A bit a mess, since with DP/TV outputs we can't use the pipe CRC. Also, no plane CRCs, so we need to update the basic testcases. Reviewed-by:

Since we use intel_enable_rc6() now for more than just when we're enabling RC6, we'll see this message many times, and it is just confusing. As an example, calc_residency calls this function whenever poked via sysfs. This leaves the impression in dmesg that we're constantly re-enabling RC6. While at it, move the defines and description from drv.h to intel_pm.c, since these are only ever used in that code. Signed-off-by:

hw designers decided to change the CRC registers and coalesce them all into one. Otherwise nothing changed. I've opted for a new hsw_ version to grab the crc sample since hsw+1 will have the same crc registers, but different interrupt source registers. So this little helper function will come handy there. Also refactor the display error handler with a neat pipe loop. v2: Use for_each_pipe. Reviewed-by:

The drm/i915 driver wants to adjust it's own power policies using the cpu policies as a guideline (we can implicitly boost the cpus through the gpus on some platforms). To avoid a dreaded select (since a depends will leave users wondering where where their driver has gone too) add dummy functions. Reported-by:

It's better to catch such fallout early, and this way we can rely on the checking done by the drm core on fb->heigh/width at modeset time. If we ever support planar formats on intel we might want to look into a common helper to do all this, but for now this is good enough. v2: Take tiling into account, requested by Ville. v3: Fix tile height on gen2, spotted by Ville.

At least on linux sizeof(long) == sizeof(void*) and the thinking is that you can grab about as many references as there's memory. Doesn't really matter, just a bit of OCD since the fixed size data type in a pure in-kernel datastructure look off. v2: Ville asked for an overflow check since no one prevents userspace from incrementing the pin count forever. v3: s/INT/LONG/, noticed by Chris.

Assuming that all framebuffer related metadata is invariant simplifies our userspace input data checking. And current userspace always first updates the tiling of an object before creating a framebuffer with it. This allows us to upconvert a check in pin_and_fence to a WARN. In the future it should also be helpful to know which buffer objects are potential scanout targets for e.g. frontbuffer rendering tracking and similar things. Note that SNA shipped for one prerelease with code which will be broken through this patch. But users shouldn't notice since it's purely an optimization and will transparently fall back to allocating a new fb. i-g-t also had offending code (now fixed), but we don't really care about breaking the test-suite.

We look at gem state (like obj->tiling/obj->stride), we better have the relevant locks. Right now this doesn't matter much since most of these checks are a curtesy to safe buggy userspace, but I'd like to freeze the tiling once we have framebuffer objects attached. And then locking matters. Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:

This patch changes HDMI port registration order for the BayTrail platform. The story is that in kernel version 3.11 i915 supported only one HDMI port - the HDMIB port. So this port ended up being HDMI-1 in user-space. But commit '6f6005a5 drm/i915: expose HDMI connectors on port C on BYT' introduced HDMIC port support. And added HDMIC registration prior to HDMIB, so HDMIB became HDMI-2 and HDMIC became HDMI-1. Well, this is fine as far as the kernel is concerned. i915 does not give any guarantees to the numbering, and has never given them. However, this breaks wayland setup in Tizen IVI. We have only one single HDMI port on our hardware, and it is connected to HDMIB. Our configuration relies on the fact that it is HDMI-1. Well, certainly this is user-space problem which was exposed with Jesse's patch. However, there is a reason why we have to do this assumption - we use touchscreen monitors and we have to associate event devices with the monitors, and this is not easy to do dynamically, so we just have a static setup. Anyway, while the user-space setup will have to be fixed regardless, let's chane the HDMI port registration order so that HDMIB stays HDMI-1, just like it was in 3.11. Simply because there is no strong reason for changing the order in the kernel, and it'll help setups like ours in sense that we'll have more time for fixing the issue properly. Also amend the commentary which looks a bit out-of-date. Signed-off-by:

We have two once very similar functions, i915_gpu_idle() and i915_gem_idle(). The former is used as the lower level operation to flush work on the GPU, whereas the latter is the high level interface to flush the GEM bookkeeping in addition to flushing the GPU. As such i915_gem_idle() also clears out the request and activity lists and cancels the delayed work. This is what we need for unloading the driver, unfortunately we called i915_gpu_idle() instead. In the process, make sure that when cancelling the delayed work and timer, which is synchronous, that we do not hold any locks to prevent a deadlock if the work item is already waiting upon the mutex. This requires us to push the mutex down from the caller to i915_gem_idle(). v2: s/i915_gem_idle/i915_gem_suspend/ Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=70334Signed-off-by:

seq_file is not quite the right interface for these ones. We have a circular buffer with a new entry per vblank on one side and a process wanting to dequeue the CRC with a read(). It's quite racy to wait for vblank in user land and then try to read a pipe_crc file, sometimes the CRC interrupt hasn't been fired and we end up with an EOF. So, let's have the read on the pipe_crc file block until the interrupt gives us a new entry. At that point we can wake the reading process. Signed-off-by:
