I have been able to test on stm32f4 with drm/kms drivers which is calling dma_alloc_coherent and modetest doing mmap and it is working fine. tested-by: Benjamin Gaignard <[email protected]> > > @Christoph, in case you decide to queue PATCH 1/2, can you put it > before "ARM: NOMMU: Introduce dma operations for noMMU", so transition > to the new dma operations won't break bisectability. > > [1] git://git.infradead.org/users/hch/dma-mapping.git for-next > [2] https://www.spinics.net/lists/arm-kernel/msg590587.html > > Cc: Steven Miao <[email protected]> > Cc: Geert Uytterhoeven <[email protected]> > Cc: Michal Simek <[email protected]> > Cc: Yoshinori Sato <[email protected]> > Cc: Rich Felker <[email protected]> > Cc: Chris Zankel <[email protected]> > Cc: Max Filippov <[email protected]> > > Thanks! > > Vladimir Murzin (2): > drivers: dma-mapping: allow dma_common_mmap() for NOMMU > fixup: ARM: NOMMU: Introduce dma operations for noMMU > > arch/arm/mm/dma-mapping-nommu.c | 18 ------------------ > arch/blackfin/Kconfig | 1 + > arch/m32r/Kconfig | 1 + > arch/m68k/Kconfig | 1 + > arch/microblaze/Kconfig | 1 + > arch/sh/Kconfig | 1 + > arch/xtensa/Kconfig | 1 + > drivers/base/dma-mapping.c | 4 ++-- > 8 files changed, 8 insertions(+), 20 deletions(-) > > -- > 2.0.0 > -- Benjamin Gaignard Graphic Study Group Linaro.org │ Open source software for ARM SoCs Follow Linaro: Facebook | Twitter | Blog
