* amd64_edac:__amd64_set_scrub_rate(): avoid overindexing scrubrates[]Andrew Morton2012-10-281-7/+4
| | | | | | | | | | | | | | | | | | | | | | | commit 168bfeef7bba3f9784f7540b053e4ac72b769ce9 upstream. If none of the elements in scrubrates[] matches, this loop will cause __amd64_set_scrub_rate() to incorrectly use the n+1th element. As the function is designed to use the final scrubrates[] element in the case of no match, we can fix this bug by simply terminating the array search at the n-1th element. Boris: this code is fragile anyway, see here why: http://marc.info/?l=linux-kernel&m=135102834131236&w=2 It will be rewritten more robustly soonish.

* x86: Simplify code by removing a !SMP #ifdefs from 'struct cpuinfo_x86'Kevin Winchester2012-08-151-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 141168c36cdee3ff23d9c7700b0edc47cb65479f and commit 3f806e50981825fa56a7f1938f24c0680816be45 upstream. Several fields in struct cpuinfo_x86 were not defined for the !SMP case, likely to save space. However, those fields still have some meaning for UP, and keeping them allows some #ifdef removal from other files. The additional size of the UP kernel from this change is not significant enough to worry about keeping up the distinction: text data bss dec hex filename 4737168 506459 972040 6215667 5ed7f3 vmlinux.o.before 4737444 506459 972040 6215943 5ed907 vmlinux.o.after for a difference of 276 bytes for an example UP config. If someone wants those 276 bytes back badly then it should be implemented in a cleaner way.

* | x86: remove 32-bit versions of readq()/writeq()Roland Dreier2011-05-251-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The presense of a writeq() implementation on 32-bit x86 that splits the 64-bit write into two 32-bit writes turns out to break the mpt2sas driver (and in general is risky for drivers as was discussed in <http://lkml.kernel.org/r/adaab6c1h7c.fsf@cisco.com>). To fix this, revert 2c5643b1c5c7 ("x86: provide readq()/writeq() on 32-bit too") and follow-on cleanups. This unfortunately leads to pushing non-atomic definitions of readq() and write() to various x86-only drivers that in the meantime started using the definitions in the x86 version of <asm/io.h>. However as discussed exhaustively, this is actually the right thing to do, because the right way to split a 64-bit transaction is hardware dependent and therefore belongs in the hardware driver (eg mpt2sas needs a spinlock to make sure no other accesses occur in between the two halves of the access). Build tested on 32- and 64-bit x86 allmodconfig.

* | drivercore: revert addition of of_match to struct deviceGrant Likely2011-05-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit b826291c, "drivercore/dt: add a match table pointer to struct device" added an of_match pointer to struct device to cache the of_match_table entry discovered at driver match time. This was unsafe because matching is not an atomic operation with probing a driver. If two or more drivers are attempted to be matched to a driver at the same time, then the cached matching entry pointer could get overwritten. This patch reverts the of_match cache pointer and reworks all users to call of_match_device() directly instead. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

BIOS programs D18F1x[17C:140,7C:40] DRAM Base/Limit accordingly by subtracting the storage area from the DRAM limit setting.

| | | | | | | | | | | | | | | | | | | | | | | | Drop per-instance variable and compute min scrubrate dynamically. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
| * | | amd64_edac: Improve DRAM address mappingBorislav Petkov2011-03-172-70/+83
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Drop static tables which map the bits in F2x80 to a chip select size in favor of functions doing the mapping with some bit fiddling. Also, add F15 support. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
| * | | amd64_edac: Sanitize ->read_dram_ctl_registerBorislav Petkov2011-03-172-9/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This function is relevant for F10h and higher, and it has only one callsite so drop its function pointer from the low_ops struct. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
| * | | amd64_edac: Adjust sys_addr to chip select conversion routine to F15hBorislav Petkov2011-03-171-14/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | F15h sys_addr to chip select mapping is almost identical to F10h's so reuse that. Rename functions on that path accordingly. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
| * | | amd64_edac: Beef up early exit reportingBorislav Petkov2011-03-171-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add paranoid checks for the sys address before going off and decoding it. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
| * | | amd64_edac: Revamp online spare handlingBorislav Petkov2011-03-172-21/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace per-DCT macros with smarter ones, drop hack and look for the spare rank on all chip selects on a channel. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
| * | | amd64_edac: Fix channel interleave removalBorislav Petkov2011-03-171-9/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the channel interleave select bit properly. See F2x110[DctSelIntLvAddr] for details. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
| * | | amd64_edac: Correct node interleaving removalBorislav Petkov2011-03-171-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When node interleaving is enabled, a subset of the addr[14:12] bits has to be removed in order to get the normalized DCT address of the DRAM channel. The actual number of bits to remove is determined by F1x[1, 0][7C:40][IntlvEn]. Do this correctly. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
| * | | amd64_edac: Add support for interleaved region swappingBorislav Petkov2011-03-172-0/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On revC3 and revE Fam10h machines and later, non-interleaved graphics framebuffer memory under the 16G mark can be swapped with a region located at the bottom of memory so that the GPU can use the interleaved region and thus two channels. Add support for that. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
| * | | amd64_edac: Unify get_error_addressBorislav Petkov2011-03-172-15/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The address bits from MC4_STATUS differ only between K8 and the rest so no need for a per-family method. No functional change. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
| * | | amd64_edac: Simplify decoding pathBorislav Petkov2011-03-173-65/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use the struct mce directly instead of copying from it into a custom struct err_regs. No functionality change. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
| * | | amd64_edac: Adjust channel counting to F15hBorislav Petkov2011-03-171-7/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The only difference is that F10h used to sport ganged DCTs and F15h doesn't so adjust the F10h routine and reuse it. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
| * | | amd64_edac: Cleanup old defines cruftBorislav Petkov2011-03-172-76/+22
| | | | | | | | | | | | | | | | | | | | | | | | Remove unused defines, drop family names from define names. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
