2010-03-03sh: establish PMB mappings for NUMA nodes.Paul Mundt
In the case of NUMA emulation when in range PPNs are being used for secondary nodes, we need to make sure that the PMB has a mapping for it before setting up the pgdat. This prevents the MMU from resetting. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-12-09sh: NUMA lmb fixesMagnus Damm
This patch updates the NUMA version of setup_memory() with UMA code changes and also modifies the last argument to lmb_alloc_base() to use an address instead of pfn. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-12-09sh: fix size calculation for NUMA node 0Magnus Damm
Fix the NUMA size calculation for node 0. Do the same as the UMA version of setup_memory() and use address instead of pfn when calculating the size. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-11-04sh: Make sure indexes are positiveRoel Kluin
The indexes are signed, make sure they are not negative when we read array elements. Signed-off-by: Roel Kluin <roel.kluin@gmail.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-07-05sh: Use bootmem ontop of lmb for NUMAMatt Fleming
Like the UP case, use lmb as the foundation of memory resource management on NUMA. Signed-off-by: Matt Fleming <matt@console-pimps.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-07-24mm: move bootmem descriptors definition to a single placeJohannes Weiner
There are a lot of places that define either a single bootmem descriptor or an array of them. Use only one central array with MAX_NUMNODES items instead.

2008-05-08sh: add memory resources to /proc/iomemMagnus Damm
Add physical memory resources such as System RAM, Kernel code/data/bss and reserved crash dump area to /proc/iomem. Same strategy as on x86. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-02-07Introduce flags for reserve_bootmem()Bernhard Walle
This patchset adds a flags variable to reserve_bootmem() and uses the BOOTMEM_EXCLUSIVE flag in crashkernel reservation code to detect collisions between crashkernel area and already used memory. This patch: Change the reserve_bootmem() function to accept a new flag BOOTMEM_EXCLUSIVE. If that flag is set, the function returns with -EBUSY if the memory already has been reserved in the past. This is to avoid conflicts. Because that code runs before SMP initialisation, there's no race condition inside reserve_bootmem_core().

2007-06-08sh: Support for multiple nodes.Paul Mundt
This adds basic support for multiple nodes on SH machines. This is primarily useful for boards with many different memory blocks that are otherwise unused (SH7722/SH7785 URAM and so forth). Signed-off-by: Paul Mundt <lethal@linux-sh.org>
