Subject: drm/rockchip: vop2: Do not divide height twice for YUV

For the cbcr format, gt2 and gt4 are computed again after src_h has been
divided by vsub.

As src_h as already been divided by 2 before, introduce cbcr_src_h and
cbcr_src_w to keep a copy of those values to be used for cbcr gt2 and
gt4 computation.

This fixes yuv planes being unaligned vertically when down scaling to
1080 pixels from 2160.

Subject: drm/panthor: clean up some types in panthor_sched_suspend()

These variables should be u32 instead of u64 because they're only
storing u32 values.  Also static checkers complain when we do:

	suspended_slots &= ~upd_ctx.timedout_mask;

In this code "suspended_slots" is a u64 and "upd_ctx.timedout_mask".  The
mask clears out the top 32 bits which would likely be a bug if anything
were stored there.

Subject: drm/edid: Parse topology block for all DispID structure v1.x
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

DisplayID spec v1.3 revision history notes do claim that
the toplogy block was added in v1.3 so requiring structure
v1.2 would seem correct, but there is at least one EDID in
edid.tv with a topology block and structure v1.0. And
there are also EDIDs with DisplayID structure v1.3 which
seems to be totally incorrect as DisplayID spec v1.3 lists
structure v1.2 as the only legal value.

Unfortunately I couldn't find copies of DisplayID spec
v1.0-v1.2 anywhere (even on vesa.org), so I'll have to
go on empirical evidence alone.

We used to parse the topology block on all v1.x
structures until the check for structure v2.0 was added.
Let's go back to doing that as the evidence does suggest
that there are DisplayIDs in the wild that would miss
out on the topology stuff otherwise.

Also toss out DISPLAY_ID_STRUCTURE_VER_12 entirely as
it doesn't appear we can really use it for anything.

I *think* we could technically skip all the structure
version checks as the block tags shouldn't conflict
between v2.0 and v1.x. But no harm in having a bit of
extra sanity checks I guess.

So far I'm not aware of any user reported regressions
from overly strict check, but I do know that it broke
igt/kms_tiled_display's fake DisplayID as that one
gets generated with structure v1.0.

Subject: drm/buddy: Implement tracking clear page feature
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add tracking clear page feature.

- Driver should enable the DRM_BUDDY_CLEARED flag if it
  successfully clears the blocks in the free path. On the otherhand,
  DRM buddy marks each block as cleared.

- Track the available cleared pages size

- If driver requests cleared memory we prefer cleared memory
  but fallback to uncleared if we can't find the cleared blocks.
  when driver requests uncleared memory we try to use uncleared but
  fallback to cleared memory if necessary.

- When a block gets freed we clear it and mark the freed block as cleared,
  when there are buddies which are cleared as well we can merge them.
  Otherwise, we prefer to keep the blocks as separated.

- Add a function to support defragmentation.

v1:
  - Depends on the flag check DRM_BUDDY_CLEARED, enable the block as
    cleared. Else, reset the clear flag for each block in the list(Christian)
  - For merging the 2 cleared blocks compare as below,
    drm_buddy_is_clear(block) != drm_buddy_is_clear(buddy)(Christian)
  - Defragment the memory beginning from min_order
    till the required memory space is available.

v2: (Matthew)
  - Add a wrapper drm_buddy_free_list_internal for the freeing of blocks
    operation within drm buddy.
  - Write a macro block_incompatible() to allocate the required blocks.
  - Update the xe driver for the drm_buddy_free_list change in arguments.
  - add a warning if the two blocks are incompatible on
    defragmentation
  - call full defragmentation in the fini() function
  - place a condition to test if min_order is equal to 0
  - replace the list with safe_reverse() variant as we might
    remove the block from the list.

v3:
  - fix Gitlab user reported lockup issue.
  - Keep DRM_BUDDY_HEADER_CLEAR define sorted(Matthew)
  - modify to pass the root order instead max_order in fini()
    function(Matthew)
  - change bool 1 to true(Matthew)
  - add check if min_block_size is power of 2(Matthew)
  - modify the min_block_size datatype to u64(Matthew)

v4:
  - rename the function drm_buddy_defrag with __force_merge.
  - Include __force_merge directly in drm buddy file and remove
    the defrag use in amdgpu driver.
  - Remove list_empty() check(Matthew)
  - Remove unnecessary space, headers and placement of new variables(Matthew)
  - Add a unit test case(Matthew)

v5:
  - remove force merge support to actual range allocation and not to bail
    out when contains && split(Matthew)
  - add range support to force merge function.

v6:
  - modify the alloc_range() function clear page non merged blocks
    allocation(Matthew)
  - correct the list_insert function name(Matthew).

