This series reworks i915's internal handling of slice/subslice/EU (SSEU)
data to represent platforms like Xe_HP in a more natural manner and to
prepare for future platforms where the masks will need to grow in size.
One key idea of this series is that although we have a fixed ABI to
convey SSEU data to userspace (i.e., multiple u8[] arrays with data
stored at different strides), we don't need to use this cumbersome
format for the driver's own internal storage. As long as we can convert
into the uapi form properly when responding to the I915_QUERY ioctl,
it's preferable to use an internal storage format that's easier for the
driver to work with.
Another key point here is that we're reaching the point where subslice
(DSS) masks will soon not fit within simple u32/u64 integer values.
Xe_HP SDV and DG2 platforms today have subslice (DSS) masks that are 32
bits, which maxes out the current storage of a u32. With PVC the masks
are represented by a pair of 32-bit registers, requiring a bump up to at
least 64-bits of storage internally. We could switch to u64 for that in
the short term, but since we already know that upcoming architectures
intend to provide DSS fuse bits via three or more registers it's best to
switch to a representation that's more future-proof but still easy to
work with in the driver code. To accomodate this, we start storing our
subslice mask for Xe_HP and beyond in a new typedef that can be
processed by the linux/bitmap.h operations.
Finally, since no userspace for Xe_HP or beyond is using the legacy
I915_GETPARAM ioctl lookups for I915_PARAM_SLICE_MASK and
I915_PARAM_SUBSLICE_MASK (since they've migrated to the more flexible
I915_QUERY ioctl that can return more than a simple u32 value), we take
the opportunity to officially drop support for those GETPARAM lookups on
modern platforms. Maintaining support for these GETPARAM lookups don't
make sense for a number of reasons:
* Traditional slices no longer exist, and newer ideas like gslices,
cslices, mslices, etc. aren't something userspace needs to query
since it can be inferred from other information.
* The GETPARAM ioctl doesn't have a way to distinguish between geometry
subslice masks and compute subslice masks, which are distinct on
Xe_HP and beyond.
* The I915_GETPARAM ioctl is limited to returning a 32-bit value, so
when subslice masks begin to exceed 32-bits (on PVC), it simply can't
return the entire mask.
* The GETPARAM ioctl doesn't have a way to give sensible information
for multi-tile devices.
v2:
- Switch to union of hsw/xehp formats to keep the representation in a
natural format for different types of hardware.
- Avoid accessing internals of intel_sseu_ss_mask_t directly outside of
intel_sseu.[ch].
- Include PVC SSEU which needs the larger SS mask storage enabled by
this series.
v3:
- Correct a BIT(s) typo that should have been BIT(ss), causing
incorrect handling on gen9 platforms.
v4:
- Eliminate sseu->{ss,eu}_stride fields and just calculate the proper
value in the UAPI code that needs them.
- Handle unwanted ~u8 sign extension at the callsite instead of inside
sseu_set_eus.
- Use BITMAP_BITS() macro rather than passing I915_MAX_SS_FUSE_BITS
around directly to bitmap operations.
- Improved debugfs / dmesg reporting for Xe_HP dumps
- Various assertion check improvements.

The subslice mask lookup is even more problematic; given the distinct masks for geometry vs compute purposes, the combined mask returned here is likely not what userspace would want to act upon anyway. The value is also limited to 32-bits by the nature of the GETPARAM ioctl which is sufficient for the initial Xe_HP platforms, but is unable to convey the larger masks that will be needed on other upcoming platforms.

Since the hardware design changed significantly with Xe_HP, we'll use a union to choose between the old "hsw-style" subslice masks or the newer xehp mask. HSW-style masks will be stored in an array of u8's, indexed by slice (there's never more than 6 subslices per slice on older platforms). For Xe_HP and beyond where slices no longer exist, we only need a single bitmask. However we already know that this mask is eventually going to grow too large for a simple u64 to hold, so we'll represent it in a manner that can be operated on by the utilities in linux/bitmap.h. v2: - Fix typo: BIT(s) -> BIT(ss) in gen9_sseu_device_status() v3: - Eliminate sseu->ss_stride and just calculate the stride while specifically handling uapi. (Tvrtko) - Use BITMAP_BITS() macro to refer to size of masks rather than passing I915_MAX_SS_FUSE_BITS directly. (Tvrtko) - Report compute/geometry DSS masks separately when dumping Xe_HP SSEU info. (Tvrtko) - Restore dropped range checks to intel_sseu_has_subslice().

