The AST driver establishes several memory mappings for frame buffers and cursors. This patch converts the driver to use the equivalent drm_gem_vram_kmap() functions. It removes the dependencies on TTM and cleans up the code. Signed-off-by:

There's now a pointer to struct drm_vram_mm stored in struct drm_device. DRM drivers that use VRAM MM should use this field to refer to their instance of the data structure. Appropriate helpers are now provided as well. Adding struct drm_vram_mm to struct drm_device further avoids wrappers and boilerplate code in drivers. This patch implements default functions for callbacks in struct drm_driver and struct file_operations that use the struct drm_vram_mm stored in struct drm_device. Drivers that need to provide their own implementations can still do so. The patch also adds documentation for the VRAM helper library in general. v5: * set .llseek to no_llseek() from DRM_VRAM_MM_FILE_OPERATIONS v4: * cleanups from checkpatch.pl * document VRAM helper library Signed-off-by:

VRAM MM is most likely be used with GEM VRAM. The latter now provides the required instance of struct drm_vram_mm_funcs for drivers to use. Signed-off-by:

Thomas Zimmermann authored
The VRAM MM memory manager is a helper library that manages dedicated video memory of simple framebuffer devices. It is supported to be used with struct drm_gem_vram_object, but does not depend on it. The implementation is based on the respective code from ast, bochs, and mgag200. These drivers share the exact same implementation except for type names. The helpers are currently build with TTM. This may change in future revisions. v4: * cleanups from checkpatch.pl v2: * renamed to struct drm_vram_mm * add drm_vram_mm_mmap() helper * documentation fixes Signed-off-by:

These basic helper functions for GEM VRAM allow for pinning and mapping GEM VRAM objects via the PRIME interfaces. It's not a full implementation, but complete enough for generic fbcon. Signed-off-by:

The helper function drm_gem_vram_fill_create_dumb() implements most of struct drm_driver.dumb_create() for GEM-VRAM buffer objects. It's not a full implementation of the callback, as several driver-specific parameters are still required. v4: * cleanups from checkpatch.pl v2: * documentation fixes Signed-off-by:

Thomas Zimmermann authored
The type |struct drm_gem_vram_object| implements a GEM object for simple framebuffer devices with dedicated video memory. The BO is either located in VRAM or system memory. The implementation has been created from the respective code in ast, bochs and mgag200. These drivers copy their implementation from each other; except for the names of several data types. The helpers are currently build with TTM, but this is considered an implementation detail and may change in future updates. v5: * do WARN_ON_ONCE for pin-count mismatches * allocate only 2 entries in placements array v4: * cleanups from checkpatch.pl * removed several fixed-size types from interfaces * DRM_VRAM_HELPER now selects DRM_TTM * remove separate config option for GEM VRAM v2: * rename to |struct drm_gem_vram_object| * move drm_is_gem_ttm() to a later patch in the series * add drm_gem_vram_kmap_at() * return is_iomem from kmap functions * redefine TTM placement flags for public interface * documentation fixes Signed-off-by:

drm_fb_helper_is_bound() is used to check if DRM userspace is in control. This is done by looking at the fb on the primary plane. By the time fb-helper gets around to committing, it's possible that the facts have changed. Avoid this race by holding the drm_device->master_mutex lock while committing. When DRM userspace does its first open, it will now wait until fb-helper is done. The helper will stay away if there's a master. Two igt tests fail with the new 'bail out if master' rule. Work around this by relaxing this rule for drm_fb_helper_restore_fbdev_mode_unlocked() until the tests have been fixed. Add todo entry for this. Locking rule: Always take the fb-helper lock first. v5: drm_fb_helper_restore_fbdev_mode_unlocked(): Use restore_fbdev_mode_force() v2: - Remove drm_fb_helper_is_bound() (Daniel Vetter) - No need to check fb_helper->dev->master in drm_fb_helper_single_fb_probe(), restore_fbdev_mode() has the check.

Move the open helper around to avoid the forward decl, and give drm_setup a drm_legacy_ prefix since it's all legacy stuff in there. v2: Move drm_legacy_setup into drm_legacy_misc.c (Chris). The counterpart in the form of drm_legacy_dev_reinit is there already too, plus it fits perfectly into Dave's work of making DRIVER_LEGACY code compile-time optional.

This is the 2nd pull request for the malidp-next. The new patches add additional support for Arm Mali D71 so that it can now be enabled correctly and brought up on any SoC that contains the IP. From now on we will start focusing on adding writeback, scaling and other useful features to bring the driver to the same level of maturity as mali-dp. Signed-off-by:

Depending on platform firmware, a zap shader may not be required to take the GPU out of secure mode on boot, in which case we can just write RBBM_SECVID_TRUST_CNTL directly. Which we *mostly* handled, but missed clearing 'ret' resulting that hw_init() returned an error on these devices. Fixes: abccb9fe ("drm/msm/a6xx: Add zap shader load") Acked-by:

As discussed with Nicholas and Daniel Vetter (patchwork link to discussion below), the VRR timestamping behaviour produced utterly useless and bogus vblank/pageflip timestamps. We have found a way to fix this and provide sane behaviour. As of Linux 5.2, the amdgpu driver will be able to provide exactly the same vblank / pageflip timestamp semantic in variable refresh rate mode as in standard fixed refresh rate mode. This is achieved by deferring core vblank handling (drm_crtc_handle_vblank()) until the end of front porch, and also defer the sending of pageflip completion events until end of front porch, when we can safely compute correct pageflip/vblank timestamps. The same approach will be possible for other VRR capable kms drivers, so we can actually have sane and useful timestamps in VRR mode. This patch removes the section of the docs that describes the broken timestamp behaviour present in Linux 5.0/5.1.

For most drivers, drm_fence_init is followed by drm_fence_emit immediately. But for our driver, they are done separately. We also don't know the fence seqno until drm_fence_emit. Signed-off-by:

This is motivated by having meaningful ftrace events, but it also fixes use cases where dma_fence_is_later is called, such as in sync_file_merge. In other drivers, fence creation and cmdbuf submission normally happen atomically, mutex_lock(); fence = dma_fence_create(..., ++timeline->seqno); submit_cmdbuf(); mutex_unlock(); and have no such issue. But in our driver, because most ioctls queue commands into ctrlq, we do not want to grab a lock. Instead, we set seqno to 0 when a fence is created, and update it when the command is finally queued and the seqno is known. Signed-off-by:
