+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.

+Change the PS3 hotplug memory routine ps3_mm_add_memory() from

+
+core_initcall routines run before the powerpc topology_init()

+failure of ps3_mm_add_memory() when CONFIG_NUMA=y. When
+ps3_mm_add_memory() fails the system will boot with just the

-Notes:
-
-The MTD-based PS3 Video RAM Storage Driver was integrated into the mainline
-kernel in 2.6.29-rc1.
-
-Ideally, we think it would be best if the existing MTD-based ps3vram driver
-would be replaced by the new block-based ps3vram driver before 2.6.29 is
-released. This would relieve the burden of supporting two different swap space
-schemes on PS3 (swap on /dev/mtdblock0 vs. /dev/ps3vram) from the distro
-maintainer's shoulders, as in that case there would never have been a stable
-kernel version containing the MTD-based ps3vram driver.
-
-Changes since previous submission (Wed, 4 Mar 2009 14:57:20 +0100 (CET)):
- - Use blk_queue_make_request() to get rid of the thread
- - Add a mutex (cfr. the old driver), as ps3vram_make_request() may be called
- concurrently
- TO DO (after 2.6.29): use a spinlock and a list to queue requests while the
- driver is busy
- - Remove the old MTD-based ps3vram driver and rename ps3vram-ng to ps3vram
- - Make PS3_VRAM depend on FB_PS3=y and m for now
- ps3vram relies on ps3fb being initialized first. The easiest way to do this
- is by making ps3vram modular, and ps3fb builtin
- - Remove the dependency on ps3fb_videomemory.size
- The loop to reduce ddr_size until it succeeds does the right thing anyway,
- and a few MiB of DDR RAM are reserved by the hypervisor
- - lv1 return codes can be int
- - Correct a few debug annotations