It works without it because union will be larger, same size as bitmap. (Or hm will it on 32-bit builds?) If so this tweak applies throughout the patch. Or append the .xehp union member name in the macro itself? If renamed to i915 specific name that would work I think.

* [Intel-gfx] [PATCH v5 5/6] drm/i915/sseu: Disassociate internal subslice mask representation from uapi 2022-05-20 23:04 ` [Intel-gfx] [PATCH v4 5/6] drm/i915/sseu: Disassociate internal subslice mask representation from uapi Matt Roper 2022-05-23 7:59 ` Tvrtko Ursulin @ 2022-05-23 20:45 ` Matt Roper 2022-06-01 8:18 ` Balasubramani Vivekanandan 1 sibling, 1 reply; 25+ messages in thread From: Matt Roper @ 2022-05-23 20:45 UTC (permalink / raw) To: intel-gfx; +Cc: dri-devel As with EU masks, it's easier to store subslice/DSS masks internally in a format that's more natural for the driver to work with, and then only covert into the u8[] uapi form when the query ioctl is invoked. Since the hardware design changed significantly with Xe_HP, we'll use a union to choose between the old "hsw-style" subslice masks or the newer xehp mask. HSW-style masks will be stored in an array of u8's, indexed by slice (there's never more than 6 subslices per slice on older platforms). For Xe_HP and beyond where slices no longer exist, we only need a single bitmask. However we already know that this mask is eventually going to grow too large for a simple u64 to hold, so we'll represent it in a manner that can be operated on by the utilities in linux/bitmap.h. v2: - Fix typo: BIT(s) -> BIT(ss) in gen9_sseu_device_status() v3: - Eliminate sseu->ss_stride and just calculate the stride while specifically handling uapi. (Tvrtko) - Use BITMAP_BITS() macro to refer to size of masks rather than passing I915_MAX_SS_FUSE_BITS directly. (Tvrtko) - Report compute/geometry DSS masks separately when dumping Xe_HP SSEU info. (Tvrtko) - Restore dropped range checks to intel_sseu_has_subslice(). (Tvrtko) v4: - Make the bitmap size macro check the size of the .xehp field rather than the containing union. (Tvrtko) - Don't add GEM_BUG_ON() intel_sseu_has_subslice()'s check for whether slice or subslice ID exceed sseu->max_[sub]slices; various loops in the driver are expected to exceed these, so we should just silently return 'false.'

