Link N, so the state checker comparison of
those and of bypass_m_n_ratio_limit already covers it. (Sashiko)
-Compare bypass_m_n_ratio_limit unconditionally, so that a change to it
forces a full modeset instead of being applied during a seamless M/N
fastset. (Sashiko)
v3:
-Check for transcoder A instead of pipe A, so that the joiner secondaries
read the flag back the same as the primary. (Mitul)
-Drop bypass_m_n_ratio_limit from intel_compare_link_m_n(), the
unconditional PIPE_CONF_CHECK_BOOL() already compares it. (Mitul)
-Print bypass_m_n_ratio_limit in the crtc state dump. (Mitul)
v4:
-Move the state checker comparison and the state dump of
bypass_m_n_ratio_limit to separate commits. (Mitul)

> 
> To support a Link M/N ratio between 10.0 and 15.0, for some BMG ultrajoiner
> cases we need Wa_14021768792.
> 
> To bypass the hardware limitation within the Timing Generator DDA (TGDDA),
> we need to program the LINKM and LINKN registers as defined in the WA.
> Along with this we also need the relevant bits in HDMI_EMP_DATA and
> CHICKEN_TRANS.
> 
> Add the bits for the WA and a new member 'bypass_m_n_ratio_limit' to track
> if we need to bypass the Link M/N ratio limit in the intel_link_m_n structure.
> 
> Per Bspec the extended LINK_N field is two nibbles: bits 27:24 hold INT(Link
> M / Link N) and bits 31:28 hold CEIL(Link M / Link N).
> 
> The workaround is limited to transcoder A. Check the transcoder rather than
> the pipe: for a single pipe the two are the same, but the joiner secondaries
> read the M/N back through the primary's transcoder, so a pipe check would
> have them report the workaround as not applied while their state, copied
> from the primary, has it applied.
> 
> CHICKEN_TRANS and HDMI_EMP_DATA are programmed before LINK_N,
> since writing LINK_N arms the double buffered update of the M/N registers,
> and all of the programming has to be done before the transcoder is enabled.
> Both are also explicitly cleared when the mechanism is not in use, so that
> state cannot leak from a previous modeset.
> 
> v2:
> -Drop the drm_WARN_ON() on the extended LINK_N field in intel_get_m_n():
> it is derived from Link M and Link N, so the state checker comparison of those
> and of bypass_m_n_ratio_limit already covers it. (Sashiko) -Compare
> bypass_m_n_ratio_limit unconditionally, so that a change to it forces a full
> modeset instead of being applied during a seamless M/N fastset. (Sashiko)
> v3:
> -Check for transcoder A instead of pipe A, so that the joiner secondaries read
> the flag back the same as the primary. (Mitul) -Drop bypass_m_n_ratio_limit
> from intel_compare_link_m_n(), the unconditional
> PIPE_CONF_CHECK_BOOL() already compares it. (Mitul) -Print
> bypass_m_n_ratio_limit in the crtc state dump. (Mitul)
> v4:
> -Move the state checker comparison and the state dump of
> bypass_m_n_ratio_limit to separate commits. (Mitul)

This commit still combines register definitions, WA programming, the bypass helper and readback.
For reviewability, could it be split into: (1) register definitions, (2) the bypass_m_n_ratio_limit member
plus write-side programming, (3) readback together with the state checker compare
(fold `drm/i915/display: Compare bypass_m_n_ratio_limit in the state checker` into it),
with the dump staying separate ?

I'd keep the compare after the readout rather than before, so it doesn't land without anything that sets the flag.

Not a blocker; the current order is bisect-safe.

Optional,
for reviewability: 548e544158f8f could be split into
(A) the register definitions,
(B) the bypass_m_n_ratio_limit member plus the write side (bmg_get_link_n_ext(), intel_set_m_n(), bmg_enhanced_tgdda_write()), and
(C) intel_display_can_bypass_m_n_limit() plus readback, with "Compare bypass_m_n_ratio_limit in the state checker" folded into (C).

Each step builds and is bisect-safe since nothing sets the flag until the compute patches. Fine to keep as is if you prefer.

