drm/rockchip: dsi: remove extra component_del() call

commit cf6d100dd238 ("drm/rockchip: dsi: add dual mipi support") added
this devcnt field and call to component_del(). However, these both
appear to be erroneous changes left over from an earlier version of the
patch. In the version merged, nothing ever modifies devcnt, meaning
component_del() runs unconditionally and in addition to the
component_del() calls in dw_mipi_dsi_rockchip_host_detach(). The second
call fails to delete anything and produces a warning in dmesg.

If we look at the previous version of the patch[1], however, we see that
it had logic to calculate devcnt and call component_add() in certain
situations. This was removed in v6, and the fact that the deletion code
was not appears to have been an oversight.

3 years agodrm/rockchip: dsi: move all lane config except LCDC mux to bind()
Thomas Hebb [Mon, 19 Apr 2021 02:04:10 +0000 (19:04 -0700)]
drm/rockchip: dsi: move all lane config except LCDC mux to bind()

When we first enable the DSI encoder, we currently program some per-chip
configuration that we look up in rk3399_chip_data based on the device
tree compatible we match. This data configures various parameters of the
MIPI lanes, including on RK3399 whether DSI1 is slaved to DSI0 in a
dual-mode configuration. It also selects which LCDC (i.e. VOP) to scan
out from.

This causes a problem in RK3399 dual-mode configurations, though: panel
prepare() callbacks run before the encoder gets enabled and expect to be
able to write commands to the DSI bus, but the bus isn't fully
functional until the lane and master/slave configuration have been
programmed. As a result, dual-mode panels (and possibly others too) fail
to turn on when the rockchipdrm driver is initially loaded.

Because the LCDC mux is the only thing we don't know until enable time
(and is the only thing that can ever change), we can actually move most
of the initialization to bind() and get it out of the way early. That's
what this change does. (Rockchip's 4.4 BSP kernel does it in mode_set(),
which also avoids the issue, but bind() seems like the more correct
place to me.)

Tested on a Google Scarlet board (Acer Chromebook Tab 10), which has a
Kingdisplay KD097D04 dual-mode panel. Prior to this change, the panel's
backlight would turn on but no image would appear when initially loading
rockchipdrm. If I kept rockchipdrm loaded and reloaded the panel driver,
it would come on. With this change, the panel successfully turns on
during initial rockchipdrm load as expected.

commit 2aae8ed1f390 ("drm/rockchip: Add per-pixel alpha support for the PX30 VOP")
alpha support was introduced for PX30's VOP.
RK3036, RK3066, RK3126 and RK3188 VOPs support alpha blending in the
same manner.
With the exception of RK3066 all of them support pre-multiplied alpha.

drm/rockchip: remove existing generic drivers to take over the device

There are drivers that register framebuffer devices very early in the boot
process and make use of the existing framebuffer as setup by the firmware.

If one of those drivers has registered a fbdev, then the fallback fbdev of
the DRM driver won't be bound to the framebuffer console. To avoid that,
remove any existing generic driver and take over the graphics device.

By doing that, the fb mapped to the console is switched correctly from the
early fbdev to the one registered by the rockchip DRM driver:

This is intended to enable direct high-precision scanout and pageflip
of Vulkan swapchain images in format VK_FORMAT_R16G16B16A16_UNORM.

Expose DRM_FORMAT_XRGB16161616, DRM_FORMAT_ARGB16161616,
DRM_FORMAT_XBGR16161616 and DRM_FORMAT_ABGR16161616 as 16 bpc

suggests that these 16 bpc formats are supported by all DCE and
DCN display engines, so we can expose the formats unconditionally.

Successfully tested on AMD Polaris11 DCE-11.2 an RavenRidge DCN-1.0

Add the necessary format definition, bandwidth and pixel size mappings,
prescaler setup, and pixelformat selection, following the logic
already present for SURFACE_PIXEL_FORMAT_GRPH_ARGB16161616.

The new SURFACE_PIXEL_FORMAT_GRPH_ABGR16161616 is implemented as the
old SURFACE_PIXEL_FORMAT_GRPH_ARGB16161616 format, but with swapped
red <-> green color channel, by use of the hardware xbar.

Please note that on the DCN 1/2/3 display engines, the pixelformat
in hubp and dpp setup for the old SURFACE_PIXEL_FORMAT_GRPH_ARGB16161616
and the new SURFACE_PIXEL_FORMAT_GRPH_ABGR16161616 was changed from
format id 22 to id 26. See amd/include/navi10_enum.h for the meaning
of the id's.

For format 22, the display engine read the framebuffer in 16 bpc format,
but truncated to the 12 bpc actually supported by later pipeline stages.
However, the engine took the 12 LSB of each color component for
truncation, which is incompatible with rendering at least under Vulkan,
where content is 16 bit wide, and a 12 MSB alignment would be appropriate,
if any. Format 20 for ARGB16161616_12MSB does work, but even better, we
can choose format 26 for ARGB16161616_UNORM, keeping all 16 bits around
until later stages of the display pipeline.

This allows to directly consume what the rendering hw produces under
Vulkan for swapchain format VK_FORMAT_R16G16B16A16_UNORM, as tested
with a patched version of the current AMD open-source amdvlk driver
which maps swapchain format VK_FORMAT_R16G16B16A16_UNORM onto
DRM_FORMAT_XBGR16161616.

The old id 22 would cause colorful pixeltrash to be displayed instead.
