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)
v8: - Added pipe_name for neater printing(Ville Syrjälä)
- Renamed width_before_pipe to width_before_pipe_in_range,
to better reflect that now all the calculations are happening
inside DBuf range allowed by current pipe configuration mask
(Ville Syrjälä)
- Shortened FIXME comment message, regarding constant ORing with
DBUF_S1(Ville Syrjälä)
- Added .dbuf_mask named initializer to pipe assignment array
(Ville Syrjälä)
- Edited pipe assignment array to use only single DBuf slice
for gen11 single pipe configurations, until "pipe ratio"
thing is finally sorted out(Ville Syrjälä)
- Removed unused parameter crtc_state for now(Ville Syrjälä)
from icl/tgl_compute_dbuf_slices function
