ps3: Replace direct file operations by callback

2009-06-15T06:47:26+00:00

Currently the FLASH database is updated by the kernel using file operations,
meant for userspace only. While this works for us because copy_{from,to}_user()
on powerpc can handle kernel pointers, this is unportable and a bad example.
Replace the file operations by callbacks, registered by the ps3flash driver.

Create a real RTC driver for PS3, and unhook the deprecated
ppc_md.[gs]et_rtc_time.

powerpc/ps3: Use dma_addr_t down through the stack

2009-01-16T05:15:11+00:00

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

mtd/ps3vram: Add modalias support to the ps3vram driver

mtd/ps3vram: Add ps3vram driver for accessing video RAM as MTD

2009-01-08T05:25:14+00:00

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 support

2008-12-16T03:39:33+00:00

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 mutex

2008-11-19T05:03:54+00:00

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.
