drm/msm/dpu: Fix PP_BLK_DIPHER -> DITHER typo · 701f6918

Marijn Suijten authored Apr 27, 2023

SM8550 exclusively has a DITHER sub-block inside the PINGPONG block and
no other registers, hence the DITHER name of the macro and a
corresponding PINGPONG block length of zero. However, the PP_BLK_ macro
name was typo'd to DIPHER rather than DITHER.

drm/msm/dpu: Remove TE2 block and feature from DPU >= 5.0.0 hardware · cfbc21d1

Marijn Suijten authored Apr 27, 2023

No hardware beyond kona (sm8250, DPU 6.0.0) defines the TE2 PINGPONG
sub-block offset downstream, and according to insiders no DPU >= 5.0.0
hardware has support for it either. Especially since neither downstream
nor upstream utilize these registers in any way, remove the erroneous
specification from SM8150, SC8180X, SM8250, SC7180, SM8350, SC8280XP and
SM8450 to prevent confusion.

Note that downstream enables the PPSPLIT (split-FIFO) topology (single
LM for 2 PP and 2 INTF) based on the presence of a TE2 block.

drm/msm/dpu: tweak lm pairings in msm8998 hw catalog · 686eb89b

Arnaud Vrac authored Apr 19, 2023

Change lm blocks pairs so that lm blocks with the same features are
paired together:

LM_0 and LM_1 with PP and DSPP
LM_2 and LM_5 with PP
LM_3 and LM_4

This matches the sdm845 configuration and allows using pp or dspp when 2
lm blocks are needed in the topology. In the previous config the
reservation code could never find an lm pair without a matching feature
set.

drm/msm/dp: unregister audio driver during unbind · 85c63628

Srinivas Kandagatla authored Apr 21, 2023

while binding the code always registers a audio driver, however there
is no corresponding unregistration done in unbind. This leads to multiple
redundant audio platform devices if dp_display_bind and dp_display_unbind
happens multiple times during startup. On X13s platform this resulted in
6 to 9 audio codec device instead of just 3 codec devices for 3 dp ports.

Fix this by unregistering codecs on unbind.

But, as with msm_gem_get_vaddr_active(), this is a special case
because we know that the buffer won't be purged evicted until it's
fence is signaled. We just forgot to propagate the logic get_vaddr()
to pin_pages_locked().
