edac: i5000_edac critical fix panic out of bounds

2010-04-01T22:55:32+00:00

commit 118f3e1afd5534c15f9701f33514186cfc841a27 upstream. EDAC MC0: INTERNAL ERROR: channel-b out of range (4 >= 4) Kernel panic - not syncing: EDAC MC0: Uncorrected Error (XEN) Domain 0 crashed: 'noreboot' set - not rebooting. This happens because FERR_NF_FBD bit 28 is not updated on i5000. Due to that, both bits 28 and 29 may be equal to one, returning channel = 3. As this value is invalid, EDAC core generates the panic.

amd64_edac: print debug statements only on error

2009-08-04T10:10:06+00:00

Add forgotten return calls for the successful cases. Signed-off-by: Doug Thompson Signed-off-by: Borislav Petkov

amd64_edac: fix ECC checking

2009-08-03T14:54:20+00:00

On the good path of BIOS enabled ECC and no override, the value returned is 1 by omission and thus is deemed failing by the probe-function. Allow proper module initialization by clearing the retval explicitly. Signed-off-by: Doug Thompson Signed-off-by: Borislav Petkov

edac: x38 fix mchbar high register addr

2009-07-30T02:10:34+00:00

Intel X38 MCHBAR is a 64bits register, base from 0x48, so its higher base is 0x4C. Signed-off-by: Lu Zhihe Signed-off-by: Doug Thompson Cc: [2.6.30.x] Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

edac: add DDR3 memory type for MPC85xx EDAC

2009-07-01T01:55:59+00:00

Since some new MPC85xx SOCs support DDR3 memory now, so add DDR3 memory type for MPC85xx EDAC. Signed-off-by: Yang Shi Cc: Doug Thompson Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

amd64_edac: misc small cleanups

2009-06-26T11:06:41+00:00

- cleanup debug calls - shorten function names - cleanup error exit paths Signed-off-by: Borislav Petkov

amd64_edac: fix ecc_enable_override handling

2009-06-26T11:06:41+00:00

amd64_check_ecc_enabled() returns non-zero status when ECC checking/correcting is disabled and this fails further loading of the driver even when 'ecc_enable_override' boot param is used. Fix that by clearing return status in that case. Signed-off-by: Borislav Petkov

amd64_edac: check only ECC bit in amd64_determine_edac_cap

2009-06-26T11:06:40+00:00

Checking whether the machine is using ECC enabled DRAM is done through testing the DimmEccEn bit in the DRAM Cfg Low register (F2x[1,0]90). Do that instead of testing all bits from the DimmEccEn upwards. Also, remove mci->edac_cap assignment and use value returned from amd64_determine_edac_cap(). Signed-off-by: Borislav Petkov