[PATCH v7 09/13] drm/i915/display: Compare bypass_m_n_ratio_limit in the state checker

[Suraj Kandpal]

Compare bypass_m_n_ratio_limit in intel_pipe_config_compare(), so that a
mismatch between the computed and the read back state of
Wa_14021768792 is caught.
Only bypass_m_n_ratio_limit is compared, not the ratio integer and
fraction themselves. That is deliberate: both are derived from Link M
and Link N, which are compared already, so the thing worth verifying is
whether the workaround ended up being applied or not.
Unlike the rest of the M/N registers, CHICKEN_TRANS and HDMI_EMP_DATA
are not double buffered, so the flag has to be compared outside the
fastset exemption that PIPE_CONF_CHECK_M_N() has for update_m_n.
Otherwise a seamless M/N update could switch the DDA out of the
workaround on a live transcoder, with the Link M/N values only following
at the next MSA.

[PATCH v7 11/13] drm/i915/display: Implement Wa_14021768792 for BMG DP for link_m/n ratio > 10

[Suraj Kandpal]

From: Ankit Nautiyal <ankit.k.nautiyal@intel.com>

Handle the bypass logic for the M/N ratio limit for DP.
Calculate the M/N ratio, check if it can bypass the limit, and set the
appropriate flags for the workaround.

v2:
-Restrict the workaround to 128b/132b links.
-Clear bypass_m_n_ratio_limit on entry, so a rejected link rate cannot
leave it set for the rate that gets used. (Sashiko)
v3:
-Rebase on the reworked M/N ratio check, which no longer checks m_n and
link_n. m_n is no longer const, as the flag is set through it. (Mitul)
-Pass the cpu transcoder to intel_display_can_bypass_m_n_limit() instead
of the pipe. (Mitul)

[PATCH v7 12/13] drm/i915/dp: Extend intel_dp_can_support_m_n() for BMG M/N bypass

[Suraj Kandpal]

From: Ankit Nautiyal <ankit.k.nautiyal@intel.com>

On BMG platforms, the standard M/N ratio limit of 10 can be bypassed
under specific conditions, as permitted by hardware capabilities.

Modify the helper intel_dp_can_support_m_n() to account for this by
checking whether the platform supports bypassing the limit. The
workaround is only intended for 128b/132b links, so restrict it to
those.

During the mode_valid phase, the check assumes that TRANSCODER_A will be
used, to allow the mode where the M/N ratio is within the limits for the
workaround.

v2:
-Keep the helper static: the MST mode_valid now goes through the shared
intel_dp_mode_valid_m_n() rather than calling it directly, so it no
longer needs to be exported.
v3:
-Use the cpu transcoder instead of the pipe, following the change to
intel_display_can_bypass_m_n_limit(). (Mitul)

The same bypass conditions (UHBR + intel_display_can_bypass_m_n_limit) are duplicated
in intel_dp_check_m_n_ratio. Please move them into one helper so the prediction and
the decision can't drift apart.

Bypass-capable configs now land in the same filter as native ones.
SST walks rates in ascending order, so UHBR10 with the WA (ratio 10-15)
gets picked before UHBR13.5, which may satisfy the ratio natively.
Could we keep the WA as a last resort: build the native filter first,
and add the bypass-capable configs only if none qualify?

One suggestion, not mandatory,

If possible,

This makes the bypass branch added in "Implement Wa_14021768792 for BMG DP..." reachable.
Please put this patch first or squash the two, so the WA arrives as one working change.

On using the WA as a last resort: native first breaks the WA in practice.
Whenever UHBR10 needs the WA (ratio 10-15, ~3.1-4.7 GHz), HBR2/HBR3 pass the
ratio natively thanks to their higher symbol clock, so the native set is
never empty and the WA configs never get added. Since the filter is built
before the BW check, a mode that only fits at UHBR10 would then fail compute.
Doing it right would need a second compute pass, and I don't think it buys
anything: a ratio above 10 needs ultrajoiner, which already disables seamless
M/N, there's no DRRS on BMG, and preferring the lower link rate is the
existing SST policy. Bspec only requires the WA to be used when the ratio
exceeds the limit, which is the case for the config we pick

With this patch first, ratios above 10 get
through the filter before anything sets the flag, so a bisect could land on a
config programmed without the WA. The bypass branch is also reachable before
this patch with forced link params. And I'd rather keep the two separate
than squash them.
