[PATCH v4 00/10] drm: Add GEM backed framebuffer library
by Noralf Trønnes 01 Oct '17

01 Oct '17

This adds helpers for drivers that don't subclass drm_framebuffer and are backed by drm_gem_object(s). drm_fb_cma_helper is converted to use the helpers. Ack's have been trickling in the last month but seem to have stopped now, so these are the ones left plus a new one: tve200 Noralf. Changes since version 3: - Added tve200 Changes since version 2: - Expanded docs (Daniel) - Add drm_gem_fbdev_fb_create() instead of exporting drm_gem_fb_alloc(). This function is used by drivers/helpers to create a drm_framebuffer for use with fbdev emulation. - drm_gem_object_put_unlocked() is NULL tolerant (Joe Kniss) - Rebase tinydrm patch on new st7586 driver - Rebase arc and pl111 patches on 'drm: make drm_mode_config_func const' Changes since version 1: - Pushed the new functions out to the cma drivers, so I could clean up the cma library.

[PATCH 1/2] drm/etnaviv: rework clock initialization
by Lucas Stach 01 Oct '17

01 Oct '17

The reset path wants to initialize the clock control register regardless of the DYNAMIC_FREQUENCY_SCALING feature, so don't call clock update, but explicitly load the register. Also disabling of the debug registers is moved into the reset function, so we always get to the same state after a GPU reset. This means the clock update function should not touch the bits already set in the clock control register, but instead only update the scaling bits.
