EDAC, mce_amd: Get rid of local var in amd_filter_mce()

2017-08-21T15:59:38+00:00

... and use the macro for that. No functionality change. Signed-off-by: Borislav Petkov

EDAC, mce_amd: Get rid of most struct cpuinfo_x86 uses

2017-08-21T15:54:57+00:00

struct mce.cpuid contains CPUID(1).EAX which contains family, model and stepping and thus has enough information for our purposes. Thus get rid of some external dependencies which are not really needed. No functionality change. Signed-off-by: Borislav Petkov

EDAC, mce_amd: Rename decode_smca_errors() to decode_smca_error()

2017-08-21T15:44:09+00:00

Singular fits better because it decodes a single error. No functionality change. Signed-off-by: Borislav Petkov

EDAC: Make device_type const

2017-08-20T11:12:32+00:00

Make these const as they are only stored in the type field of a device structure, which is const. Done using Coccinelle. Signed-off-by: Bhumika Goyal Cc: linux-edac Link: http://lkml.kernel.org/r/1503130946-2854-2-git-send-email-bhumirks@gmail.com Signed-off-by: Borislav Petkov

EDAC, pnd2: Properly toggle hidden state for P2SB PCI device

Properly handle hidden state of P2SB PCI device (DEV:D, FUN:0) for Apollo Lake. Signed-off-by: Qiuxu Zhuo Cc: Tony Luck Cc: linux-edac Link: http://lkml.kernel.org/r/20170814154905.21707-1-qiuxu.zhuo@intel.com Signed-off-by: Borislav Petkov

EDAC, pnd2: Conditionally unhide/hide the P2SB PCI device to read BAR

2017-08-19T08:47:24+00:00

On Deverton server, the P2SB PCI device (DEV:1F, FUN:1) is used by multiple device drivers. If it's hidden by some device driver (e.g. with the i801 I2C driver, the commit 9424693035a5 ("i2c: i801: Create iTCO device on newer Intel PCHs") unconditionally hid the P2SB PCI device wrongly) it will make the pnd2_edac driver read out an invalid BAR value of 0xffffffff and then fail on ioremap(). Therefore, store the presence state of P2SB PCI device before unhiding it for reading BAR and restore the presence state after reading BAR.

EDAC, pnd2: Mask off the lower four bits of a BAR

2017-08-19T08:33:30+00:00

Bit[0] of BAR is always zero. Bit[2:1] and bit[3] of BAR contain the information of 'type' and the 'prefetchable' accordingly. Therefore, mask the lower four bits to retrieve the actual base address of a BAR.

EDAC, thunderx: Fix error handling path in thunderx_lmc_probe()

EDAC, pnd2: Build in a minimal sideband driver for Apollo Lake

2017-08-04T03:58:23+00:00

I've been waing a long time for the generic sideband driver to appear. Patience has run out, so include the minimum here to just read registers.
