2023-10-12fbdev: Avoid file argument in fb_pgprotect()Thomas Zimmermann1-1/+6
Only PowerPC's fb_pgprotect() needs the file argument, although the implementation in either phys_mem_access_prot() or pci_phys_mem_access_prot() does not use it. Pass NULL to the internal helper in preparation of further updates. A later patch will remove the file parameter from fb_pgprotect(). While at it, replace the shift operation with PHYS_PFN(). v5: * state function names in commit description (Javier) Suggested-by: Christophe Leroy <[email protected]> Signed-off-by: Thomas Zimmermann <[email protected]> Reviewed-by: Arnd Bergmann <[email protected]> Reviewed-by: Javier Martinez Canillas <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

2023-10-09drm/bridge: samsung-dsim: update PLL reference clockMichael Tretter2-2/+27
The PLL requires a clock frequency in a certain platform-dependent range after the pre-divider. The reference clock for the PLL may change due to changes to it's parent clock. Thus, the frequency may be out of range or unsuited for generating the high speed clock for MIPI DSI. Try to keep the pre-devider small, and set the reference clock close to the upper limit before recalculating the PLL configuration. Use a divider with a power of two for the reference clock as this seems to work best in my tests.

2023-10-09drm/bridge: samsung-dsim: reread ref clock before configuring PLLMichael Tretter2-7/+10
The PLL reference clock may change at runtime when its parent clock changes. For example, this may happen on the i.MX8M Nano if the reference clock is a child of the Video PLL. If the pixel clock changes, this may propagate to the Video PLL and as a side effect change the reference clock. Thus, reading the clock rate during probe is not sufficient to correctly configure the PLL for the expected hs clock. Read the actual rate of the reference clock before calculating the PLL configuration parameters. Note that the "samsung,pll-clock-frequency" is always preferred and PLL reference clock is only read from the clock tree if that device tree property is not set.

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() is renamed to .remove(). samsung_dsim_remove() returned 0 unconditionally. Make it return void instead to convert the two related platform drivers to use .remove_new().

2023-10-04drm/panfrost: Implement generic DRM object RSS reporting functionAdrián Larumbe3-0/+21
BO's RSS is updated every time new pages are allocated on demand and mapped for the object at GPU page fault's IRQ handler, but only for heap buffers. The reason this is unnecessary for non-heap buffers is that they are mapped onto the GPU's VA space and backed by physical memory in their entirety at BO creation time. This calculation is unnecessary for imported PRIME objects, since heap buffers cannot be exported by our driver, and the actual BO RSS size is the one reported in its attached dmabuf structure.

2023-10-04drm/drm_file: Add DRM obj's RSS reporting function for fdinfoAdrián Larumbe2-3/+14
Some BO's might be mapped onto physical memory chunkwise and on demand, like Panfrost's tiler heap. In this case, even though the drm_gem_shmem_object page array might already be allocated, only a very small fraction of the BO is currently backed by system memory, but drm_show_memory_stats will then proceed to add its entire virtual size to the file's total resident size regardless. This led to very unrealistic RSS sizes being reckoned for Panfrost, where said tiler heap buffer is initially allocated with a virtual size of 128 MiB, but only a small part of it will eventually be backed by system memory after successive GPU page faults. Provide a new DRM object generic function that would allow drivers to return a more accurate RSS and purgeable sizes for their BOs.
