* MIPS: Remove unused task_struct.trap_no field.David Daney2010-08-051-2/+0

* MIPS: kprobe: Add support.David Daney2010-08-053-0/+97
| | | | | | | | | | | | | | | | | | | | This patch is based on previous work by Sony and Himanshu Chauhan. I have done some cleanup and implemented JProbes and KRETPROBES. The KRETPROBES part is pretty much copied verbatim from powerpc. A possible future enhance might be to factor out the common code.

* MIPS: Loongson: Oprofile: add a new do_perfcnt_IRQ()Wu Zhangjin2010-08-051-0/+8
| | | | | | | | | | | | | | On FuLoong-2F IP6 is shared by the performance counter overflow interrupt and the Bonito northbridge interrupt. To reduce overhead only call do_IRQ() when oprofile is enabled to reduce overhead. This patch adds an inline function do_perfcnt_IRQ() to hide the #if's , which can be shared by the other Loongson machines, i.e. gdium.

* MIPS: PowerTV: Use O(1) algorthm for phys_to_dma/dma_to_physDavid VomLehn2010-08-052-48/+125
| | | | | | | | | | | | | | | | | | | | | | | | Replace phys_to_dma()/dma_to_phys() looping algorithm with an O(1) algorithm The approach taken is inspired by the sparse memory implementation: take a certain number of high-order bits off the address them, use this as an index into a table containing an offset to the desired address and add it to the original value. There is a table for mapping physical addresses to DMA addresses and another one for the reverse mapping. The table sizes depend on how fine-grained the mappings need to be; Coarser granularity less to smaller tables. On a processor with 32-bit physical and DMA addresses, with 4 MIB granularity, memory usage is two 2048-byte arrays. Each 32-byte cache line thus covers 64 MiB of address space. Also, renames phys_to_bus() to phys_to_dma() and bus_to_phys() to dma_to_phys() to align with kernel usage.

* MIPS: BCM47xx: Add NVRAM support devicesWaldemar Brodkorb2010-07-051-0/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When trying to netboot a Linksys WRT54GS WLAN router, the bootup fails, because of following error message: ... [ 0.424000] b44: b44.c:v2.0 [ 0.424000] b44: Invalid MAC address found in EEPROM [ 0.432000] b44 ssb0:1: Problem fetching invariants of chip,aborting [ 0.436000] b44: probe of ssb0:1 failed with error -22 ... The router uses a CFE bootloader, but most of the needed environment variables for network card initialization, are not available from CFE via printenv and even though not via cfe_getenv(). The required environment variables are saved in a special partition in flash memory. The attached patch implement nvram_getenv and enables bootup via NFS root on my router. Most of the patch is extracted from the OpenWrt subversion repository and stripped down and cleaned up to just fix this issue. [Ralf: sorted out header file inclusions. Lots of unneded headers and such that should have been included.] Signed-off-by: Waldemar Brodkorb <wbx@openadk.org> Reviewed-by: Phil Sutter <phil@nwl.cc> To: linux-mips@linux-mips.org Cc: Hauke Mehrtens <hauke@hauke-m.de> Patchwork: http://patchwork.linux-mips.org/patch/1359/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
