Jordan Crouse authored
The a6xx GPU powers on in secure mode which restricts what memory it can write to. To get out of secure mode the GPU driver can write to REG_A6XX_RBBM_SECVID_TRUST_CNTL but on targets that are "secure" that register region is blocked and writes will cause the system to go down. For those targets we need to execute a special sequence that involves loadinga special shader that clears the GPU registers and use a PM4 sequence to pull the GPU out of secure. Add support for loading the zap shader and executing the secure sequence. For targets that do not support SCM or the specific SCM sequence this should fail and we would fall back to writing the register.

First loop does copy_from_user() without the table lock held and just stores the handle. Second loop looks up buffer objects with the table_lock held without potentially blocking or faulting. This lets us clean up a bunch of custom, non-faulting copy_from_user() code. Signed-off-by: Kristian H. Kristensen <hoegsberg@chromium.org> Signed-off-by: Rob Clark <robdclark@chromium.org>

We use a llist and a worker to delay the object cleanup. This avoids taking mmap_sem and struct_mutex in the wrong order when calling drm_gem_object_put_unlocked() from drm_gem_mmap().

Currently if the GMU resume function fails all we try to do is clear the BOOT_SLUMBER oob which usually times out and ends up in a cycle of death. If the resume function fails at any point remove any RPMh votes that might have been added and try to shut down the GMU hardware cleanly.

Now that the GX domain is sorted we can wire up a working GMU reset. IF a GMU hang was detected then try to forcefully shut down the GMU in the power down sequence which should ensure that it can recover normally on the next power up.

99.999% of the time during normal operation the GMU is responsible for power and clock control on the GX domain and the CPU remains blissfully unaware. However, there is one situation where the CPU needs to get involved: The power sequencing rules dictate that the GX needs to be turned off before the CX so that the CX can be turned on before the GX during power up. During normal operation when the CPU is taking down the CX domain a stop command is sent to the GMU which turns off the GX domain and then the CPU handles the CX domain. But if the GMU happened to be unresponsive while the GX domain was left then the CPU will need to step in and turn off the GX domain before resetting the CX and rebooting the GMU. This unfortunately means that the CPU needs to be marginally aware of the GX domain even though it is expected to usually keep its hands off. To support this we create a semi-disabled GX power domain that does nothing to the hardware on power up but tries to shut it down normally on power down. In this method the reference counting is correct and we can step in with the pm_runtime_put() at the right time during the failure path. This patch sets up the connection to the GX power domain and does the magic to "enable" and disable it at the right points.

The GMU should have two power domains defined: "cx" and "gx". "cx" is the actual power domain for the device and "gx" will be attached at runtime to manage reference counting on the GPU device in case of a GMU crash.

The GMU code currently has some misguided code to try to work around a hardware quirk that requires the power domains on the GPU be collapsed in a certain order.

Add the capability to query information from a submit queue. The first available parameter is for querying the number of GPU faults (hangs) that can be attributed to the queue. This is useful for implementing context robustness. A user context can regularly query the number of faults to see if it is responsible for any and if so it can invalidate itself. This is also helpful for testing by confirming to the user driver if a particular command stream caused a fault (or not as the case may be).

The frame_busy mask is used in frame_done event handling, which is not invoked for async commits. So an async commit will leave the frame_busy mask populated after it completes and future commits will start with the busy mask incorrect. This showed up on disable after cursor move. I was hitting the "this should not happen" comment in the frame event worker since frame_busy was set, we queued the event, but there were no frames pending (since async also doesn't set that).

In the case of an async/cursor update, we don't wait for the frame_done event, which means handle_frame_done is never called, and the frame_done watchdog isn't canceled. Currently, this results in a frame_done timeout every time the cursor moves without a synchronous frame following it up before the timeout expires. Since we don't wait for frame_done, and don't handle it, we shouldn't modify the watchdog.

There exists a bunch of confusion as to what the actual units of frame_done is: - The definition states it's in # of frames - CRTC treats it like it's ms - frame_done_timeout comment thinks it's Hz, but it stores ms - frame_done timer is setup such that it _should_ be in frames, but the timeout is super long So this patch tries to interpret what the driver really wants. I've de-centralized the #define since the consumers are expecting different units. For crtc, we just use 60ms since that's what it was doing before. Perhaps we could get fancy and scale with vrefresh, but that's for another time. For encoder, fix the comments and rename frame_done_timeout so it's obvious what the units are. In practice, frame_done_timeout is really just checked against 0 || !0, which I guess is why the units being wrong didn't matter. I've also dropped the timeout from the previous 60 frames to 5. That seems like more than enough time to give up on a frame, and my guess is that no one intended for the timeout to _actually_ be 60 frames.

Currently the IOMMU code calls pm_runtime_get/put on the GPU or display device before doing a IOMMU operation. This was because usually the IOMMU driver didn't do power control of its own and since the hardware used the same clocks and power as the respective multimedia device it was a easy way to make sure that the power was available. Now two things have changed. First, the SMMU devices can do their own power control and more important bringing up the a6xx GPU isn't as easy as turning on some clocks. To bring the GPU up we need the GMU which itself needs the IOMMU so we have a chicken and egg problem. Luckily this is easily fixed by removing the pm_runtime calls from the functions and letting the device link to the IOMMU device handle the magic.

The pages backing the GEM objects are kept pinned in place as long as they are alive, so they must not be allocated from the MOVABLE zone. Blocking page migration for too long will cause the VM subsystem headaches and will outright break CMA, as a few pinned pages in CMA will lead to failure to find the required large contiguous regions.

This reverts commit fa946356. Per Linus Walleij: Dear ARM SoC maintainers, can you please revert this patch. It was the wrong solution to the wrong problem, and I must have acted in stress. Andrey fixed the real bug in a proper way in these commits: commit e5545c94 "gpio: of: Check propname before applying "cs-gpios" quirks" commit 7ce40277 "gpio: of: Check for "spi-cs-high" in child instead of parent node" Signed-off-by: Olof Johansson <olof@lixom.net>
