[PATCH v5 11/13] video: Use VIDEO_DAMAGE for VIDEO_COPY
Alper Nebi Yasak
alpernebiyasak at gmail.com
Mon Aug 21 15:51:08 CEST 2023
From: Alexander Graf <agraf at csgraf.de>
CONFIG_VIDEO_COPY implemented a range-based copying mechanism: If we
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.
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.

[Alper: Rebase for fontdata->height/w, fill_part(), fix memmove(dev),
drop from defconfig, use damage.xstart/yend, use IS_ENABLED(),
call video_sync() before copy_fb check, update video_copy test]

Changes in v5:
- Remove video_sync_copy() also from video_fill(), video_fill_part()
- Fix memmove() calls by removing the extra dev argument
- Call video_sync() before checking copy_fb in video tests
- Use xstart, ystart, xend, yend as names for damage region
- Use met->baseline instead of priv->baseline
- Use fontdata->height/width instead of VIDEO_FONT_HEIGHT/WIDTH
- Use xstart, ystart, xend, yend as names for damage region
- Use IS_ENABLED() instead of CONFIG_IS_ENABLED()
- Drop VIDEO_DAMAGE from sandbox defconfig added in a new patch
- Update dm_test_video_copy test added in a new patch
Changes in v3:
- Make VIDEO_COPY always select VIDEO_DAMAGE
Changes in v2:
- Add patch "video: Use VIDEO_DAMAGE for VIDEO_COPY"

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.
