2018-09-13drm/i915: Fix a potential integer overflow with framebuffers extending past ↵Ville Syrjälä
4 GiB If we have framebuffers that are >= 4GiB in size we will overflow the fb size check in intel_fill_fb_info(). Currently that is only possible with NV12 and CCS as offsets[1] may be anything between 0 and 0xffffffff. offsets[0] is currently required to be 0 so we can't hit the overflow with any single plane format (thanks to max fb size of 8kx8k and max stride of 32 KiB). In the future we may allow almost any framebuffer to exceed 4GiB in size so we really should fix the overflow. Not that the overflow is particularly dangerous. It's mostly just a sanity check against insane userspace. The display engine can't write to memory anyway so I suppose in the worst case we might anger the hw by attempting scanout past the end of the ggtt, or we might scan out some data that we're not supposed to see from other parts of the ggtt. Note that triggering this overflow depends on the driver aligning the fb height to the next tile boundary to push the calculated size above 4GiB. With linear buffers the effective tile height is one so that never happens, and the core already has a check for 32bit overflow of offsets[]+pitches[]*height. v2: Drop the unnecessary cast (Chris) Testcase: igt/kms_big_fb/x-tiled-addfb-size-offset-overflow Testcase: igt/kms_big_fb/y-tiled-addfb-size-offset-overflow Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20180912180443.28649-1-ville.syrjala@linux.intel.com

Also, ucma_put_ctx() may use ctx after ucma_free_ctx() too. ucma_close() should call ucma_put_ctx() too which tests the refcnt and waits for the last one releasing it. The similar pattern is already used by ucma_destroy_id().

2018-09-13ALSA: hda - Enable runtime PM only for discrete GPUTakashi Iwai
The recent change of vga_switcheroo allowed the runtime PM for HD-audio on AMD GPUs, but this also resulted in a regression. When the HD-audio controller driver gets runtime-suspended, HD-audio link is turned off, and the hotplug notification is ignored. This leads to the inconsistent audio state (the connection isn't notified and ELD is ignored). The best fix would be to implement the proper ELD notification via the audio component, but it's still not ready. As a quick workaround, this patch adds the check of runtime_idle and allows the runtime suspend only when the vga_switcheroo is bound with discrete GPU. That is, a system with a single GPU and APU would be again without runtime PM to keep the HD-audio link for the hotplug notification and ELD read out. Also, the codec->auto_runtime_pm flag is set only for the discrete GPU at the time GPU gets bound via vga_switcheroo (i.e. only dGPU is forcibly runtime-PM enabled), so that APU can still get the ELD notification. For identifying which GPU is bound, a new vga_switcheroo client callback, gpu_bound, is implemented. The vga_switcheroo simply calls this when GPU is bound, and tells whether it's dGPU or APU.

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.

We can remove the update-via-batch-buffer code path, which is basically an effective duplicate of update-via-context-image path, if we notice that after we have idled the GPU, we can update the context image even of the kernel context directly. (Update-via-batch-buffer path existed only to solve the problem of how to update the kernel context image.) Only additional thing needed is to activate the edited configuration by sending one empty request down the pipe. This accomplishes context restore of the updated kernel context and so the OA configuration gets written out to it's control registers.

Currently, the CCP driver assumes that the SEV command issued to the PSP will always return (i.e. it will never hang). But recently, firmware bugs have shown that a command can hang. Since of the SEV commands are used in probe routines, this can cause boot hangs and/or loss of virtualization capabilities. To protect against firmware bugs, add a timeout in the SEV command execution flow. If a command does not complete within the specified timeout then return -ETIMEOUT and stop the driver from executing any further commands since the state of the SEV firmware is unknown.

2018-09-12RDMA/uverbs: Atomically flush and mark closed the comp event queueSteve Wise
Currently a uverbs completion event queue is flushed of events in ib_uverbs_comp_event_close() with the queue spinlock held and then released. Yet setting ev_queue->is_closed is not set until later in uverbs_hot_unplug_completion_event_file(). In between the time ib_uverbs_comp_event_close() releases the lock and uverbs_hot_unplug_completion_event_file() acquires the lock, a completion event can arrive and be inserted into the event queue by ib_uverbs_comp_handler(). This can cause a "double add" list_add warning or crash depending on the kernel configuration, or a memory leak because the event is never dequeued since the queue is already closed down. So add setting ev_queue->is_closed = 1 to ib_uverbs_comp_event_close().

2018-09-12drm/amd: Add DM DMCU supportDavid Francis
DMCU (Display Microcontroller Unit) is a GPU chip involved in eDP features like Adaptive Backlight Modulation and Panel Self Refresh. DC is already fully equipped to initialize DMCU as long as the firmware is loaded. At the moment only the raven firmware is available. A single .bin file is loaded by the kernel's loading mechanism and split into two ucodes according to the header. DMCU is optional, so if the firmware is not found, no error or warning is raised.