* [Intel-gfx] [PATCH v5 0/6] i915: SSEU handling updates
@ 2022-06-01 15:07 Matt Roper
2022-06-01 15:07 ` [Intel-gfx] [PATCH v5 5/6] drm/i915/sseu: Disassociate internal subslice mask representation from uapi Matt Roper
0 siblings, 1 reply; 25+ messages in thread
From: Matt Roper @ 2022-06-01 15:07 UTC (permalink / raw)
To: intel-gfx; +Cc: dri-devel
This series reworks i915's internal handling of slice/subslice/EU (SSEU)
data to represent platforms like Xe_HP in a more natural manner and to
prepare for future platforms where the masks will need to grow in size.
One key idea of this series is that although we have a fixed ABI to
convey SSEU data to userspace (i.e., multiple u8[] arrays with data
stored at different strides), we don't need to use this cumbersome
format for the driver's own internal storage. As long as we can convert
into the uapi form properly when responding to the I915_QUERY ioctl,
it's preferable to use an internal storage format that's easier for the
driver to work with.
Another key point here is that we're reaching the point where subslice
(DSS) masks will soon not fit within simple u32/u64 integer values.
Xe_HP SDV and DG2 platforms today have subslice (DSS) masks that are 32
bits, which maxes out the current storage of a u32. With PVC the masks
are represented by a pair of 32-bit registers, requiring a bump up to at
least 64-bits of storage internally. We could switch to u64 for that in
the short term, but since we already know that upcoming architectures
intend to provide DSS fuse bits via three or more registers it's best to
switch to a representation that's more future-proof but still easy to
work with in the driver code. To accomodate this, we start storing our
subslice mask for Xe_HP and beyond in a new typedef that can be
processed by the linux/bitmap.h operations.
Finally, since no userspace for Xe_HP or beyond is using the legacy
I915_GETPARAM ioctl lookups for I915_PARAM_SLICE_MASK and
I915_PARAM_SUBSLICE_MASK (since they've migrated to the more flexible
I915_QUERY ioctl that can return more than a simple u32 value), we take
the opportunity to officially drop support for those GETPARAM lookups on
modern platforms. Maintaining support for these GETPARAM lookups don't
make sense for a number of reasons:
* Traditional slices no longer exist, and newer ideas like gslices,
cslices, mslices, etc. aren't something userspace needs to query
since it can be inferred from other information.
* The GETPARAM ioctl doesn't have a way to distinguish between geometry
subslice masks and compute subslice masks, which are distinct on
Xe_HP and beyond.
* The I915_GETPARAM ioctl is limited to returning a 32-bit value, so
when subslice masks begin to exceed 32-bits (on PVC), it simply can't
return the entire mask.
* The GETPARAM ioctl doesn't have a way to give sensible information
for multi-tile devices.
v2:
- Switch to union of hsw/xehp formats to keep the representation in a
natural format for different types of hardware.
- Avoid accessing internals of intel_sseu_ss_mask_t directly outside of
intel_sseu.[ch].
- Include PVC SSEU which needs the larger SS mask storage enabled by
this series.
v3:
- Correct a BIT(s) typo that should have been BIT(ss), causing
incorrect handling on gen9 platforms.
v4:
- Eliminate sseu->{ss,eu}_stride fields and just calculate the proper
value in the UAPI code that needs them.
- Handle unwanted ~u8 sign extension at the callsite instead of inside
sseu_set_eus.
- Use BITMAP_BITS() macro rather than passing I915_MAX_SS_FUSE_BITS
around directly to bitmap operations.
- Improved debugfs / dmesg reporting for Xe_HP dumps
- Various assertion check improvements.
v5:
- Rebase to latest drm-tip (resolve trivial conflicts)
- Move XEHP_BITMAP_BITS() to the header so that we can also replace a usage of
I915_MAX_SS_FUSE_BITS in one of the inline functions. (Bala)
- Change the local variable in intel_slicemask_from_xehp_dssmask() from u16 to
'unsigned long' to make it a bit more future-proof.
- Incorporate ack's received from Tvrtko and Lionel.

^ permalink raw reply [flat|nested] 25+ messages in thread* [Intel-gfx] [PATCH v5 5/6] drm/i915/sseu: Disassociate internal subslice mask representation from uapi 2022-06-01 15:07 [Intel-gfx] [PATCH v5 0/6] i915: SSEU handling updates Matt Roper @ 2022-06-01 15:07 ` Matt Roper 0 siblings, 0 replies; 25+ messages in thread From: Matt Roper @ 2022-06-01 15:07 UTC (permalink / raw) To: intel-gfx; +Cc: dri-devel As with EU masks, it's easier to store subslice/DSS masks internally in a format that's more natural for the driver to work with, and then only covert into the u8[] uapi form when the query ioctl is invoked. Since the hardware design changed significantly with Xe_HP, we'll use a union to choose between the old "hsw-style" subslice masks or the newer xehp mask. HSW-style masks will be stored in an array of u8's, indexed by slice (there's never more than 6 subslices per slice on older platforms). For Xe_HP and beyond where slices no longer exist, we only need a single bitmask. However we already know that this mask is eventually going to grow too large for a simple u64 to hold, so we'll represent it in a manner that can be operated on by the utilities in linux/bitmap.h. v2: - Fix typo: BIT(s) -> BIT(ss) in gen9_sseu_device_status() v3: - Eliminate sseu->ss_stride and just calculate the stride while specifically handling uapi. (Tvrtko) - Use BITMAP_BITS() macro to refer to size of masks rather than passing I915_MAX_SS_FUSE_BITS directly. (Tvrtko) - Report compute/geometry DSS masks separately when dumping Xe_HP SSEU info. (Tvrtko) - Restore dropped range checks to intel_sseu_has_subslice(). (Tvrtko) v4: - Make the bitmap size macro check the size of the .xehp field rather than the containing union. (Tvrtko) - Don't add GEM_BUG_ON() intel_sseu_has_subslice()'s check for whether slice or subslice ID exceed sseu->max_[sub]slices; various loops in the driver are expected to exceed these, so we should just silently return 'false.' v5: - Move XEHP_BITMAP_BITS() to the header so that we can also replace a usage of I915_MAX_SS_FUSE_BITS in one of the inline functions. (Bala) - Change the local variable in intel_slicemask_from_xehp_dssmask() from u16 to 'unsigned long' to make it a bit more future-proof.
