ps3vram-driver and ps3vram-proc-fs

Post by zbowling »

Anyone else see these patches that Geoff is working on?

1 Subject: PS3: ps3vram driver for accessing video RAM as MTD
2
3 From: Jim Paris <[email protected]>
4
5 Add ps3vram driver, which exposes unused video RAM on the PS3 as a MTD
6 device suitable for storage or swap. Fast data transfer is achieved
7 using a local cache in system RAM and DMA transfers via the GPU.

I have... but I guess that's obvious.

Wasn't support for this blocked in FW 2.10? If so, does this mean that once his patch is complete that he will also release an updated otheros.bld file to allow this to be implemented again?

No, the ps3vram driver in geoff's ps3-linux.git works on all firmware versions.
(And otheros.bld has nothing to do with hypervisor security anyway)

Appears both on 2.6.25.4 from cl-sdk and latest 2.6.27-rc8 from Geoff's git.
On FW 2.43 and any previous everything worked ok.
