Some drm_fourcc functions also already operate on the drm_format_info pointer for that reason, so the API is quite inconsistent there. Let's follow the latter pattern and remove the extra lookup while being a bit more consistent. In order to be extra consistent, also rename that function to drm_format_info_plane_cpp and to a static function in the header to match the current policy.

Most drivers are using this function while having access to the entry already, which means that we will perform an unnecessary lookup. Removing the call to these functions is therefore more efficient. Some drivers will not have access to that entry in the function, but in this case the overhead is minimal (we just have to call drm_format_info() to perform the lookup) and we can even avoid multiple, inefficient lookups in some places that need multiple fields from the drm_format_info structure. This is amplified by the fact that most of the time the callers will have to retrieve both the vsub and hsub fields, meaning that they would perform twice the lookup.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 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).
