Export msm_gem_pin_pages_locked() and acquire the reservation lock directly in GEM pin callback. Same for unpin. Prepares for further changes. Dma-buf locking semantics require callers to hold the buffer's reservation lock when invoking the pin and unpin callbacks. Prepare msm accordingly by pushing locking out of the implementation. A follow-up patch will fix locking for all GEM code at once. Signed-off-by:

Rename msm_gem_pin_pages_locked() to msm_gem_get_pages_locked(). The function doesn't pin any pages, but only acquires them. Renaming the function makes the old name available. Signed-off-by:

Debugfs isn't always available in production builds that try to squeeze every single byte out of the kernel image, but we still need a way to toggle the timestamp and cycle counter registers so that jobs can be profiled for fdinfo's drm engine and cycle calculations. Drop the debugfs knob and replace it with a sysfs file that accomplishes the same functionality, and document its ABI in a separate file. Signed-off-by:

panthor_device_resume/suspend() are only compiled when CONFIG_PM is enabled but panthro_drv.c doesn't use the pm_ptr() macro to conditionally discard resume/suspend assignments, which causes undefined symbol errors at link time when !PM. We could fix that by using pm_ptr(), but supporting the !PM case makes little sense (the whole point of these embedded GPUs is to be low power, so proper PM is a basic requirement in that case). So let's just enforce the presence of CONFIG_PM with a Kconfig dependency instead. If someone needs to relax this dependency, it can be done in a follow-up. Reported-by:
