Current consensus that it is redundant as
we already have skl_ddb_values struct out there,
also this struct contains only single member
which makes it unnecessary.
v2: As dirty_pipes soon going to be nuked away
from skl_ddb_values, evacuating enabled_slices
to safer in dev_priv.
v3: Changed "enabled_slices" to be "enabled_dbuf_slices_num"
(Matt Roper)
v4: - Wrapped the line getting number of dbuf slices(Matt Roper)
- Removed indeed redundant skl_ddb_values declaration(Matt Roper)

Current DBuf slices update wasn't done in proper
place, especially its "post" part, which should
disable those only once vblank had passed and
all other changes are committed.
v2: Fix to use dev_priv and intel_atomic_state
instead of skl_ddb_values
(to be nuked in Villes patch)
v3: Renamed "enabled_slices" to "enabled_dbuf_slices_num"

To: intel-gfx
Start manipulating DBuf slices as a mask,
but not as a total number, as current approach
doesn't give us full control on all combinations
of slices, which we might need(like enabling S2
only can't enabled by setting enabled_slices=1).
Removed wrong code from intel_get_ddb_size as
it doesn't match to BSpec. For now still just
use DBuf slice until proper algorithm is implemented.
Other minor code refactoring to get prepared
for major DBuf assignment changes landed:
- As now enabled slices contain a mask
we still need some value which should
reflect how much DBuf slices are supported
by the platform, now device info contains
num_supported_dbuf_slices.
- Removed unneeded assertion as we are now
manipulating slices in a more proper way.
v2: Start using enabled_slices in dev_priv
v3: "enabled_slices" is now "enabled_dbuf_slices_mask",
as this now sits in dev_priv independently.
v4: - Fixed debug print formatting to hex(Matt Roper)
- Optimized dbuf slice updates to be used only
if slice union is different from current conf(Matt Roper)
- Fixed some functions to be static(Matt Roper)
- Created a parameterized version for DBUF_CTL to
simplify DBuf programming cycle(Matt Roper)
- Removed unrequred field from GEN10_FEATURES(Matt Roper)
v5: - Removed redundant programming dbuf slices helper(Ville Syrjälä)
- Started to use parameterized loop for hw readout to get slices
(Ville Syrjälä)
- Added back assertion checking amount of DBUF slices enabled
after DC states 5/6 transition, also added new assertion
as starting from ICL DMC seems to restore the last DBuf
power state set, rather than power up all dbuf slices
as assertion was previously expecting(Ville Syrjälä)

Should be just DBUF_CTL_S(i) since it's the index we want to pass.

From: Stanislav Lisovskiy @ 2019-12-23 15:45 UTC (permalink / raw)
To: intel-gfx
Added proper DBuf slice mapping to correspondent
pipes, depending on pipe configuration as stated
in BSpec.
v2:
- Remove unneeded braces
- Stop using macro for DBuf assignments as
it seems to reduce readability.
v3: Start using enabled slices mask in dev_priv
v4: Renamed "enabled_slices" used in dev_priv
to "enabled_dbuf_slices_mask"(Matt Roper)
v5: - Removed redundant parameters from
intel_get_ddb_size function.(Matt Roper)
- Made i915_possible_dbuf_slices static(Matt Roper)
- Renamed total_width into total_width_in_range
so that it now reflects that this is not
a total pipe width but the one in current
dbuf slice allowed range for pipe.(Matt Roper)
- Removed 4th pipe for ICL in DBuf assignment
table(Matt Roper)
- Fixed wrong DBuf slice in DBuf table for TGL
(Matt Roper)
- Added comment regarding why we currently not
using pipe ratio for DBuf assignment for ICL
v6: - Changed u32 to unsigned int in
icl_get_first_dbuf_slice_offset function signature
(Ville Syrjälä)
- Changed also u32 to u8 in dbuf slice mask structure
(Ville Syrjälä)
- Switched from DBUF_S1_BIT to enum + explicit
BIT(DBUF_S1) access(Ville Syrjälä)
- Switched to named initializers in DBuf assignment
arrays(Ville Syrjälä)
- DBuf assignment arrays now use autogeneration tool
from
https://patchwork.freedesktop.org/series/70493/
to avoid typos.
- Renamed i915_find_pipe_conf to *_compute_dbuf_slices
(Ville Syrjälä)
- Changed platforms ordering in skl_compute_dbuf_slices
to be from newest to oldest(Ville Syrjälä)