From a68c7eaa7a8ffdec9287ba1561a668d674c20a13 Mon Sep 17 00:00:00 2001
From: Arunpravin Paneer Selvam <Arunpravin.PaneerSelvam@amd.com>
Date: Fri, 19 Apr 2024 12:05:37 +0530
Subject: drm/amdgpu: Enable clear page functionality
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add clear page support in vram memory region.

v1(Christian):
  - Dont handle clear page as TTM flag since when moving the BO back
    in from GTT again we don't need that.
  - Make a specialized version of amdgpu_fill_buffer() which only
    clears the VRAM areas which are not already cleared
  - Drop the TTM_PL_FLAG_WIPE_ON_RELEASE check in
    amdgpu_object.c

v2:
  - Modify the function name amdgpu_ttm_* (Alex)
  - Drop the delayed parameter (Christian)
  - handle amdgpu_res_cleared(&cursor) just above the size
    calculation (Christian)
  - Use AMDGPU_GEM_CREATE_VRAM_WIPE_ON_RELEASE for clearing the buffers
    in the free path to properly wait for fences etc.. (Christian)

v3(Christian):
  - Remove buffer clear code in VRAM manager instead change the
    AMDGPU_GEM_CREATE_VRAM_WIPE_ON_RELEASE handling to set
    the DRM_BUDDY_CLEARED flag.
  - Remove ! from amdgpu_res_cleared(&cursor) check.

v4(Christian):
  - vres flag setting move to vram manager file
  - use dma_fence_get_stub in amdgpu_ttm_clear_buffer function
  - make fence a mandatory parameter and drop the if and the get/put dance

Subject: drm/tests: Add a test case for drm buddy clear allocation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add a new test case for the drm buddy clear and dirty
allocation.

v2:(Matthew)
  - make size as u32
  - rename PAGE_SIZE with SZ_4K
  - dont fragment the address space for all the order allocation
    iterations. we can do it once and just increment and allocate
    the size.
  - create new mm with non power-of-two size to ensure the multi-root
    force_merge during fini.

v3:
  - add randomness in size calculation(Matthew)

Subject: drm/bridge: add lvds controller support for sam9x7

Add a new LVDS controller driver for sam9x7 which does the following:
- Prepares and enables the LVDS Peripheral clock
- Defines its connector type as DRM_MODE_CONNECTOR_LVDS and adds itself
to the global bridge list.
- Identifies its output endpoint as panel and adds it to the encoder
display pipeline
- Enables the LVDS serializer

Subject: dt-bindings: display: bridge: tc358775: make stby gpio optional

For a normal operation, the stby GPIO is not needed.

The reset pin is required because once the PPI (PHY protocol interface)
is started, it can only be stopped by asserting the reset pin.

Subject: dt-bindings: display: bridge: tc358775: Add data-lanes

The device uses a clock lane, and 1 to 4 DSI data lanes. Let's add the
data-lanes property starting at 1 similar to what the other bridge
bindings are doing.

Let's also drop the data-lanes properties in the example for the DSI host
controller to avoid confusion. The configuration of the DSI host depends
on the controller used and is unrelated to the bridge binding.

The tc358765 is similar to tc358775. The tc358765 just an earlier version
of the hardware, and it's pin and register compatible with tc358775 for
most part.

From the binding point of view the only difference is that the tc358765
does not have stdby-gpios.

Subject: drm/bridge: tc358775: fix support for jeida-18 and jeida-24

The bridge always uses 24bpp internally. Therefore, for jeida-18
mapping we need to discard the lowest two bits for each channel and thus
starting with LV_[RGB]2. jeida-24 has the same mapping but uses four
lanes instead of three, with the forth pair transmitting the lowest two
bits of each channel. Thus, the mapping between jeida-18 and jeida-24
is actually the same, except that one channel is turned off (by
selecting the RGB666 format in VPCTRL).

While at it, remove the bogus comment about the hardware default because
the default is overwritten in any case.

Tested with a jeida-18 display (Evervision VGG644804).

Subject: drm/bridge: tc358775: make standby GPIO optional

The stby pin is optional. It is only needed for power-up and down
sequencing. It is not needed, if the power rails cannot by dynamically
enabled.

Because the GPIO is now optional, remove the error message.

Subject: drm/bridge: tc358775: Get bridge data lanes instead of the DSI host
 lanes

The current code assumes the data-lanes property is configured on the
DSI host side instead of the bridge side, and assumes DSI host endpoint 1.

Let's standardize on what the other bridge drivers are doing and parse the
data-lanes property for the bridge. Only if data-lanes property is not found,
let's be nice and also check the DSI host for old dtb in use and warn.

And as Dmitry pointed out, the lanes for the host and the bridge may be
different because the lanes may be swapped on the host side.

Subject: drm/bridge: tc358775: Add support for tc358765

The tc358775 bridge is pin compatible with earlier tc358765 according to
the tc358774xbg_datasheet_en_20190118.pdf documentation. Compared to the
tc358765, the tc358775 supports a STBY GPIO and higher data rates.

The tc358765 has a register bit for video event mode vs video pulse mode.
We must set it to video event mode for the LCD output to work, and on the
tc358775, this bit no longer exists.

Looks like the registers seem to match otherwise based on a quick glance
comparing the defines to the earlier Android kernel tc358765 driver.

