drm/etnaviv: bump HW job limit to 4

2018-03-22T10:08:48+00:00

The current limit of 2 leads to some GPU idle times, as the usual IRQ latency leads to up to 3 jobs getting signaled at once with some standard workloads. A larger HW job limit might lead to slightly worse QoS, but we accept that to not sacrifice GPU throughput in the common case. Signed-off-by: Lucas Stach

drm/etnaviv: etnaviv_sched: Staticize functions when possible

2018-03-09T11:25:01+00:00

etnaviv_sched_dependency() and etnaviv_sched_run_job() are only used in this file, so make them static. This fixes the following sparse warnings: drivers/gpu/drm/etnaviv/etnaviv_sched.c:30:18: warning: symbol 'etnaviv_sched_dependency' was not declared. Should it be static? drivers/gpu/drm/etnaviv/etnaviv_sched.c:81:18: warning: symbol 'etnaviv_sched_run_job' was not declared. Should it be static?

drm/etnaviv: add PTA handling to MMUv2

2018-03-09T11:23:48+00:00

The Page Table Array is a new first level structure above the MTLB availabale on GPUs with the security feature. Use the PTa to set up the MMU when the security related states are handled by the kernel driver. Signed-off-by: Lucas Stach

drm/etnaviv: add function to load the initial PTA state

2018-03-09T11:22:38+00:00

On GPUs with the security feature the MTLB config is stored in the PTA. Add a function to trigger the initial PTA load through the FE. Signed-off-by: Lucas Stach

drm/etnaviv: handle security states

2018-03-09T11:22:38+00:00

GPUs with support for the security features need some additional setup to get the frontend started. Signed-off-by: Lucas Stach

drm/etnaviv: add security handling mode enum

2018-03-09T11:22:37+00:00

With the introduction of GPU security we have 3 different modes of GPU operation: - GPU core doesn't have security features -> no handling required - the security related states are handled by the kernel driver - the security related states are handled by a TrustZone application Add a enum to differentiate between the different operation modes.

drm/etnaviv: add hardware database

2018-03-09T11:22:37+00:00

New versions of the Vivante kernel driver don't trust the hardware feature bits anymore, but use an internal hardware database. This also includes more feature fields than are available in hardware. As we can't trust the hardware feature bits to be correct anymore, we need to replicate the HWDB in etanviv. For now only the GC7000L as found on the i.MX8M is supported. Signed-off-by: Lucas Stach

drm/etnaviv: add more minor features fields

2018-03-09T11:22:36+00:00

Newer GPU cores added yet more feature bits. Make room for them and let userspace query them. Signed-off-by: Lucas Stach

drm/etnaviv: update hardware headers from rnndb

2018-03-09T11:22:36+00:00

Update the state HI and common header from rnndb commit 8478eef32fd9 (rnndb: document secure GPU reset bit). Signed-off-by: Lucas Stach

drm/etnaviv: add support for slave interface clock

2018-03-09T11:22:35+00:00

The slave interface clock is a clock input found on newer cores to gate the register interface. For now we simply ungate it when the GPU is in active state. Signed-off-by: Lucas Stach
