Generate callback functions for struct fb_ops with the fbdev macro FB_GEN_DEFAULT_DEFERRED_IOMEM_OPS(). Initialize struct fb_ops to the generated functions with fbdev initializer macros. The hyperv_fb driver is incomplete in its handling of deferred I/O and damage framebuffers. Write operations do no trigger damage handling. Fixing this is beyond the scope of this patch.

Context with SSID = 1 is reserved and accesses on that context happen only when context is uninitialized on the VPU side. Such access triggers MMU fault (0xa) "Invalid CD Fetch", which doesn't contain any useful information besides context ID. This commit will change that state, now (0x10) "Translation fault" will be triggered and accessed address will shown in the log. Signed-off-by:

The mutex was completely pointless in the first place since any parallel adding of files to this list would result in random behavior since the list is filled and consumed multiple times. Completely drop that approach and just create the files directly but return -ENODEV while opening the file when the minors are not registered yet. v2: rebase on debugfs directory rework, limit access before minors are registered.

Christian König authored
Instead of the per minor directories only create a single debugfs directory for the whole device directly when the device is initialized. For DRM devices each minor gets a symlink to the per device directory for now until we can be sure that this isn't useful any more in any way. Accel devices create only the per device directory and also drops the mid layer callback to create driver specific files. v2: cleanup accel component as well v3: fix typo when debugfs is disabled v4: call drm_debugfs_dev_fini() during release as well, some kerneldoc typos fixed v5: rebased and one more kerneldoc fix Signed-off-by:
