Subject: [PATCH v3 0/6] powerpc: AMP support for 47x
Date: Wed, 9 Feb 2011 17:08:07 -0600 [thread overview]
Message-ID: <1297292893-30241-1-git-send-email-shaggy@linux.vnet.ibm.com> (raw)
These patches add Asynchonous MultiProcessing support for the 47x chipset.
This allows independent OS instances to run on separate cores.
v3:
1. switched from using compatible string to boolean "cooperative-partition"
2. fixed missing type in boot wrapper
3. fixed check for unspecified memory range in boot wrapper
4. Cleaned up the dts files
v2:
1. Replace ugly hack in boot wrapper with generic solution
Dave Kleikamp (6):
powerpc: Move udbg_early_init() after early_init_devtree()
powerpc/44x: allow override to hard-coded uart address
powerpc/47x: allow kernel to be loaded in higher physical memory
powerpc/44x: don't use tlbivax on AMP systems
powerpc/44x: boot wrapper: allow kernel to load into non-zero address
powerpc/476: Create a dts files for two 476 AMP instances under ISS
