In order to support performance counters in a sane way we need to provide a method to sync the GPU with the CPU. The GPU can process multpile command buffers/events per irq. With the help of a 'sync point' we can trigger an event and stop the GPU/FE immediately. When the CPU is done with is processing it simply needs to restart the FE and the GPU will process the command stream. Changes from v1 -> v2: - process sync point with a work item to keep irq as fast as possible Changes from v4 -> v5: - renamed pmrs_* to sync_point_* - call event_free(..) in sync_point_worker(..)

Sadly we can not read any registers via command stream so we need to extend the drm_etnaviv_gem_submit struct with performance monitor requests. Those requests gets process before or after the actual submitted command stream. The Vivante kernel driver has a special ioctl to read all perfmon registers at once and return it. Changes from v1 -> v2: - use a 16 bit value for signals - fix padding issues Signed-off-by: Christian Gmeiner <christian.gmeiner@gmail.com> Signed-off-by: Lucas Stach <l.stach@pengutronix.de>

Make it possible that userspace can query all performance domains and its signals. This information is needed to sample those signals via submit ioctl. At the moment no performance domain is available. Changes from v1 -> v2: - use a 16 bit value for signals - fix padding issues - add id member to domain and signal struct Changes v4 -> v5 - provide for each pipe an own set of pm domains Signed-off-by: Christian Gmeiner <christian.gmeiner@gmail.com> Signed-off-by: Lucas Stach <l.stach@pengutronix.de>

This makes it possible to allocate multiple events under the event spinlock. This change is needed to support 'sync'-points. Changes v2 -> v3: - wait for the completion of all events - use 10sec timeout regardless of the number of events - removed validation if there are enough free events - fixed return value evaluation of event_alloc(..) in etnaviv_gpu_submit(..)

The reset path wants to initialize the clock control register regardless of the DYNAMIC_FREQUENCY_SCALING feature, so don't call clock update, but explicitly load the register. Also disabling of the debug registers is moved into the reset function, so we always get to the same state after a GPU reset. This means the clock update function should not touch the bits already set in the clock control register, but instead only update the scaling bits.

Using the IOMMU API to manage the internal GPU MMU has been an historical accident and it keeps getting in the way, as well as entangling the driver with the inner workings of the IOMMU subsystem. Clean this up by removing the usage of iommu_domain, which is the last piece linking etnaviv to the IOMMU subsystem. Signed-off-by: Lucas Stach <l.stach@pengutronix.de>

It wasn't protecting anything, as the single word writes used to set up or tear down a translation are already inherently atomic, so the spinlock is pure overhead.

Commit 5620a0d1 ("firmware: delete in-kernel firmware") removed the entire firmware directory. Unfortunately it thereby also removed the support for built-in firmware. This restores the ability to build firmware directly into the kernel by pruning the original Makefile to the necessary minimum. The default for EXTRA_FIRMWARE_DIR is now the standard directory /lib/firmware/.

The driver doesn't support events from address families other than IPv4 and IPv6, so ignore them. Otherwise, we risk queueing a work item before it's initialized. This can happen in case a VRF is configured when MROUTE_MULTIPLE_TABLES is enabled, as the VRF driver will try to add an l3mdev rule for the IPMR family.
