2014-05-26powerpc/e6500: hw tablewalk: fix recursive tlb lock on cpu 0Scott Wood
Commit e2929e1e0ab910995090ce0714beab75618db694 "powerpc/e6500: Make TLB lock recursive" introduced a bug whereby cpu 0 uses the same value for "lock held" as is used to indicate that the lock is free. This means that cpu 1 can acquire the lock whenever it wants, regardless of whether cpu 0 has it locked, which in turn means we can get duplicate TLB entries. Add one to the CPU value to ensure we do not use zero as a "lock held" value.

2014-05-21powerpc/e6500: hw tablewalk: clear TID in kernel indirect entriesScott Wood
Previously TID was being cleared before the tlbsx, but not after. This can lead to a multiway hit between a TLB entry with TID=0 (previously inserted when PID=0) and a TLB entry with TID!=0 that matches PID. This can theoretically result in undefined behavior, though we probably get lucky due to the details of the overlap. It also results in the inability to use multihit detection to detect other conflicting TLB entries, as well as poorer TLB utilization due to duplicating kernel TLB entries. Rather than try to patch up MAS1 after tlbsx, the entire value is saved/restored as with MAS2. I observed a slight improvement in TLB miss performance with this patch applied.

Erratum A-008007 states that PVR register value is unreliable for e5500 cores (Major revision 1.0, Minor revision 2.0) which are present in T1040 Rev1.0 SoC. This workaround implementation -adds a new config option 'CONFIG_FSL_ERRATUM_A_008007' in t1040 specific defconfig files. This config option is used to make sure that changes does not impact non-T1040 platforms. -replaces mfspr(x) macro defintion to check if above erratum is defined and if x is same as SPRN_PVR, then return static value else call mfspr instruction. -Similarly replaces mfpvr() calls TODO: 1.Use some cleaner approach like reading SVR rgeister or parse device tree to check if T1040 Rev1.0 Si instead of using config option. 2.This patch only replaces current accesses of PVR register but does not restrict any new code which tries to read this.

2014-05-09powerpc/booke64: wrap tlb lock and search in htw miss with FTR_SMTLaurentiu Tudor
Virtualized environments expose a e6500 dual-threaded core as two single-threaded e6500 cores. Take advantage of this and get rid of the tlb lock and the trap-causing tlbsx in the htw miss handler by guarding with CPU_FTR_SMT, as it's already being done in the bolted tlb1 miss handler. As results below show, lmbench random memory access latency test shows an improvement of ~34%.

EP device bar address will lost when EP device in D3 state, But when system thaw out from hibernation freezen, EP bar address not be restored in thaw flow. The pci framework provide arch-specific hooks(pcibios_pm_ops) when a PCI device is doing a hibernate transition, so register fsl_pci_thaw_noirq into pcibios_pm_ops to fix this issue, the fsl_pci_thaw_noirq will call pci_restore_state() to restore EP bar address.

2014-05-07kvm: booke: clear host tlb reference flag on guest tlb invalidationBharat Bhushan
On booke, "struct tlbe_ref" contains host tlb mapping information (pfn: for guest-pfn to pfn, flags: attribute associated with this mapping) for a guest tlb entry. So when a guest creates a TLB entry then "struct tlbe_ref" is set to point to valid "pfn" and set attributes in "flags" field of the above said structure. When a guest TLB entry is invalidated then flags field of corresponding "struct tlbe_ref" is updated to point that this is no more valid, also we selectively clear some other attribute bits, example: if E500_TLB_BITMAP was set then we clear E500_TLB_BITMAP, if E500_TLB_TLB0 is set then we clear this. Ideally we should clear complete "flags" as this entry is invalid and does not have anything to re-used. The other part of the problem is that when we use the same entry again then also we do not clear (started doing or-ing etc). So far it was working because the selectively clearing mentioned above actually clears "flags" what was set during TLB mapping. But the problem starts coming when we add more attributes to this then we need to selectively clear them and which is not needed.

2014-05-05sparc64: Make sure %pil interrupts are enabled during hypervisor yield.David S. Miller
[ Upstream commit cb3042d609e30e6144024801c89be3925106752b ] In arch_cpu_idle() we must enable %pil based interrupts before potentially invoking the hypervisor cpu yield call. As per the Hypervisor API documentation for cpu_yield: Interrupts which are blocked by some mechanism other that pstate.ie (for example %pil) are not guaranteed to cause a return from this service. It seems that only first generation Niagara chips are hit by this bug. My best guess is that later chips implement this in hardware and wake up anyways from %pil events, whereas in first generation chips the yield is implemented completely in hypervisor code and requires %pil to be enabled in order to wake properly from this call.
