drm_debugfs_cleanup() now removes all minor->debugfs_list entries automatically, so no need to do this explicitly. Additionally it uses debugfs_remove_recursive() to clean up the debugfs files, so no need for adding fake drm_info_node entries. And finally there's no need to clean up on error, drm_debugfs_cleanup() is called in the error path. Cc: linux@armlinux.org.uk Signed-off-by:

It's still just an experiment, but one lesson learned from drm-misc is that not updating MAINTAINERS just leads to confusion. And this is easy to revert.

I had written most of my comments as if I was describing the individual code files the way I used to for doxygen, while for RST we want to describe things in a more chapter/section way where there's no obvious relation to .c files. Additionally, several of the files had stub descriptions that I've taken this opportunity to extend. Signed-off-by:

Commonly used desktop environments such as xfce4 and gnome on debian sid can flood the graphics drivers with cursor updates. Because the current implementation is waiting for a vblank between cursor updates, this will cause the display to hang for a long time since a typical refresh rate is only 60Hz. This is unnecessary and unexpected by user mode software, so simply swap out the cursor frame buffer without waiting. Signed-off-by:

In the qxl atomic model, the primary doesn't stay pinned all the time, instead it is only pinned/unpinned between prepare_fb and cleanup_fb. So, we no longer need a final unpin of the primary framebuffer when disabling the crtc. Signed-off-by:

Gabriel Krisman Bertazi authored
Every attempt to pin/unpin objects in memory requires qxl_bo_reserve/unreserve calls around the pinning operation to protect the object from concurrent access, which causes that call sequence to be reproduced every place where pinning is needed. In some cases, that sequence was not executed correctly, resulting in potential unprotected pinning operations. This commit encapsulates the reservation inside a new wrapper to make sure it is always handled properly. In cases where reservation must be done beforehand, for some reason, one can use the unprotected version __qxl_bo_pin/unpin. Signed-off-by:

Currently the functions that initialize and tear down a connector iterator use the _get() and _put() suffixes. However, these suffixes are typically used by reference counting functions. Make these function names a little more consistent by changing the suffixes to _begin() and _end(), which is a fairly common pattern in the rest of the Linux kernel. Suggested-by:

For consistency with other reference counting APIs in the kernel, add drm_property_blob_get() and drm_property_blob_put() to reference count DRM blob properties. Compatibility aliases are added to keep existing code working. To help speed up the transition, all the instances of the old functions in the DRM core are already replaced in this commit. A semantic patch is provided that can be used to convert all drivers to the new helpers. Reviewed-by:

Subsequent patches will introduce reference counting APIs that are more consistent with similar APIs throughout the Linux kernel. These APIs use the _get() and _put() suffixes and will collide with this existing function. Rename the function to drm_mode_object_add() which is a slightly more accurate description of what it does. Also the kerneldoc for this function gives an indication that it's badly named because it doesn't actually acquire a reference to anything. Reviewed-by:

Instead of trying to do everything in 1 go, just do a basic safe conversion first. We've been bitten by too many regressions in the past. This patch only converts drm_framebuffer_remove to atomic. The regression sensitive part is split out to a separate patch. v2: - Remove plane->fb assignment, done by drm_atomic_clean_old_fb. - Add WARN_ON when atomic_remove_fb fails. - Always call drm_atomic_state_put. v3: - Use drm_drv_uses_atomic_modeset - Handle the case where the first plane-disable-only commit fails with -EINVAL. Some drivers do not support this, fall back to disabling all crtc's in this case. v4: - Solve vmwgfx compatibility issue in their driver, was fixed in this patch by v3. - Move only disabling primary to a separate patch.

An HLCDC layers in Atmel's nomenclature is either a DRM plane or a 'Post Processing Layer' which can be used to output the results of the HLCDC composition in a memory buffer. atmel_hlcdc_layer.c was designed to be generic enough to be re-usable in both cases, but we're not exposing the post-processing layer yet, and even if we were, I'm not sure the code would provide the necessary tools to manipulate this kind of layer. Moreover, the code in atmel_hlcdc_{plane,layer}.c was designed before the atomic modesetting API, and was trying solve the check-setting/commit-if-ok/rollback-otherwise problem, which is now entirely solved by the existing core infrastructure. And finally, the code in atmel_hlcdc_layer.c is over-complicated compared to what we really need. This rework is a good excuse to simplify it. Note that this rework solves an existing resource leak (leading to a -EBUSY error) which I failed to clearly identify. Signed-off-by:Nicolas Ferre <nicolas.ferre@microchip.com>
