Pull kcmp kconfig update from Daniel Vetter: "Make the kcmp syscall available independently of checkpoint/restore. drm userspaces uses this, systemd uses this, so makes sense to pull it out from the checkpoint-restore bundle. Kees reviewed this from security pov and is happy with the final version" Link: https://lwn.net/Articles/845448/ * tag 'topic/kcmp-kconfig-2021-02-22' of git://anongit.freedesktop.org/drm/drm: kcmp: Support selection of SYS_kcmp without CHECKPOINT_RESTORE

kcmp: Support selection of SYS_kcmp without CHECKPOINT_RESTORE

2021-02-16T08:59:41+00:00

Userspace has discovered the functionality offered by SYS_kcmp and has started to depend upon it. In particular, Mesa uses SYS_kcmp for os_same_file_description() in order to identify when two fd (e.g. device or dmabuf) point to the same struct file. Since they depend on it for core functionality, lift SYS_kcmp out of the non-default CONFIG_CHECKPOINT_RESTORE into the selectable syscall category. Rasmus Villemoes also pointed out that systemd uses SYS_kcmp to deduplicate the per-service file descriptor store. Note that some distributions such as Ubuntu are already enabling CHECKPOINT_RESTORE in their configs and so, by extension, SYS_kcmp.

drm: Merge CONFIG_DRM_VM into CONFIG_DRM_LEGACY

CONFIG_DRM_VM gets selected by CONFIG_DRM_LEGACY, but nothing else. So remove it and build drm_vm.o as part of CONFIG_DRM_LEGACY.

drm/gem: Use struct dma_buf_map in GEM vmap ops and convert GEM backends

2020-11-09T08:19:24+00:00

This patch replaces the vmap/vunmap's use of raw pointers in GEM object functions with instances of struct dma_buf_map. GEM backends are converted as well. For most of them, this simply changes the returned type. TTM-based drivers now return information about the location of the memory, either system or I/O memory. GEM VRAM helpers and qxl now use ttm_bo_vmap() et al. Amdgpu, nouveau and radeon use drm_gem_ttm_vmap() et al instead of implementing their own vmap callbacks. v7: * init QXL cursor to mapped BO buffer (kernel test robot) v5: * update vkms after switch to shmem v4: * use ttm_bo_vmap(), drm_gem_ttm_vmap(), et al. (Daniel, Christian) * fix a trailing { in drm_gem_vmap() * remove several empty functions instead of converting them (Daniel) * comment uses of raw pointers with a TODO (Daniel) * TODO list: convert more helpers to use struct dma_buf_map Signed-off-by: Thomas Zimmermann Acked-by: Christian König Tested-by: Sam Ravnborg Link: https://patchwork.freedesktop.org/patch/msgid/20201103093015.1063-7-tzimmermann@suse.de

drm/vkms: Switch to shmem helpers

2020-10-15T21:37:58+00:00

Inspired by a patch by Chris Wilson for vgem. Plus this gives us vmap at the gem bo level, which we need for generic fbdev emulation. Luckily shmem also tracks ->vaddr, so we just need to adjust the code all over a bit to make this fit. Also wire up handle_to_fd, dunno why that was missing. v2: - Drop now unused container_of #define (Melissa) - Make sure we keep creating cached objects, this is for testing (Thomas) Signed-off-by: Daniel Vetter Cc: Chris Wilson Cc: Maarten Lankhorst Cc: Maxime Ripard Cc: Thomas Zimmermann Cc: David Airlie Cc: Daniel Vetter Cc: Rodrigo Siqueira Cc: Melissa Wen Cc: Haneen Mohammed Acked-by: Thomas Zimmermann Reviewed-by: Melissa Wen Link: https://patchwork.freedesktop.org/patch/msgid/20201013111027.375999-1-daniel.vetter@ffwll.ch

drm: xlnx: DRM/KMS driver for Xilinx ZynqMP DisplayPort Subsystem

2020-07-17T23:59:16+00:00

The Xilinx ZynqMP SoC has a hardened display pipeline named DisplayPort Subsystem. It includes a buffer manager, a video pipeline renderer (blender), an audio mixer and a DisplayPort source controller (transmitter). The DMA engine the provide data to the buffer manager, as well as the DisplayPort PHYs that drive the lanes, are external to the subsystem and interfaced using the DMA engine and PHY APIs respectively. This driver supports the DisplayPort Subsystem and implements - Two planes, for graphics and video - One CRTC that supports alpha blending - One encoder for the DisplayPort transmitter - One connector for an external monitor It currently doesn't support - Color keying - Test pattern generation - Audio - Live input from the Programmable Logic (FPGA) - Output to the Programmable Logic (FPGA) Signed-off-by: Hyun Kwon Signed-off-by: Laurent Pinchart
