All the components of YUV420 over DP are added. Therefore, let's mark the
connector property as true for DP connector when the DP type is not eDP
and when there is a CDM block available.
Changes in v3:
- Move setting the connector's ycbcr_420_allowed parameter so
that it is not dependent on if the dp_display is not eDP
Changes in v2:
- Check for if dp_catalog has a CDM block available instead of
checking if VSC SDP is allowed when setting the dp connector's
ycbcr_420_allowed parameter

DP controller can be setup to operate in either SDP update flush mode or
peripheral flush mode based on the DP controller hardware version.
Starting in DP v1.2, the hardware documents require the use of
peripheral flush mode for SDP packets such as PPS OR VSC SDP packets.
In-line with this guidance, lets program the DP controller to use
peripheral flush mode starting DP v1.2
Changes in v4:
- Clear up that DP_MAINLINK_CTRL_FLUSH_MODE register requires
the use of bits [24:23]
- Modify macros DP_MAINLINK_FLUSH_MODE_UPDATE_SDP and
DP_MAINLINK_FLUSH_MODE_SDP_PERIPH_UPDATE to explicitly set
their values in the bits of DP_MAINLINK_CTRL_FLUSH_MODE_MASK
Changes in v3:
- Clear up that the DP_MAINLINK_FLUSH_MODE_SDE_PERIPH_UPDATE
macro is setting bits [24:23] to a value of 3
Changes in v2:
- Use the original dp_catalog_hw_revision() function to
correctly check the DP HW version

Add support to pack and send the VSC SDP packet for DP. This therefore
allows the transmision of format information to the sinks which is
needed for YUV420 support over DP.
Changes in v5:
- Slightly modify use of drm_dp_vsc_sdp_pack()
- Remove dp_catalog NULL checks
- Modify dp_utils_pack_sdp_header() to more clearly pack the
header buffer
- Move dp_utils_pack_sdp_header() inside of
dp_catalog_panel_send_vsc_sdp to clearly show the relationship
between the header buffer and the vsc_sdp struct
- Due to the last point, remove the dp_utils_pack_vsc_sdp()
function and only call drm_dp_vsc_sdp_pack() in
dp_panel_setup_vsc_sdp_yuv_420()
Changes in v4:
- Remove struct msm_dp_sdp_with_parity
- Use dp_utils_pack_sdp_header() to pack the SDP header and
parity bytes into a buffer
- Use this buffer when writing the VSC SDP data in
dp_catalog_panel_send_vsc_sdp()
- Write to all of the MMSS_DP_GENERIC0 registers instead of just
the ones with non-zero values
Changes in v3:
- Create a new struct, msm_dp_sdp_with_parity, which holds the
packing information for VSC SDP
- Use drm_dp_vsc_sdp_pack() to pack the data into the new
msm_dp_sdp_with_parity struct instead of specifically packing
for YUV420 format
- Modify dp_catalog_panel_send_vsc_sdp() to send the VSC SDP
data using the new msm_dp_sdp_with_parity struct
Changes in v2:
- Rename GENERIC0_SDPSIZE macro to GENERIC0_SDPSIZE_VALID
- Remove dp_sdp from the dp_catalog struct since this data is
being allocated at the point used
- Create a new function in dp_utils to pack the VSC SDP data
into a buffer
- Create a new function that packs the SDP header bytes into a
buffer. This function is made generic so that it can be
utilized by dp_audio
header bytes into a buffer
- Create a new function in dp_utils that takes the packed buffer
and writes to the DP_GENERIC0_* registers
- Split the dp_catalog_panel_config_vsc_sdp() function into two

- Check the DP HW version using the original useage of
dp_catalog_hw_revision() and correct the version checking

If an eDP panel is not powered on then any attempts to talk to it over
the DP AUX channel will timeout. Unfortunately these attempts may be
quite slow. Userspace can initiate these attempts either via a
/dev/drm_dp_auxN device or via the created i2c device.
Making the DP AUX drivers timeout faster is a difficult proposition.
In theory we could just poll the panel's HPD line in the AUX transfer
function and immediately return an error there. However, this is
easier said than done. For one thing, there's no hard requirement to
hook the HPD line up for eDP panels and it's OK to just delay a fixed
amount. For another thing, the HPD line may not be fast to probe. On
parade-ps8640 we need to wait for the bridge chip's firmware to boot
before we can get the HPD line and this is a slow process.
The fact that the transfers are taking so long to timeout is causing
real problems. The open source fwupd daemon sometimes scans DP busses
looking for devices whose firmware need updating. If it happens to
scan while a panel is turned off this scan can take a long time. The
fwupd daemon could try to be smarter and only scan when eDP panels are
turned on, but we can also improve the behavior in the kernel.
Let's let eDP panels drivers specify that a panel is turned off and
then modify the common AUX transfer code not to attempt a transfer in
this case.

We found a regression in v5.10 on real-time server, using the
rt-kernel and the mgag200 driver. It's some really specialized
workload, with <10us latency expectation on isolated core.
After the v5.10, the real time tasks missed their <10us latency
when something prints on the screen (fbcon or printk)
The regression has been bisected to 2 commits:
commit 0b34d58b6c32 ("drm/mgag200: Enable caching for SHMEM pages")
commit 4862ffaec523 ("drm/mgag200: Move vmap out of commit tail")
The first one changed the system memory framebuffer from Write-Combine
to the default caching.
Before the second commit, the mgag200 driver used to unmap the
framebuffer after each frame, which implicitly does a cache flush.
Both regressions are fixed by this commit, which restore WC mapping
for the framebuffer in system memory, and add a cache flush.
This is only needed on x86_64, for low-latency workload,
so the new kconfig DRM_MGAG200_IOBURST_WORKAROUND depends on
PREEMPT_RT and X86.
