* powerpc/ps3: Use dma_addr_t down through the stackStephen Rothwell2009-01-161-4/+4
| | | | | | | | | | | | | | Push the dma_addr_t type usage all the way down to where the actual values are manipulated. Now that u64 is "unsigned long long", this removes warnings like: arch/powerpc/platforms/ps3/system-bus.c:532: warning: passing argument 4 of 'ps3_dma_map' from incompatible pointer type arch/powerpc/platforms/ps3/system-bus.c:649: warning: passing argument 4 of 'ps3_dma_map' from incompatible pointer type Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Acked-by: Geoff Levand <geoffrey.levand@am.sony.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

* mtd/ps3vram: Add ps3vram driver for accessing video RAM as MTDJim Paris2009-01-081-0/+1
| | | | | | | | | | | | Add ps3vram driver, which exposes unused video RAM on the PS3 as a MTD device suitable for storage or swap. Fast data transfer is achieved using a local cache in system RAM and DMA transfers via the GPU.

* powerpc/ps3: Add sub-match id modalias supportGeert Uytterhoeven2008-12-161-27/+26
| | | | | | | | | | | | | commit 059e4938f8b060b10c4352e6c45739473bc73267 ("powerpc/ps3: Add a sub-match id to ps3_system_bus") forgot to update the module alias support: - Add the sub-match ids to the module aliases, so udev can distinguish between different types of sub-devices. - Rename PS3_MODULE_ALIAS_GRAPHICS to PS3_MODULE_ALIAS_GPU_FB, as ps3fb binds to the "FB" sub-device.

* powerpc/ps3: Replace the flip_ctl logic in ps3av and ps3fb by a mutexGeert Uytterhoeven2008-11-191-0/+3
| | | | | | | | | | | Introduce ps3_gpu_mutex to synchronizes GPU-related operations, like: - invoking the L1GPU_CONTEXT_ATTRIBUTE_FB_BLIT command using the lv1_gpu_context_attribute() hypervisor call, - handling the PS3AV_CID_AVB_PARAM packet in the PS3 A/V Settings driver.

* powerpc: Move include files to arch/powerpc/include/asmStephen Rothwell2008-08-041-0/+519
from include/asm-powerpc. This is the result of a mkdir arch/powerpc/include/asm git mv include/asm-powerpc/* arch/powerpc/include/asm Followed by a few documentation/comment fixups and a couple of places where <asm-powepc/...> was being used explicitly. Of the latter only one was outside the arch code and it is a driver only built for powerpc. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
