When the video timings are suitably aligned so that all different periods start at phase 0 (ie. none of the periods start mid-pixel) we can inform the sink about this. Supposedly the sink can then optimize certain things. Obviously this is only relevant when outputting >8bpc data since otherwise there are no mid-pixel phases. v2: Rebased due to crtc->config changes Signed-off-by:

GCP infoframes are required to inform the HDMI sink about the color depth. Send the GCP infoframe whenever the sink supports any deep color modes since such sinks must anyway be capable of receiving them. For sinks that don't support deep color let's skip the GCP in case it might confuse the sink, although HDMI 1.4 spec does say all sinks must be capable of reciving them. In theory we could skip the GCP infoframe for deep color sinks in 8bpc mode as well since sinks must fall back to 8bpc whenever GCP isn't received for some time. BSpec says we should disable GCP after disabling the port, so do that as well. v2: s/intel_set_gcp_infoframe/intel_hdmi_set_gcp_infoframe/ Rebased due to crtc->config changes Signed-off-by:Ander Conselvan de Oliveira <conselvan2@gmail.com> Signed-off-by:

According to bspec the DDI PHY vswing scale value is "don't care" in case the scale enable bit [27] is clear. But this doesn't seem to be correct. The scale value seems to also matter if the scale mode bit [26] is set. So both bit 26 and 27 depend on the value. Setting the scale value to 0 while either bit is set results in a failed modeset on HDMI (sink reports no signal). After reset the scale value is 0x98, but according to the spec we have to program it to 0x9a. So for consistency program it always to 0x9a regardless of the scale enable bit. Signed-off-by:

We can operate with DPLL0 off with CDCLK backed by the 24Mhz reference clock, and that's a supported configuration. Don't warn when notice DPLL0 is off then. We still have a separate warn at boot if cdclk is disabled (because we don't currently try to handle the case (that shouldn't happen on SKL as far as I know) where we boot with display not initialized.

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.

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

drm-amdkfd-next-2015-06-03: - Add the H/W debugger support module, including new IOCTLs to: - register/unregister a process as a debugged process - Set address watch-point in the debugged process's GPU kernel - Do a wave control operation in the debugged process's waves See the commit messages for more details on the available operations. The debugged process can only perform debug operation on itself. It is blocked by the amdkfd+H/W from performing operations on other processes's waves or GPU kernels. The blocking is done by setting the VMID and PASID of the debugged process in the packets that are sent to the CP with the debug instructions. - Add support for static user-mode queues. These queues are regular queues, but because they belong to the debugged process, we need to make sure the CP doesn't preempt them during a debug operation. Therefore, we mark them as static for the CP ignore them during preemption. - Support killing all the waves when a process is terminated. This is needed in case a process is terminated but we can't UNMAP its queues (can occur due to several reasons). In that case, the CP could be stuck unless we kill all its waves. This function is *very* important as it provides the kernel a high level of control over the GPU. The reason we didn't upstream this function so far, is because it is implemented using the H/W debugger module functions, so we had to wait until we can upstream the H/W debugger module. - Replace declaration of bitmap from unsigned long to standard DECLARE_BITMAP * tag 'drm-amdkfd-next-2015-06-03' of git://people.freedesktop.org/~gabbayo/linux: drm/amdkfd: Enforce kill all waves on process termination drm/radeon: Add ATC VMID<-->PASID functions to kfd->kgd drm/amdkfd: Implement address watch debugger IOCTL drm/amdkfd: Implement wave control debugger IOCTL drm/amdkfd: Implement (un)register debugger IOCTLs drm/amdkfd: Add address watch operation to debugger drm/amdkfd: Add wave control operation to debugger drm/amdkfd: Add skeleton H/W debugger module support drm/amdkfd: Add static user-mode queues support drm/amdkfd: add H/W debugger IOCTL set definitions drm/radeon: Add H/W debugger kfd->kgd functions drm/amdkfd: Use DECLARE_BITMAP

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. Signed-off-by:

This commit makes sure that on process termination, after we're destroying all the active queues, we're killing all the existing wave front of the current process. By doing this we're making sure that if any of the CUs were blocked by infinite loop we're enforcing it to end the shader explicitly. Signed-off-by:

This patch adds support for static user-mode queues in QCM. Queues which are designated as static can NOT be preempted by the CP microcode when it is executing its scheduling algorithm. This is needed for supporting the debugger feature, because we can't allow the CP to preempt queues which are currently being debugged. The number of queues that can be designated as static is limited by the number of HQDs (Hardware Queue Descriptors). Signed-off-by:

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:
