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.

From cffb4add03b1fc83026b06dc3664279cfbf70155 Mon Sep 17 00:00:00 2001
From: Jim Paris <jim@jtan.com>
Date: Tue, 6 Jan 2009 11:32:10 +0000
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.

Subject: [PATCH] powerpc/ps3: Move ps3_mm_add_memory to device_initcall
Change the PS3 hotplug memory routine ps3_mm_add_memory() from
a core_initcall to a device_initcall.
core_initcall routines run before the powerpc topology_init()
startup routine, which is a subsys_initcall, resulting in
failure of ps3_mm_add_memory() when CONFIG_NUMA=y. When
ps3_mm_add_memory() fails the system will boot with just the
128 MiB of boot memory

Subject: [PATCH] ps3/block: Replace mtd/ps3vram by block/ps3vram
Convert the PS3 Video RAM Storage Driver from a MTD driver to a plain block

Convert the PS3 Video RAM Storage Driver from an MTD driver to a plain block

The ps3vram driver exposes unused video RAM on the PS3 as a block device

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
