Those patch series, do some initial preparation DBuf manipulating code
cleanups, i.e remove redundant structures/code, switch to mask
based DBuf manupulation, get into use DBuf assignment according to
BSpec rules.
Stanislav Lisovskiy (5):
drm/i915: Remove skl_ddl_allocation struct
drm/i915: Move dbuf slice update to proper place
drm/i915: Manipulate DBuf slices properly
drm/i915: Introduce parameterized DBUF_CTL
drm/i915: Correctly map DBUF slices to pipes

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)

To: intel-gfx
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"
(Matt Roper)
v4: - Rebase against drm-tip.
- Move post_update closer to optimize_watermarks,
to prevent unneeded noise from underrun reporting

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)
v6: - Now using enum for DBuf slices in this patch (Ville Syrjälä)
- Removed gen11_assert_dbuf_enabled and put gen9_assert_dbuf_enabled
back, as we really need to have a single unified assert here
however currently enabling always slice 1 is enforced by BSpec,
so we will have to OR enabled slices mask with 1 in order
to be consistent with BSpec, that way we can unify that
assertion and against the actual state from the driver, but
not some hardcoded value.(concluded with Ville)
- Remove parameterized DBUF_CTL version, to extract it to another
patch.(Ville Syrjälä)
- Removed unneeded hardcoded return value for older gens from
intel_enabled_dbuf_slices_mask - this now is handled in a
unified manner since device info anyway returns max dbuf slices
as 1 for older platforms(Matthew Roper)
- Now using INTEL_INFO(dev_priv)->num_supported_dbuf_slices instead
of intel_dbuf_max_slices function as it is trivial(Matthew Roper)

Now start using parameterized DBUF_CTL instead
of hardcoded, this would allow shorter access
functions when reading or storing entire state.
Tried to implement it in a MMIO_PIPE manner, however
DBUF_CTL1 address is higher than DBUF_CTL2, which
implies that we have to now subtract from base
rather than add.
v2: - Removed unneeded DBUF_CTL_DIST and DBUF_CTL_ADDR
macros. Started to use _PICK construct as suggested
by Matt Roper.

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)
v7: - Now ORing assigned DBuf slice config always with DBUF_S1
because slice 1 has to be constantly powered on.
(Ville Syrjälä)

I think you added this code in one of the previous patches. So would be
better to make this patch the first in the series so you don't end up
adding code only to rewrite it one patch later.

_DBUF_CTL_S1 etc. is the usual naming pattern for the raw reg offsets.

s/X/slice/ perhaps
_PICK_EVEN() will work just fine here.
With those

Was more or less also expecting to see the enum here, but I guess
that ended up somewhere else?

* [Intel-gfx] [PATCH v12 1/5] drm/i915: Remove skl_ddl_allocation struct
2020-01-15 21:45 [Intel-gfx] [PATCH v12 0/5] Enable second DBuf slice for ICL and TGL Stanislav Lisovskiy

From: Stanislav Lisovskiy @ 2020-01-15 21:45 UTC (permalink / raw)
To: intel-gfx
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)

* [Intel-gfx] [PATCH v12 1/5] drm/i915: Remove skl_ddl_allocation struct
2020-01-15 14:30 [Intel-gfx] [PATCH v12 0/5] Enable second DBuf slice for ICL and TGL Stanislav Lisovskiy

To: intel-gfx
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)
