2018-10-24drm: dsi: Add lane clock rate fields to DSI deviceLinus Walleij
The DSI devices have a maximum operating frequency specified in their data sheet per the MIPI specification, and DSI hosts that can scale their frequency need this information to set their clock dividers right. As current panel drivers often lack this information, specify that setting it to zero will make the DSI host use some reasonable default.

convert drm_atomic_helper_suspend/resume() to use drm_mode_config_helper_suspend/resume(). remove suspend_state field from the rcar_du_device structure as it is no more required. With this conversion, also drm_fbdev_cma_set_suspend_unlocked() will left with no consumer. So this function can be removed.

2018-10-18drm: add syncobj timeline support v9Chunming Zhou
This patch is for VK_KHR_timeline_semaphore extension, semaphore is called syncobj in kernel side: This extension introduces a new type of syncobj that has an integer payload identifying a point in a timeline. Such timeline syncobjs support the following operations: * CPU query - A host operation that allows querying the payload of the timeline syncobj. * CPU wait - A host operation that allows a blocking wait for a timeline syncobj to reach a specified value. * Device wait - A device operation that allows waiting for a timeline syncobj to reach a specified value. * Device signal - A device operation that allows advancing the timeline syncobj to a specified value. v1: Since it's a timeline, that means the front time point(PT) always is signaled before the late PT. a. signal PT design: Signal PT fence N depends on PT[N-1] fence and signal opertion fence, when PT[N] fence is signaled, the timeline will increase to value of PT[N]. b. wait PT design: Wait PT fence is signaled by reaching timeline point value, when timeline is increasing, will compare wait PTs value with new timeline value, if PT value is lower than timeline value, then wait PT will be signaled, otherwise keep in list. syncobj wait operation can wait on any point of timeline, so need a RB tree to order them. And wait PT could ahead of signal PT, we need a sumission fence to perform that. v2: 1. remove unused DRM_SYNCOBJ_CREATE_TYPE_NORMAL. (Christian) 2. move unexposed denitions to .c file. (Daniel Vetter) 3. split up the change to drm_syncobj_find_fence() in a separate patch. (Christian) 4. split up the change to drm_syncobj_replace_fence() in a separate patch. 5. drop the submission_fence implementation and instead use wait_event() for that. (Christian) 6. WARN_ON(point != 0) for NORMAL type syncobj case. (Daniel Vetter) v3: 1. replace normal syncobj with timeline implemenation. (Vetter and Christian) a. normal syncobj signal op will create a signal PT to tail of signal pt list. b. normal syncobj wait op will create a wait pt with last signal point, and this wait PT is only signaled by related signal point PT. 2. many bug fix and clean up 3. stub fence moving is moved to other patch. v4： 1. fix RB tree loop with while(node=rb_first(...)). (Christian) 2. fix syncobj lifecycle. (Christian) 3. only enable_signaling when there is wait_pt. (Christian) 4. fix timeline path issues. 5. write a timeline test in libdrm v5: (Christian) 1. semaphore is called syncobj in kernel side. 2. don't need 'timeline' characters in some function name. 3. keep syncobj cb. v6: (Christian) 1. merge syncobj_timeline to syncobj structure. 2. simplify some check sentences. 3. some misc change. 4. fix CTS failed issue. v7: (Christian) 1. error handling when creating signal pt. 2. remove timeline naming in func. 3. export flags in find_fence. 4. allow reset timeline. v8: 1. use wait_event_interruptible without timeout 2. rename _TYPE_INDIVIDUAL to _TYPE_BINARY v9: 1. rename signal_pt->base to signal_pt->fence_array to avoid misleading 2. improve kerneldoc individual syncobj is tested by ./deqp-vk -n dEQP-VK*semaphore* timeline syncobj is tested by ./amdgpu_test -s 9 Signed-off-by: Chunming Zhou <david1.zhou@amd.com> Signed-off-by: Christian König <christian.koenig@amd.com> Cc: Christian Konig <christian.koenig@amd.com> Cc: Dave Airlie <airlied@redhat.com> Cc: Daniel Rakos <Daniel.Rakos@amd.com> Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Bas Nieuwenhuizen <bas@basnieuwenhuizen.nl> Cc: Jason Ekstrand <jason@jlekstrand.net> Reviewed-by: Christian König <christian.koenig@amd.com> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/257258/

2018-09-25drm: move native byte order quirk to new drm_driver_legacy_fb_format functionGerd Hoffmann
Turns out we need the pixel format fixup not only for the addfb ioctl, but also for fbdev emulation code. Ideally we would place it in drm_mode_legacy_fb_format(). That would create alot of churn though, and most drivers don't care because they never ever run on a big endian platform.

2018-09-13drm: Introduce per-device driver_featuresVille Syrjälä
We wish to control certain driver_features flags on a per-device basis while still sharing a single drm_driver instance across all the devices. To that end introduce device.driver_features. By default it will be set to ~0 to not impose any limits beyond driver.driver_features. Drivers can then clear specific flags in the per-device bitmask to limit the capabilities of the device. An alternative approach would be to copy the driver_features from the driver into the device in drm_dev_init(), however that would require verifying that no driver is currently changing driver.driver_features after drm_dev_init(). Hence the ~0 apporach was easier. Ideally we'd also make drm_driver const but there is plenty of code left that wants to mutate it (eg. various vfunc assignments). We'll need to fix all that up before we can make it const. And while at it fix up the type of the feature flag passed to drm_core_check_feature(). v2: Streamline the && vs. & (Chris) s/int/u32/ in drm_core_check_feature() args Cc: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180913131622.17690-1-ville.syrjala@linux.intel.com Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Reviewed-by: Michel Dänzer <michel.daenzer@amd.com>

2018-09-09drm: extract drm_atomic_uapi.cDaniel Vetter
This leaves all the commit/check and state handling in drm_atomic.c, while pulling all the uapi glue and the huge ioctl itself into a seprate file. This seems to almost perfectly split the rather big drm_atomic.c file into 2 equal sizes. Also adjust the kerneldoc and type a very terse overview text. v2: Rebase. v3: Fix tiny typo. v4: - Fixup armada, newly converted atomic driver hooray! - Fixup msm/dpu1, newly added too.

2018-09-06drm: fix drm_mode_addfb() on big endian machines.Gerd Hoffmann
Userspace on big endian machhines typically expects the ADDFB ioctl returns a big endian framebuffer. drm_mode_addfb() will call drm_mode_addfb2() unconditionally with little endian DRM_FORMAT_* values though, which is wrong. This patch fixes that. Drivers (both kernel and xorg) have quirks in place to deal with the broken drm_mode_addfb() behavior. Because of this we can't just change drm_mode_addfb() behavior for everybody without breaking things. Add the quirk_addfb_prefer_host_byte_order field to mode_config, so drivers can opt-in.
