Currently, the Kbuild core manipulates header search paths in a crazy way [1]. To fix this mess, I want all Makefiles to add explicit $(srctree)/ to the search paths in the srctree. Some Makefiles are already written in that way, but not all. The goal of this work is to make the notation consistent, and finally get rid of the gross hacks. Having whitespaces after -I does not matter since commit 48f6e3cf ("kbuild: do not drop -I without parameter"). [1]: https://patchwork.kernel.org/patch/9632347/Signed-off-by:

With the previous patch drm_crtc_find will return NULL when the crtc isn't in our lease, which will then disable the plane/connector. No longer an issue since the lessor can't escape their lease terms anymore, but not quite great semantics yet either. Catch this and return -EACCES, so that at least evil test cases have a better chance of making sure the kernel works correctly. Reviewed-by:

We need this to make sure lessees can only connect their plane/connectors to crtc objects they own. And note that this is irrespective of whether the lessor is atomic or not, lessor cannot prevent lessees from enabling atomic.

If userspace doesn't enable universal planes, then we automatically add the primary and cursor planes. But for universal userspace there's no such check (and maybe we only want to give the lessee one plane, maybe not even the primary one), hence we need to check for the implied plane. v2: don't forget setcrtc ioctl. v3: Still allow disabling of the crtc in SETCRTC.

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. Signed-off-by:
