2010-02-27MIPS: Allow the auxv's elf_platform entry to be set.David Daney2-7/+8
The userspace runtime linker uses the elf_platform to find the libraries optimized for the current CPU archecture variant. First we need to allow it to be set to something other than NULL. Follow-on patches will set some values for specific CPUs. GLIBC already does the right thing. The kernel just needs to supply good data.

Although the hardware supports a 4/8bit SD interface and the driver unconditionally advertises all hardware caps to the MMC core, not all datalines may actually be wired up. This patch introduces another field to au1xmmc platform data allowing platforms to disable certain advanced host controller features.

2010-02-27MIPS: Loongson: Cleanup the halt and poweroff actionWu Zhangjin1-2/+11
In the old source code, I have let halt and poweroff do the same action, but in reality, they have different meanings. As the manpage of shutdown shows: -r Reboot after shutdown. -H Halt action is to halt or drop into boot monitor on systems that support it. -P Halt action is to turn off the power. and in the real world, some machines(e.g. NAS) did not provide a power button and the shutdown works as reset, so, we need to provide a mechanism to let the users turn off the power safely without breaking the system, such a mechanism is "halt", which only put the system into a dead loop or a power-save mode and print some information to the screen to tell the users to turn off the power safely. $ shutdown -hH now /* loongson_halt, not turn off the power */ $ shutdown -hP now /* loongson_poweroff, work as poweroff */ Signed-off-by: Wu Zhangjin <wuzhangjin@gmail.com> Tested-by: Liu Shiwei <liushiwei@gmail.com> Cc: Liu Shiwei <liushiwei@gmail.com> Cc: linux-mips <linux-mips@linux-mips.org> Patchwork: http://patchwork.linux-mips.org/patch/883/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

Only reenable the interrupt on EOI if it is not IRQ_DISABLED. This requires that the EOI function be separate from the ENABLE function.

2010-02-27MIPS: Octeon: Use optimized memory barrier primitives.David Daney2-13/+31
In order to achieve correct synchronization semantics, the Octeon port had defined CONFIG_WEAK_REORDERING_BEYOND_LLSC. This resulted in code that looks like: sync ll ... . . . sc ... . . sync The second SYNC was redundant, but harmless. Octeon has a SYNCW instruction that acts as a write-memory-barrier (due to an erratum in some parts two SYNCW are used). It is much faster than SYNC because it imposes ordering on the writes, but doesn't otherwise stall the execution pipeline. On Octeon, SYNC stalls execution until all preceeding writes are committed to the coherent memory system. Using: syncw;syncw ll . . . sc . . Has identical semantics to the first sequence, but is much faster. The SYNCW orders the writes, and the SC will not complete successfully until the write is committed to the coherent memory system. So at the end all preceeding writes have been committed. Since Octeon does not do speculative reads, this functions as a full barrier. The patch removes CONFIG_WEAK_REORDERING_BEYOND_LLSC, and substitutes SYNCW for SYNC in write-memory-barriers.
