My various attempts at re-enabling runtime PM have failed, so just crank the clock down when V3D is idle to reduce power consumption. Signed-off-by: Eric Anholt <eric@anholt.net> drm/v3d: Plug dma_fence leak The irq_fence and done_fence are given a reference that is never released. The necessary dma_fence_put()s seem to have been deleted in error in an earlier commit. Fixes: 0b73676836b2 ("drm/v3d: Clock V3D down when not in use.") Signed-off-by: Phil Elwell <phil@raspberrypi.org> v3d_drv: Handle missing clock more gracefully Signed-off-by: popcornmix <popcornmix@gmail.com> v3d_gem: Kick the clock so firmware knows we are using firmware clock interface Setting the v3d clock to low value allows firmware to handle dvfs in case where v3d hardware is not being actively used (e.g. console use). Signed-off-by: popcornmix <popcornmix@gmail.com> drm/v3d: Switch clock setting to new api Signed-off-by: Dom Cobley <popcornmix@gmail.com> drm/v3d: Convert to new clock range API Signed-off-by: Maxime Ripard <maxime@cerno.tech> drm/v3d: Correct clock settng calls to new APIs There was a report that 6.12 kernel has lower benchmark scores than 6.6. I can confirm, and found it started with 6.8 kernel which moved some code into a new file (v3d_submit.c) and in two places the change to the clock api were missed. The effect of the bug is the v3d clock sometimes unwantedly drops to a lower rate. With this patch the benchmark scores are good again. Fixes:86963038cbSigned-off-by: Dom Cobley <popcornmix@gmail.com> drm/v3d: CPU job submissions shouldn't affect V3D GPU clock We can avoid calling the v3d_clock_up_put and v3d_clock_up_get when a job is submitted to a CPU queue. We don't need to change the V3D core frequency to run a CPU job as it is executed on the CPU. This way we avoid delaying timestamps CPU jobs by 4.5ms that is the time that it takes the firmware to increase the V3D core frequency.

Linux kernel
There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first.
In order to build the documentation, use make htmldocs or
make pdfdocs. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
