Subject: [PATCH 01/13] video: test: Split copy frame buffer check into a
|
|
|
|
function
|
|
|
|
|
|
|
|
While checking frame buffer contents, the video tests also check if the
|
|
|
|
copy frame buffer contents match the main frame buffer. To test if only
|
|
|
|
the modified regions are updated after a sync, we will need to create
|
|
|
|
situations where the two are mismatched. Split this check into another
|
|
|
|
function that we can skip calling, since we won't want it to error on
|
|
|
|
those mismatched cases.

Subject: [PATCH 02/13] video: test: Support checking copy frame buffer
|
|
|
|
contents
|
|
|
|
|
|
|
|
The video tests have a helper function to generate a pseudo-digest of
|
|
|
|
frame buffer contents, but it only does so for the main one. There is
|
|
|
|
another check that the copy frame buffer is the same as that. But
|
|
|
|
neither is enough to test if only the modified regions are copied to the
|
|
|
|
copy frame buffer, since we will want the two to be different in very
|
|
|
|
specific ways.
|
|
|
|
|
|
|
|
Add a boolean argument to the existing helper function to indicate which
|
|
|
|
frame buffer we want to inspect, and update the existing callers.

Subject: [PATCH 03/13] video: test: Test partial updates of hardware frame
|
|
|
|
buffer
|
|
|
|
|
|
|
|
With VIDEO_COPY enabled, only the modified parts of the frame buffer are
|
|
|
|
intended to be copied to the hardware. Add a test that checks this, by
|
|
|
|
overwriting contents we prepared without telling the video uclass and
|
|
|
|
then checking if the overwritten contents have been redrawn on the next
|
|
|
|
sync.

Subject: [PATCH 04/13] dm: video: Add damage tracking API
|
2022-12-07 10:53:19 +00:00
|
|
|
|
|
|
|
We are going to introduce image damage tracking to fasten up screen
|
|
|
|
refresh on large displays. This patch adds damage tracking for up to
|
|
|
|
one rectangle of the screen which is typically enough to hold blt or
|
|
|
|
text print updates. Callers into this API and a reduced dcache flush
|
|
|
|
code path will follow in later patches.

Subject: [PATCH 07/13] video: test: Test video damage tracking via vidconsole
|
|
|
|
|
|
|
|
With VIDEO_DAMAGE, the video uclass tracks updated regions of the frame
|
|
|
|
buffer in order to avoid unnecessary work during a video sync. Enable
|
|
|
|
the config in sandbox and add a test for it, by printing strings at a
|
|
|
|
few locations and checking the tracked region.

Let's report the video damage when we draw a bitmap on the screen. This

|
|

way we can later lazily flush only relevant regions to hardware.

Subject: [PATCH 10/13] video: Only dcache flush damaged lines
|
2022-12-07 10:53:19 +00:00
|
|
|
|
|
|
|
Now that we have a damage area tells us which parts of the frame buffer
|
|
|
|
actually need updating, let's only dcache flush those on video_sync()
|
|
|
|
calls. With this optimization in place, frame buffer updates - especially
|
|
|
|
on large screen such as 4k displays - speed up significantly.

Subject: [PATCH 11/13] video: Use VIDEO_DAMAGE for VIDEO_COPY
|
2022-12-07 10:53:19 +00:00
|
|
|
|
2023-10-13 09:44:05 +00:00
|
|
|
CONFIG_VIDEO_COPY implemented a range-based copying mechanism: If we
|
2022-12-07 10:53:19 +00:00
|
|
|
print a single character, it will always copy the full range of bytes
|
|
|
|
from the top left corner of the character to the lower right onto the
|
|
|
|
uncached frame buffer. This includes pretty much the full line contents
|
|
|
|
of the printed character.
|
|
|
|
|
|
|
|
Since we now have proper damage tracking, let's make use of that to reduce
|
|
|
|
the amount of data we need to copy. With this patch applied, we will only
|
|
|
|
copy the tiny rectangle surrounding characters when we print them,
|
|
|
|
speeding up the video console.
|
|
|
|
|
2023-10-13 09:44:05 +00:00
|
|
|
After this, changes to the main frame buffer are not immediately copied
|
|
|
|
to the copy frame buffer, but postponed until the next video device
|
|
|
|
sync. So issue an explicit sync before inspecting the copy frame buffer
|
|
|
|
contents for the video tests.

On some machines (e.g. x86), reading from the frame buffer is very
|
|
|
|
slow because it is uncached. To improve performance, this feature
|
|
|
|
allows the frame buffer to be kept in cached memory (allocated by
|
|
|
|
U-Boot) and then copied to the hardware frame-buffer as needed.
|
|
|
|
+ It uses the VIDEO_DAMAGE feature to keep track of regions to copy
|
|
|
|
+ and will only copy actually touched regions.
|
|
|
|
|
|
|
|
To use this, your video driver must set @copy_base in
|
|
|
|
struct video_uc_plat.

Subject: [PATCH 12/13] video: Always compile cache flushing code
|
|
|
|
|
|
|
|
The dcache flushing code path was conditional on ARM && !DCACHE config
|
|
|
|
options. However, dcaches exist on other platforms as well and may need
|
|
|
|
clearing if their driver requires it.
|
|
|
|
|
|
|
|
Simplify the compile logic and always enable the dcache flush logic in
|
|
|
|
the video core. That way, drivers can always rely on it to call the arch
|
|
|
|
specific callbacks.
|
|
|
|
|
|
|
|
This will increase code size for non-ARM platforms with CONFIG_VIDEO=y
|
|
|
|
slightly.

Subject: [PATCH 13/13] video: Enable VIDEO_DAMAGE for drivers that need it
|
|
|
|
|
|
|
|
Some drivers call video_set_flush_dcache() to indicate that they want to
|
|
|
|
have the dcache flushed for the frame buffer. These drivers benefit from
|
|
|
|
our new video damage control, because we can reduce the amount of memory
|
|
|
|
that gets flushed significantly.
|
|
|
|
|
|
|
|
This patch enables video damage control for all device drivers that call
|
|
|
|
video_set_flush_dcache() to make sure they benefit from it.
|
|
