Push getting the reference for the encoders' power domains into the encoder get_power_domains() hook instead of doing this from the caller. This way the encoder can store away the corresponding wakerefs. This fixes the DSI encoder disabling, which didn't release these power references it acquired during HW state readout. Note that longtime ownership for the corresponding wakerefs can be thus acquired / released in two ways. Nevertheless there is always only one owner for them: After HW readout (booting/system resume): - encoder->get_power_domains() acquires - encoder->disable*() releases After a modeset (calling intel_atomic_commit()): - encoder->enable*() acquires - encoder->disable*() releases * can be any of the encoder enable/disable hooks. v2: - Check that the DSI io_wakerefs are unset both during encoder HW readout and enabling.

While transitioning to having better clarity between the modules, it's desirable to have the function name prefixes reflect the module. Functions in intel_foo.c should be prefixed intel_foo_. Expose only one CDCLK init/uninit function from intel_cdclk.c instead of one per platform. Obviously this adds one "unnecessary" if ladder within the entry points. However it should be considered more of a CDCLK implementation detail how this is done per platform, instead of exposing the fact. In other words, abstract the CDCLK module better. No functional changes. Reviewed-by:

It used to be handy that we only had a couple of headers, but over time intel_drv.h has become unwieldy. Extract declarations to a separate header file corresponding to the implementation module, clarifying the modularity of the driver. Ensure the new header is self-contained, and do so with minimal further includes, using forward declarations as needed. Include the new header only where needed, and sort the modified include directives while at it and as needed. No functional changes. Reviewed-by:

The only bpc information in pipe registers for BXT/GLK DSI is the PIPEMISC dither bpc. Let's try to use that to read out pipe_bpp on these platforms. However, I'm not sure if this will be correctly populated by the GOP since bspec suggests it's only needed if dithering is actually enabled. If not I guess we'll have to go one step further and extract pipe_bpp from the DSI pixel format when dithering is disabled.

Haswell+ require many power wells to probe the current HW display state. Under the wakeref tracking scheme, we want each owner to store and release the wakeref they use, so we can identify callers that have leaked their wakeref. For hsw_get_pipe_config, this means we have to keep the array of all wakerefs as it current acquires its power wells piecemeal and releases them en masse. By tracking these wakerefs, we should be able to eliminate a lot of noise from the runtime-pm debug logs. Signed-off-by:

Chris Wilson authored
When we introduced preemption, we chose to keep it disabled for gen8 as supporting preemption inside GPGPU user batches required various w/a in userspace. Since then, the desire to preempt long queues of requests between batches (e.g. within busywaiting semaphores) has grown. So allow arbitration within the busywaits and between requests, but disable arbitration within user batches so that we can preempt between requests and not risk breaking GPGPU. However, since this preemption is much coarser and doesn't interfere with userspace, we decline to include it amongst the scheduler capabilities. (This is also required for us to skip over the preemption selftests that expect to be able to preempt user batches.) Michal suggested that we could perhaps allow preemption inside gen8 userspace batches if we can satisfy ourselves that the default preemption settings are viable with existing userspace (principally OpenCL which already should carry any known workaround). We could then merge the two code paths back into one, even dropping the artifical has-preemption device feature flag.

During request construction, we take the timeline->mutex to ensure exclusive access to the ringbuffer (for command emission) and the timeline itself (for command ordering). The timeline->mutex should not be dropped by callers until we release it in i915_request_add(). lockdep provides a pin/unpin lock facility to detect accidental unlocks inside critical sections, so put it to use for request construction.
