* i7core_edac: Add a code to probe Xeon 55xx busMauro Carvalho Chehab2010-05-10
| | | | | | | | | | | | | | | | | This code changes the detection procedure of i7core_edac. Instead of directly probing for MC registers, it probes for another register found on Nehalem. If found, it tries to pick the first MC PCI BUS. This should work fine with Xeon 35xx, but, on Xeon 55xx, this is at bus 254 and 255 that are not properly detected by the non-legacy PCI methods. The new detection code scans specifically at buses 254 and 255 for the Xeon 55xx devices. This code has not tested yet. After working, a change at the code will be needed, since the i7core is not yet ready for working with 2 sets of MC. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* pci: Add a probing code that seeks for an specific busAristeu Rozanski2010-05-10
| | | | | | | | | This patch adds a probing code that seeks for an specific pci bus. It still needs testing, but it is hoped that this will help to identify the memory controller with Xeon 55xx series.

* i7core_edac: Adds write unlock to MC registersMauro Carvalho Chehab2010-05-10
| | | | | | | | | | | | | | | | | The public Intel Xeon 5500 volume 2 datasheet describes, on page 53, session 2.6.7 a register that can lock/unlock Memory Controller the configuration register, called MC_CFG_CONTROL. Adds support for it in the hope that software error injection would work. With my tests with Xeon 35xx, there's still something missing. With a program that does sequencial bit writes at dev 0.0, sometimes, it produces error injection, after unblocking the MC_CFG_CONTROL (and, sometimes, it just locks my testing machine). I'll try later to discover by trial and error what's the register that solves this issue on Xeon 35xx. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* i7core_edac: Add edac_mce glueMauro Carvalho Chehab2010-05-10
| | | | | | | | | | | | | | Adds a glue code to allow i7core to work with mcelog. With the glue, i7core registers itself on edac_mce. At mce, when an error is detected, it calls all registered drivers (in this case, i7core), for EDAC error handling. TODO: It currently just prints the MCE error log using about the same format as mce panic messages. The error message should be enhanced with mcelog userspace info and converted into the proper EDAC format, to feed the EDAC error counts. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

* i7core_edac: Add a memory check routine, based on device 3 function 4Mauro Carvalho Chehab2010-05-10
| | | | | | | | | | | | | | | | This function appears only on Xeon 5500 datasheet. Yet, testing with a Xeon 3503 showed that this is also implemented on other Nehalem processors. At the first read, MC_TEST_ERR_RCV1 and MC_TEST_ERR_RCV0 can contain any value. Modify CE error logic to update the error count only after the second read. An alternative approach would be to do a write at rcv0 and rcv1 registers, but it seemed better to keep they untouched, since BIOS might eventually assume that they are exclusive for their usage.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | On low memory boxes or those with highmem, kernel can OOM before the background reclaims inodes via xfssyncd. Add a shrinker to run inode reclaim so that it inode reclaim is expedited when memory is low. This is more complex than it needs to be because the VM folk don't want a context added to the shrinker infrastructure. Hence we need to add a global list of XFS mount structures so the shrinker can traverse them. Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Christoph Hellwig <hch@lst.de>

| * | | powerpc/fsl-cpm: Configure clock correctly for SCCWolfgang Ocker2010-04-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some board setup functions call cpm1_clk_setup() or cmp2_clk_setup() to configure the clock source. If CPM_CLK_RTX has been used for the parameter mode, the clock has been configured only for TX but not for RX. With this patch CPM_CLK_RTX configures the clock for both directions correctly.
