2011-03-17smp_call_function_many: handle concurrent clearing of maskMilton Miller1-3/+10
Mike Galbraith reported finding a lockup ("perma-spin bug") where the cpumask passed to smp_call_function_many was cleared by other cpu(s) while a cpu was preparing its call_data block, resulting in no cpu to clear the last ref and unlock the block. Having cpus clear their bit asynchronously could be useful on a mask of cpus that might have a translation context, or cpus that need a push to complete an rcu window. Instead of adding a BUG_ON and requiring yet another cpumask copy, just detect the race and handle it. Note: arch_send_call_function_ipi_mask must still handle an empty cpumask because the data block is globally visible before the that arch callback is made. And (obviously) there are no guarantees to which cpus are notified if the mask is changed during the call; only cpus that were online and had their mask bit set during the whole call are guaranteed to be called.

2011-03-17call_function_many: add missing orderingMilton Miller1-13/+33
Paul McKenney's review pointed out two problems with the barriers in the 2.6.38 update to the smp call function many code. First, a barrier that would force the func and info members of data to be visible before their consumption in the interrupt handler was missing. This can be solved by adding a smp_wmb between setting the func and info members and setting setting the cpumask; this will pair with the existing and required smp_rmb ordering the cpumask read before the read of refs. This placement avoids the need a second smp_rmb in the interrupt handler which would be executed on each of the N cpus executing the call request. (I was thinking this barrier was present but was not). Second, the previous write to refs (establishing the zero that we the interrupt handler was testing from all cpus) was performed by a third party cpu. This would invoke transitivity which, as a recient or concurrent addition to memory-barriers.txt now explicitly states, would require a full smp_mb(). However, we know the cpumask will only be set by one cpu (the data owner) and any preivous iteration of the mask would have cleared by the reading cpu. By redundantly writing refs to 0 on the owning cpu before the smp_wmb, the write to refs will follow the same path as the writes that set the cpumask, which in turn allows us to keep the barrier in the interrupt handler a smp_rmb instead of promoting it to a smp_mb (which will be be executed by N cpus for each of the possible M elements on the list). I moved and expanded the comment about our (ab)use of the rcu list primitives for the concurrent walk earlier into this function. I considered moving the first two paragraphs to the queue list head and lock, but felt it would have been too disconected from the code.

2011-03-17call_function_many: fix list delete vs add raceMilton Miller1-7/+13
Peter pointed out there was nothing preventing the list_del_rcu in smp_call_function_interrupt from running before the list_add_rcu in smp_call_function_many. Fix this by not setting refs until we have gotten the lock for the list. Take advantage of the wmb in list_add_rcu to save an explicit additional one. I tried to force this race with a udelay before the lock & list_add and by mixing all 64 online cpus with just 3 random cpus in the mask, but was unsuccessful. Still, inspection shows a valid race, and the fix is a extension of the existing protection window in the current code.

RPC task RPC_TASK_QUEUED bit is set must be checked before trying to wake up task rpc_killall_tasks() because task->tk_waitqueue can not be set (equal to NULL). Also, as Trond Myklebust mentioned, such approach (instead of checking tk_waitqueue to NULL) allows us to "optimise away the call to rpc_wake_up_queued_task() altogether for those tasks that aren't queued".

Remove the channel interleave select bit properly. See F2x110[DctSelIntLvAddr] for details. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-03-17amd64_edac: Correct node interleaving removalBorislav Petkov1-4/+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>
2011-03-17amd64_edac: Add support for interleaved region swappingBorislav Petkov2-0/+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>
2011-03-17amd64_edac: Unify get_error_addressBorislav Petkov2-15/+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>
2011-03-17amd64_edac: Simplify decoding pathBorislav Petkov3-65/+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>
2011-03-17amd64_edac: Adjust channel counting to F15hBorislav Petkov1-7/+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>
2011-03-17amd64_edac: Cleanup old defines cruftBorislav Petkov2-76/+22
Remove unused defines, drop family names from define names. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-03-17amd64_edac: Cleanup NBSH cruftBorislav Petkov3-27/+8
Remove reporting of errors with UC bit set - this is done by the MCE decoding code anyway and this driver deals with DRAM ECC errors only. UC (NB uncorrectable error) doesn't necessarily mean it is a DRAM error. Remove unused macros while at it. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-03-17amd64_edac: Cleanup NBCFG handlingBorislav Petkov2-30/+24
The fact whether we are chipkill capable or not does not have any bearing when computing the channel index on a ganged DCT configuration so remove that. Also, simplify debug statements. Finally, remove old error injection leftovers, while at it. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
