[PATCH 0/5] lib: devres: Add managed helpers for write-combine setup

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

 



Add devm_arch_phys_wc_add() and devm_arch_io_reserve_memtype_wc() for
automatic cleanup of writecombine setup.

Several DRM drivers use the non-managed functions for setting their
framebuffer memory to write-combine access. Convert ast, mgag200 and
vboxvideo. Remove rsp clean-up code form drivers.

Tested on mgag200 hardware.
