Re: [PATCH v4 0/5] ppc, fbdev: Clean up fbdev mmap helper

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


Ping for a review.

I'd like to get at least the first two patches into the DRM git tree. The PPC patches could later be merged through another tree.

Best regards

Clean up and rename fb_pgprotect() to work without struct file. Then
refactor the implementation for PowerPC. This change has been discussed
at [1] in the context of refactoring fbdev's mmap code.

The first two patches update fbdev and replace fbdev's fb_pgprotect()
with pgprot_framebuffer() on all architectures. The new helper's stream-
lined interface enables more refactoring within fbdev's mmap

Patches 3 to 5 adapt PowerPC's internal interfaces to provide
phys_mem_access_prot() that works without struct file. Neither the
architecture code or fbdev helpers need the parameter.

	* fix commit message (Christophe)
	* rename fb_pgrotect() to pgprot_framebuffer() (Arnd)
	* reorder patches to simplify merging (Michael)
