Subject: [PATCH] mtd/ps3vram: Add ps3vram driver for accessing video RAM as MTD
|
|
|
|
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.