Subject: drm/v3d: Create two functions to update all GPU stats variables
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently, we manually perform all operations to update the GPU stats
variables. Apart from the code repetition, this is very prone to errors,
as we can see on commit 35f4f8c9fc97 ("drm/v3d: Don't increment
`enabled_ns` twice").

Therefore, create two functions to manage updating all GPU stats
variables. Now, the jobs only need to call for `v3d_job_update_stats()`
when the job is done and `v3d_job_start_stats()` when starting the job.

From b136b1953f201542ae5cdfee4b35e9a2e4aa16fa Mon Sep 17 00:00:00 2001
From: Maíra Canal <mcanal@igalia.com>
Date: Sat, 20 Apr 2024 18:32:10 -0300
Subject: drm/v3d: Create a struct to store the GPU stats
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This will make it easier to instantiate the GPU stats variables and it
will create a structure where we can store all the variables that refer
to GPU stats.

Note that, when we created the struct `v3d_stats`, we renamed
`jobs_sent` to `jobs_completed`. This better express the semantics of
the variable, as we are only accounting jobs that have been completed.

Create a function to decouple the stats calculation from the printing.
This will be useful in the next step when we add a seqcount to protect
the stats.

Subject: drm/v3d: Fix race-condition between sysfs/fdinfo and interrupt
 handler
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In V3D, the conclusion of a job is indicated by a IRQ. When a job
finishes, then we update the local and the global GPU stats of that
queue. But, while the GPU stats are being updated, a user might be
reading the stats from sysfs or fdinfo.

For example, on `gpu_stats_show()`, we could think about a scenario where
`v3d->queue[queue].start_ns != 0`, then an interrupt happens, we update
the value of `v3d->queue[queue].start_ns` to 0, we come back to
`gpu_stats_show()` to calculate `active_runtime` and now,
`active_runtime = timestamp`.

In this simple example, the user would see a spike in the queue usage,
that didn't match reality.

In order to address this issue properly, use a seqcount to protect read
and write sections of the code.

It is pointless to set register load before disabling the register. This

Subject: drm/bridge: adv7511: make it honour next bridge in DT

DT bindings for adv7511 and adv7533 bridges specify HDMI output to be
present at the port@1. This allows board DT to add e.g. HDMI connector
nodes or any other next chained bridge. Make adv7511 driver discover
that bridge and attach it to the chain.

Subject: drm: xlnx: zynqmp_dpsub: Set layer mode during creation

Set layer mode of operation (live or dma-based) during layer creation.

Each DPSUB layer mode of operation is defined by corresponding DT node port
connection, so it is possible to assign it during layer object creation.
Previously it was set in layer enable functions, although it is too late
as setting layer format depends on layer mode, and should be done before
given layer enabled.

Subject: drm: xlnx: zynqmp_dpsub: Anounce supported input formats

DPSUB in bridge mode supports multiple input media bus formats.

Announce the list of supported input media bus formats via
drm_bridge.atomic_get_input_bus_fmts callback. Introduce a set of live
input formats supported by DPSUB. Add safeguards to format list functions
to prevent their misuse in the different layer modes contexts.

Subject: drm: xlnx: zynqmp_dpsub: Minimize usage of global flag

Avoid usage of global zynqmp_dpsub.dma_enabled flag in DPSUB layer
context. This flag signals whether the driver runs in DRM CRTC or DRM
bridge mode, assuming that all display layers share the same live or
non-live mode of operation. Using per-layer mode instead of global flag
will simplify future support of the hybrid scenario.

Remove redundant checks in DMA request/release contexts as
zynqmp_disp_layer.info is well-defined for all layer types, including the
correct number of DMA channels required for each particular layer.

Subject: drm: xlnx: zynqmp_dpsub: Set input live format

Program live video input format according to selected media bus format.

In the bridge mode of operation, DPSUB is connected to FPGA CRTC which
almost certainly supports a single media bus format as its output. Expect
this to be delivered via the new bridge atomic state. Program DPSUB
registers accordingly.

Subject: drm/bridge: imx: Fix unmet depenency for PHY_FSL_SAMSUNG_HDMI_PHY

When enabling i.MX8MP DWC HDMI driver, it automatically selects
PHY_FSL_SAMSUNG_HDMI_PHY, since it wont' work without the phy.
This may cause some Kconfig warnings during various build tests.
Fix this by implying the phy instead of selecting the phy.

To prevent this from happening with the DRM_IMX8MP_HDMI_PVI, also
imply it instead of selecting it.

Fixes: 1f36d634670d ("drm/bridge: imx: add bridge wrapper driver for i.MX8MP DWC HDMI")

Subject: drm/print: drop include debugfs.h and include where needed

Surprisingly many places depend on debugfs.h to be included via
drm_print.h. Fix them.

v3: Also fix armada, ite-it6505, imagination, msm, sti, vc4, and xe

v2: Also fix ivpu and vmwgfx
