2015-06-04drm/atomic: Clear crtc_state->active in drm_atomic_helper_set_config.Maarten Lankhorst
This fixes some regressions in i915 when converting to atomic. set_config failed with -EINVAL, and I received the following warning in dmesg: [drm:drm_atomic_crtc_check] [CRTC:20] active without enabled Solve this by clearing active when a crtc is disabled. Because crtc_state->enable implies that connectors are active the change from disabled->enabled can only happen for the crtc that's being set_config'd, and checking for !crtc_state->enable is sufficient here.

git://anongit.freedesktop.org/drm-intel into drm-next One more round of drm-misc, again mostly atomic. Big thing is the userspace blob code from Daniel Stone, with support for the mode_id blob now added to the atomic ioctl. Finally we can do atomic modesets! Note that the atomic ioctl is still behind the module knob since the weston patches aren't quite ready yet imo - they lack TEST_ONLY support, which is a fairly crucial bit of the atomic api. But besides that I think it's all good to go. That's also why we didn't bother to hide the new blob ioctls behind the knob, that part won't need to change. And if weston patches get in shape in time we could throw the "atomic by default patch" on top for 4.2. * tag 'topic/drm-misc-2015-05-27' of git://anongit.freedesktop.org/drm-intel: drm: Fix off-by-one in vblank hardware counter wraparound handling drm/atomic: fix out of bounds read in for_each_*_in_state helpers drm/atomic: Add MODE_ID property drm/atomic: Add current-mode blob to CRTC state drm: Add drm_atomic_set_mode_for_crtc drm: check for garbage in unused addfb2 fields drm: Retain reference to blob properties in lookup drm/mode: Add user blob-creation ioctl drm: Return error value from blob creation drm: Allow creating blob properties without copy drm/mode: Unstatic kernel-userspace mode conversion drm/mode: Validate modes inside drm_crtc_convert_umode drm/crtc_helper: Replace open-coded CRTC state helpers drm: kerneldoc fixes for blob properties drm/DocBook: Add more drm_bridge documentation drm: bridge: Allow daisy chaining of bridges drm/atomic: add all affected planes in drm_atomic_helper_check_modeset drm/atomic: add drm_atomic_add_affected_planes drm/atomic: add commit_planes_on_crtc helper

2015-06-03Add virtio gpu driver.Dave Airlie
This patch adds a kms driver for the virtio gpu. The xorg modesetting driver can handle the device just fine, the framebuffer for fbcon is there too. Qemu patches for the host side are under review currently. The pci version of the device comes in two variants: with and without vga compatibility. The former has a extra memory bar for the vga framebuffer, the later is a pure virtio device. The only concern for this driver is that in the virtio-vga case we have to kick out the firmware framebuffer. Initial revision has only 2d support, 3d (virgl) support requires some more work on the qemu side and will be added later.

2015-06-03drm/amdkfd: add H/W debugger IOCTL set definitionsYair Shachar
This patch adds four new IOCTLs to amdkfd. These IOCTLs expose a H/W debugger functionality to the userspace. The IOCTLs are: - AMDKFD_IOC_DBG_REGISTER: The purpose of this IOCTL is to notify amdkfd that a process wants to use GPU debugging facilities on itself only. It is expected that this IOCTL would be called before any other H/W debugger requests are sent to amdkfd and for each GPU where the H/W debugging needs to be enabled. The use of this IOCTL ensures that only one instance of a debugger is active in the system. - AMDKFD_IOC_DBG_UNREGISTER: This IOCTL detaches the debugger/debugged process from the H/W Debug which was established by the AMDKFD_IOC_DBG_REGISTER IOCTL. - AMDKFD_IOC_DBG_ADDRESS_WATCH: This IOCTL allows to set different watchpoints with various conditions as indicated by the IOCTL's arguments. The available number of watchpoints is retrieved from topology. This operation is confined to the current debugged process, which was registered through AMDKFD_IOC_DBG_REGISTER. - AMDKFD_IOC_DBG_WAVE_CONTROL: This IOCTL allows to control a wavefront as indicated by the IOCTL's arguments. For example, you can halt/resume or kill either a single wavefront or a set of wavefronts. This operation is confined to the current debugged process, which was registered through AMDKFD_IOC_DBG_REGISTER. Because the arguments for the address watch IOCTL and wave control IOCTL are dynamic, meaning that they could vary in size, the userspace passes a pointer to a structure (in userspace) that contains the value of the arguments. The kernel driver is responsible to parse this structure and validate its contents. v2: change void* to uint64_t inside ioctl arguments Signed-off-by: Yair Shachar <yair.shachar@amd.com> Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com>

Apparently we can have requests even if though the active list is empty, so do the request retirement regardless of whether there's anything on the active list. The way it happened here is that during suspend intel_ring_idle() notices the olr hanging around and then proceeds to get rid of it by adding a request. However since there was nothing on the active lists i915_gem_retire_requests() didn't clean those up, and so the idle work never runs, and we leave the GPU "busy" during suspend resulting in a WARN later.

It seems 852GM/GMV uses a different HPLLCC encoding than the other 85x platforms. For 852GM/GMV cdclk is always 133MHz. Try to detect that using the PCI revision (sinc the device ID seems useless for that). I'm not at all sure this is a good idea, but according to the specs it should work. v2: Rebased to the latest v3: Rebased to the latest Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> (v1) Signed-off-by: Mika Kahola <mika.kahola@intel.com> Acked-by: Damien Lespiau <damien.lespiau@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2015-05-29drm/i915: Fix i855 get_display_clock_speedVille Syrjälä
Actually read the HPLLCC register insted of assuming it's 0. Fix the HPLLCC bit definitions and all the missing ones from the 852GME spec. 852GME, 854 and 855 all seem to match the same HPLLC encoding even though only some of the values are valid is some of the platforms. v2: Rebased to the latest v3: Rebased to the latest Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> (v1) Signed-off-by: Mika Kahola <mika.kahola@intel.com> Acked-by: Damien Lespiau <damien.lespiau@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

Printing it for PPGTT VMAs only adds noise since we have defined view types are only applicable for GGTT.

2015-05-29drm/i915/skl: Don't try to store the wrong central frequencyDamien Lespiau
The orignal code started by storing the actual central frequency (in Hz, using a uint64_t) in a uint32_t which codes for the register value. That can't be right.
