6 years agodrm/malidp: Enable MMU prefetch on Mali-DP650
Jamie Fox [Mon, 1 Oct 2018 13:39:07 +0000 (14:39 +0100)]
drm/malidp: Enable MMU prefetch on Mali-DP650

Mali-DP650 supports warming up the SMMU translations, by sending
requsts to the SMMU before a buffer is read.

There are two modes supported:

- PARTIAL: could be enabled when the buffer is composed of 4K or 64K
  pages, the display hardware will send a configurable number of
  requests before the actual reading.

- FULL: could be enabled when the buffer is composed of 1M or 2M
  pages, the display hardware will send requests before reading for
  all pages composing the buffer.

This patch adds a mechanism for detecting the page size and set the
MMU prefetch mode if possible.

Changes since v1:
 - For imported buffers use the already populated
   drm_gem_cma_object.sgt instead of calling
   driver.gem_prime_get_sg_table, which works just for buffers
   allocated through the gem_cma API.

6 years agodrm/mali-dp: Implement plane alpha and pixel blend on malidp

drm/mali-dp: Implement plane alpha and pixel blend on malidp

Checks the pixel blending mode and plane alpha value when
do the plane_check. Mali DP supports blending the current plane
with the background either based on the pixel alpha blending
mode or by using the layer's alpha value, but not both at the
same time. If both case, plane_check will return failed.

Sets the HW when doing plane_update accordingly. If plane alpha
is the 0xffff, set the pixel blending bits accordingly. If not
we'd set ALPHA bit as zero and layer alpha value.

Changes since v1:
 - Introduces to use it in the malidp driver, which depends on
   the plane alpha patch
Changes since v2:
 - Refines the comments of drm/mali-dp patchset
Changes since v3:
 - Adds hardware limitation check
Changes since v4:
 - Updates on drm/malidp, hardware limitation check only when
   the format has alpha pixel.
 - Rebases on drm-misc-next.

6 years agodrm/malidp: Fix writeback in NV12
Alexandru Gheorghe [Wed, 22 Aug 2018 15:18:19 +0000 (16:18 +0100)]
drm/malidp: Fix writeback in NV12

When we want to writeback to memory in NV12 format we need to program
the RGB2YUV coefficients. Currently, we don't program the coefficients
and NV12 doesn't work at all.

This patchset fixes that by programming a sane default(bt709, limited
range) as rgb2yuv coefficients.

In the long run, probably we need to think of a way for userspace to
be able to program that, but for now I think this is better than not
working at all or not advertising NV12 as a supported format for
memwrite.

Changes since v1:
 - Write the rgb2yuv coefficients only once, since we don't change
   them at all, just write them the first time NV12 is programmed,
   suggested by Brian Starkey, here [1]

[Why]

The DISPCLK value was previously requested to be 15% higher for all

refactoring of dce_clocks and the dce110 set bandwidth codepath this
was removed for power saving considerations.

That change caused display corruption under certain hardware

[How]

The 15% DISPCLK increase is brought back but only on dce110 for now.

This logic was removed,

Now gamma surface updates are only applied when there is also a plane
info update, this does not work in cases such as using the night light
slider.

[HOW]
When moving the night light slider we will perform a full update if
the gamma has changed and there is a surface, even when the surface
has not changed. Also get stream updates in setgamma prior to
update planes and stream.

virtio: Support prime objects vmap/vunmap

Implement vmap/vunmap so we can export dmabufs to
other drivers, such as video4linux.

Tested with a virtio-gpu / vivid (virtual capture driver)
pipeline, where the vivid driver imports the dmabufs exported
by virtio-gpu.

Note that dma_buf_vmap() does its own vmap counting, so
it's not needed to take care of it in the driver.

virtio: Rework virtio_gpu_object_kmap()

Currently, virtio_gpu_object_kmap() is only called by
virtio_gpufb_create(), when a DRM framebuffer is created.

Thus, instead of returning the vmap'ed address, emit a warning
if virtio_gpu_object_kmap is called on an already mapped
object. With this change, kmap/kunmap calls are now balanced.

virtio: Add virtio_gpu_object_kunmap()

Implement a virtio_gpu_object_kunmap() to unmap the kernel
mapping, and use it in the TTM object destroy path.
