This reverts commit ae128786. Always free the console font when deinitializing the framebuffer console. Subsequent framebuffer consoles will then use the default font. Rely on userspace to load any user-configured font for these consoles. Commit ae128786 ("fbcon: don't lose the console font across generic->chip driver switch") was introduced to work around losing the font during graphics-device handover. [1][2] It kept a dangling pointer with the font data between loading the two consoles, which is fairly adventurous hack. It also never covered cases when the other consoles, such as VGA text mode, where involved. The problem has meanwhile been solved in userspace. Systemd comes with a udev rule that re-installs the configured font when a console comes up. [3] So the kernel workaround can be removed. This also removes one of the two special cases triggered by setting FBINFO_MISC_FIRMWARE in an fbdev driver. Tested during device handover from efifb and simpledrm to radeon. Udev reloads the configured console font for the new driver's terminal. Signed-off-by:

Remove nouveau's support for legacy contexts and buffers. It was required by libdrm earlier than 2.4.33, released in March 2012. A previous attempt in 2013 to remove the functionality [1] had to be reverted [2] as there were still users left. Libdrm 2.4.33 is now almost 11 years old and it is time for userspace to move on. With the nouveau code gone, we can also remove the driver-feature bit DRIVER_KMS_LEGACY_CONTEXT. Signed-off-by:

With commit 359c6649 ("drm/gem: Implement shadow-plane {begin, end}_fb_access with vmap"), the behavior of the shadow-plane helpers changed and the vunmap is now performed at the end of the current pageflip, instead of the end of the following pageflip.

The documentation for struct drm_minor already states this, but that's not always that easy to find. Also due to historical reasons we still have the minor-centric interfaces (like drm_debugfs_create_files), but since this is now getting fixed we can put a few more pointers in place as to how this should be done ideally. Note that debugfs isn't there yet for all cases (debugfs files on kms objects like crtc/connector aren't supported, neither debugfs files with full fops), so the debugfs side of this is still rather aspirational and more for new users than converting everything existing. todo.rst covers the additional work needed already. Motivated by some discussion with Rodrigo on irc about how drm/xe should lay out its sysfs interfaces. v2: Make the debugfs situation clearer in the commit message, but don't elaborate more in the actual kerneldoc to avoid distracting from the main message around sysfs (Jani) Also fix some typos.
