2017-12-18drm/tilcdc: Remove drm_framebuffer_get() and *_put() callsJyri Sarha1-49/+0
The drm_framebuffer_get() and drm_framebuffer_put() calls in the tilcdc driver are obsolete. The drm atomic modesetting core should take care of holding the references while the atomic state object is in use. The old state is deleted when a commit of a new one is completed after drm_atomic_helper_wait_for_vblanks(). This also fixes an occasional framebuffer leak the old drm_framebuffer_get() and drm_framebuffer_put() code had. Signed-off-by: Jyri Sarha <[email protected]>
2017-12-18drm/tilcdc: ensure nonatomic iowrite64 is not usedLogan Gunthorpe1-1/+1
Add a check to ensure iowrite64 is only used if it is atomic. It was decided in [1] that the tilcdc driver should not be using an atomic operation (so it was left out of this patchset). However, it turns out that through the drm code, a nonatomic header is actually included: include/linux/io-64-nonatomic-lo-hi.h is included from include/drm/drm_os_linux.h:9:0, from include/drm/drmP.h:74, from include/drm/drm_modeset_helper.h:26, from include/drm/drm_atomic_helper.h:33, from drivers/gpu/drm/tilcdc/tilcdc_crtc.c:19: And thus, without this change, this patchset would inadvertantly change the behaviour of the tilcdc driver.

2017-12-16drm/i915: Restore the kernel context after a GPU reset on an idle engineChris Wilson1-0/+19
As part of the system requirement for powersaving is that we always have a context loaded. Upon boot and resume, we load the kernel_context to ensure that some valid state is set before powersaving kicks in, we should do so after a full GPU reset as well. We only need to do so for an idle engine, as any active engines will restart by executing the stuck request, loading its context. For the idle engine, we create a new request to load the kernel_context instead. For whatever reason, perfoming a dummy execute on the idle engine after reset papers over a subsequent GPU hang in rare circumstances, even on machines not using contexts (e.g. Pineview).

2017-12-15drm/sun4i: validate modes for HDMIHans Verkuil1-0/+19
When I connected my cubieboard running 4.15-rc1 to my 4k display I got no picture. Some digging found that there is no check against the upper pixelclock limit of the HDMI output, so X selects a 4kp60 format at 594 MHz, which obviously won't work. The patch below adds a check for the upper bound of what this hardware can do, and it checks if the requested tmds clock can be obtained. It also allows for the +/- 0.5% pixel clock variation that the HDMI spec permits. That code is based on commit 22d0be2a557e ("drm: arcpgu: Allow some clock deviation in crtc->mode_valid() callback") from Jose Abreu for drm/arc.

2017-12-15drm/atomic: document how to handle driver private objectsDaniel Vetter1-3/+42
DK put some nice docs into the commit introducing driver private state, but in the git history alone it'll be lost. Also, since Ville remove the void* usage it's a good opportunity to give the driver private stuff some tlc on the doc front. Finally try to explain why the "let's just subclass drm_atomic_state" approach wasn't the greatest, and annotate all those functions as deprecated in favour of more standardized driver private states. Also note where we could/should extend driver private states going forward (atm neither locking nor synchronization is handled in core/helpers, which isn't really all that great). v2: Spelling and phrasing improvements (Alex, DK).
