[PATCH 0/2] arm64: dts: Add sdm845 GPU/GMU and SMMU
by Jordan Crouse 16 Mar '18

16 Mar '18

Building on the sdm845 changes from Rajendra and SMMU changes from Vivek this is an initial stab at the DT nodes for the sdm845 GPU and GMU (graphics management unit) which is responsible for the direct power control of the GPU including the companion arm-smmu-v2 compatible SMMU. Please refer to https://patchwork.freedesktop.org/series/37428/ for the driver code.

[GIT PULL] mali-dp: fixes for drm-next
by Liviu Dudau 16 Mar '18

16 Mar '18

Hi Dave, I have accumulated some patches as we went through some internal testing for mali-dp and I was waiting for the YUV2RGB patches to land in your tree, so I would like to get them into drm-next at your earliest convenient time. Please note that after you pull Dan Carpenter's patch f2f2c85c6620 ("drm: mali-dp: Uninitialized variable in malidp_se_check_scaling()") you will get a conflict with Ville's commit 81af63a4af82 ("drm: Don't pass clip to drm_atomic_helper_check_plane_state()") in drm-misc-next. The way it was fixed in linux-next was: diff --cc drivers/gpu/drm/arm/malidp_planes.c index ee32361c87ac,b2d11df6b5e1..000000000000 --- a/drivers/gpu/drm/arm/malidp_planes.c +++ b/drivers/gpu/drm/arm/malidp_planes.c @@@ -147,7 -147,13 +146,9 @@@ static int malidp_se_check_scaling(stru if (!crtc_state) return -EINVAL; - if (crtc_state->enable) - drm_mode_get_hv_timing(&crtc_state->mode, - &clip.x2, &clip.y2); - + mc = to_malidp_crtc_state(crtc_state); + - ret = drm_atomic_helper_check_plane_state(state, crtc_state, &clip, + ret = drm_atomic_helper_check_plane_state(state, crtc_state, 0, INT_MAX, true, true); if (ret) return ret; Please pull.

[PATCH] drm/imx: move arming of the vblank event to atomic_flush
by Lucas Stach 16 Mar '18

16 Mar '18

Right now the vblank event completion is racing with the atomic update, which is especially bad when the PRE is in use, as one of the hardware issue workaround might extend the atomic commit for quite some time. If the vblank IRQ happens to trigger during that time, we will prematurely signal the atomic commit completion to userspace, which causes tearing when userspace re-uses a framebuffer we haven't managed to flip away from yet.

[PATCH 1/6] Revert "drm: Use a flexible array member for blob property data"
by Ville Syrjala 16 Mar '18

16 Mar '18

From: Ville Syrjälä <ville.syrjala(a)linux.intel.com> Using a flexible array for the blob data was a mistake by me. It forces all users of the blob data to cast blob->data to something else. void* is clearly superior so let's go back to the original scheme. Not a clean revert as the code has moved.

Since HW cursor updates are always supposed to work without delay, and there is no sign of an issue in the attached userspace information, this seems like a kernel (DC?) issue.

[PATCH 00/16] remove eight obsolete architectures
by Arnd Bergmann 16 Mar '18

16 Mar '18

Here is the collection of patches I have applied to my 'asm-generic' tree on top of the 'metag' removal. This does not include any of the device drivers, I'll send those separately to a someone different list of people. The removal came out of a discussion that is now documented at https://lwn.net/Articles/748074/ Following up from the state described there, I ended up removing the mn10300, tile, blackfin and cris architectures directly, rather than waiting, after consulting with the respective maintainers. However, the unicore32 architecture is no longer part of the removal, after its maintainer Xuetao Guan said that the port is still actively being used and that he intends to keep working on it, and that he will try to provide updated toolchain sources. In the end, it seems that while the eight architectures are extremely different, they all suffered the same fate: There was one company in charge of an SoC line, a CPU microarchitecture and a software ecosystem, which was more costly than licensing newer off-the-shelf CPU cores from a third party (typically ARM, MIPS, or RISC-V). It seems that all the SoC product lines are still around, but have not used the custom CPU architectures for several years at this point.
