drm: drop obsolete drm_core.h The drm_core.h header contains a set of constants meant to be used throughout DRM. However, as it turns out, they're each used just once and don't bring any benefit. They're also grossly mis-named and lack name-spacing. This patch inlines them, or moves them into drm_internal.h as appropriate: - CORE_AUTHOR and CORE_DESC are inlined into corresponding MODULE_*() macros. It's just confusing having to follow 2 pointers when trying to find the definition of these fields. Grep'ping for MODULE_AUTHOR() should reveal the full information, if there's no strong reason not to. - CORE_NAME, CORE_DATE, CORE_MAJOR, CORE_MINOR, and CORE_PATCHLEVEL are inlined into the sysfs 'version' attribute. They're stripped everywhere else (which is just some printk() statements). CORE_NAME just doesn't make *any* sense, as we hard-code it in many places, anyway. The other constants are outdated and just serve binary-compatibility purposes. Hence, inline them in 'version' sysfs attribute (we might even try dropping it..). - DRM_IF_MAJOR and DRM_IF_MINOR are moved into drm_internal.h as they're only used by the global ioctl handlers. Furthermore, versioning interfaces breaks backports and as such is deprecated, anyway. We just keep them for historic reasons. I doubt anyone will ever modify them again.

drm: Add API for capturing frame CRCs Adds files and directories to debugfs for controlling and reading frame CRCs, per CRTC: dri/0/crtc-0/crc dri/0/crtc-0/crc/control dri/0/crtc-0/crc/data Drivers can implement the set_crc_source callback() in drm_crtc_funcs to start and stop generating frame CRCs and can add entries to the output by calling drm_crtc_add_crc_entry. v2: - Lots of good fixes suggested by Thierry. - Added documentation. - Changed the debugfs layout. - Moved to allocate the entries circular queue once when frame generation gets enabled for the first time. v3: - Use the control file just to select the source, and start and stop capture when the data file is opened and closed, respectively. - Make variable the number of CRC values per entry, per source. - Allocate entries queue each time we start capturing as now there isn't a fixed number of CRC values per entry. - Store the frame counter in the data file as a 8-digit hex number. - For sources that cannot provide useful frame numbers, place XXXXXXXX in the frame field. v4: - Build only if CONFIG_DEBUG_FS is enabled. - Use memdup_user_nul. - Consolidate calculation of the size of an entry in a helper. - Add 0x prefix to hex numbers in the data file. - Remove unnecessary snprintf and strlen usage in read callback. v5: - Made the crcs array in drm_crtc_crc_entry fixed-size - Lots of other smaller improvements suggested by Emil Velikov v7: - Move definition of drm_debugfs_crtc_crc_add to drm_internal.h v8: - Call debugfs_remove_recursive when we fail to create the minor device v9: - Register the debugfs directory for a crtc from drm_crtc_register_all() v10: - Don't let debugfs failures interrupt CRTC registration (Emil Velikov) v11: - Remove extra brace that broke compilation.
