-Subject: [PATCH] powerpc/ps3: Replace the flip_ctl logic in ps3av and ps3fb by a mutex
-
-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.

-
-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.

-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.

-Subject: [PATCH] ps3/block: Replace mtd/ps3vram by block/ps3vram
-
-Convert the PS3 Video RAM Storage Driver from an MTD driver to a plain block
-device driver.
-
-The ps3vram driver exposes unused video RAM on the PS3 as a block device
-suitable for storage or swap. Fast data transfer is achieved using a local
-cache in system RAM and DMA transfers via the GPU.
-
-The new driver is ca. 50% faster for reading, and ca. 10% for writing.

-Subject: net/ps3_gelic: Fix RX DMA restart
-
-Fix the condition where PS3 network RX hangs when no network
-TX is occuring by calling gelic_card_enable_rxdmac() during
-RX_DMA_CHAIN_END event processing.
-
-The gelic hardware automatically clears its RX_DMA_EN flag when
-it detects an RX_DMA_CHAIN_END event. In its processing of
-RX_DMA_CHAIN_END the gelic driver is required to set RX_DMA_EN
-(with a call to gelic_card_enable_rxdmac()) to restart RX DMA
-transfers. The existing gelic driver code does not set
-RX_DMA_EN directly in its processing of the RX_DMA_CHAIN_END
-event, but uses a flag variable card->rx_dma_restart_required
-to schedule the setting of RX_DMA_EN until next inside the
-interrupt handler.
-
-It seems this delayed setting of RX_DMA_EN causes the hang since
-the next RX interrupt after the RX_DMA_CHAIN_END event where
-RX_DMA_EN is scheduled to be set will not occur since RX_DMA_EN
-was not set. In the case were network TX is occuring, RX_DMA_EN
-is set in the next TX interrupt and RX processing continues.
