2012-02-16powerpc/perf: power_pmu_start restores incorrect values, breaking frequency ↵Anton Blanchard
events perf on POWER stopped working after commit e050e3f0a71b (perf: Fix broken interrupt rate throttling). That patch exposed a bug in the POWER perf_events code. Since the PMCs count upwards and take an exception when the top bit is set, we want to write 0x80000000 - left in power_pmu_start. We were instead programming in left which effectively disables the counter until we eventually hit 0x80000000. This could take seconds or longer. With the patch applied I get the expected number of samples: SAMPLE events: 9948 Signed-off-by: Anton Blanchard <anton@samba.org> Acked-by: Paul Mackerras <paulus@samba.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: <stable@kernel.org>

2012-02-16powerpc: Disable interrupts early in Program CheckBenjamin Herrenschmidt
Program Check exceptions are the result of WARNs, BUGs, some type of breakpoints, kprobe, and other illegal instructions. We want interrupts (and thus preemption) to remain disabled while doing the initial stage of testing the reason and branching off to a debugger or kprobe, so we are still on the original CPU which makes debugging easier in various cases. This is how the code was intended, hence the local_irq_enable() right in the middle of program_check_exception(). However, the assembly exception prologue for that exception was incorrectly marked as enabling interrupts, which defeats that (and records a redundant enable with lockdep).

2012-02-16powerpc: Fix kernel log of oops/panic instruction dumpIra Snyder
A kernel oops/panic prints an instruction dump showing several instructions before and after the instruction which caused the oops/panic. The code intended that the faulting instruction be enclosed in angle brackets, however a bug caused the faulting instruction to be interpreted by printk() as the message log level. To fix this, the KERN_CONT log level is added before the actual text of the printed message. === Before the patch === [ 1081.587266] Instruction dump: [ 1081.590236] 7c000110 7c0000f8 5400077c 552907f6 7d290378 992b0003 4e800020 38000001 [ 1081.598034] 3d20c03a 9009a114 7c0004ac 39200000 [ 1081.602500] 4e800020 3803ffd0 2b800009 <4>[ 1081.587266] Instruction dump: <4>[ 1081.590236] 7c000110 7c0000f8 5400077c 552907f6 7d290378 992b0003 4e800020 38000001 <4>[ 1081.598034] 3d20c03a 9009a114 7c0004ac 39200000 <98090000>[ 1081.602500] 4e800020 3803ffd0 2b800009 === After the patch === [ 51.385216] Instruction dump: [ 51.388186] 7c000110 7c0000f8 5400077c 552907f6 7d290378 992b0003 4e800020 38000001 [ 51.395986] 3d20c03a 9009a114 7c0004ac 39200000 <98090000> 4e800020 3803ffd0 2b800009 <4>[ 51.385216] Instruction dump: <4>[ 51.388186] 7c000110 7c0000f8 5400077c 552907f6 7d290378 992b0003 4e800020 38000001 <4>[ 51.395986] 3d20c03a 9009a114 7c0004ac 39200000 <98090000> 4e800020 3803ffd0 2b800009 Signed-off-by: Ira W.

2012-02-16crypto: sha512 - use standard ror64()Alexey Dobriyan
Use standard ror64() instead of hand-written. There is no standard ror64, so create it. The difference is shift value being "unsigned int" instead of uint64_t (for which there is no reason). gcc starts to emit native ROR instructions which it doesn't do for some reason currently. This should make the code faster. Patch survives in-tree crypto test and ping flood with hmac(sha512) on.

2012-02-15drm/i915: do not enable RC6p on Sandy BridgeEugeni Dodonov
With base on latest findings, RC6p seems to be respondible for RC6-related issues on Sandy Bridge platform. To work-around those issues, the previous solution was to completely disable RC6 on Sandy Bridge for the past few releases, even if plain RC6 was not giving any issues. What this patch does is preventing RC6p from being enabled on Sandy Bridge even if users enable RC6 via a kernel parameter. So it won't change the defaults in any way, but will ensure that if users do enable RC6 manually it won't break their machines by enabling this extra state. Proper fix for this (enabling specific RC6 states according to the GPU generation) were proposed for the -next kernel, but we are too late in the release process now to pick such changes.

2012-02-16sfc: Add SR-IOV back-end support for SFC9000 familyBen Hutchings
On the SFC9000 family, each port has 1024 Virtual Interfaces (VIs), each with an RX queue, a TX queue, an event queue and a mailbox register. These may be assigned to up to 127 SR-IOV virtual functions per port, with up to 64 VIs per VF. We allocate an extra channel (IRQ and event queue only) to receive requests from VF drivers. There is a per-port limit of 4 concurrent RX queue flushes, and queue flushes may be initiated by the MC in response to a Function Level Reset (FLR) of a VF. Therefore, when SR-IOV is in use, we submit all flush requests via the MC. The RSS indirection table is shared with VFs, so the number of RX queues used in the PF is limited to the number of VIs per VF. This is almost entirely the work of Steve Hodgson, formerly shodgson@solarflare.com. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
2012-02-16sfc: Allocate SRAM between buffer table and descriptor caches at init timeBen Hutchings

2012-02-16sfc: Disable flow control during flushesSteve Hodgson
The TX DMA engine issues upstream read requests when there is room in the TX FIFO for the completion. However, the fetches for the rest of the packet might be delayed by any back pressure. Since a flush must wait for an EOP, the entire flush may be delayed by back pressure. Mitigate this by disabling flow control before the flushes are started. Since PF and VF flushes run in parallel introduce fc_disable, a reference count of the number of flushes outstanding. The same principle could be applied to Falcon, but that would bring with it its own testing. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
2012-02-16sfc: Generalise event generation to cover VF-owned event queuesBen Hutchings
For SR-IOV we will need to send events to event queues that belong to VFs serviced by other drivers. Change the parameters of efx_generate_event() to allow this and declare it extern. While we're at it, remove the existing declaration under the wrong name efx_nic_generate_event(). Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

2012-02-16sfc: Leave interrupts and event queues enabled whenever we canBen Hutchings
When SR-IOV is enabled we may receive FLR (Function-Level Reset) events, associated queue flush events and requests from VF drivers at any time. Therefore we need to keep event queues and interrupts enabled whenever possible. Currently we stop interrupt-driven event processing before flushing RX and TX queues; efx_nic_flush_queues() then polls event queues for flush events and discards any others it finds. Change it to work with the regular event handling functions. Currently efx_start_channel() fills RX queues synchronously when a device is brought up. This could now race with NAPI, so change it to send fill events. This was almost entirely written by Steve Hodgson, formerly shodgson@solarflare.com.

2012-02-16sfc: Correct MAC filter bitfield definitionsBen Hutchings
The RMFT_DEST_MAC and TMFT_SRC_MAC register fields were previously documented as 44 bits wide, whereas a MAC address has 48 bits. Thankfully the hardware uses the correct width and the driver has used separate definitions that divide each of these into 32-bit and 16-bit fields.

2012-02-16sfc: Add support for TX MAC filtersBen Hutchings

2012-02-16sfc: Add support for configuring RX unicast/multicast default filtersBen Hutchings

Currently we leave these set to the default values (RSS with base queue number of 0). Allow them to be reconfigured to select a single RX queue. These default filters are programmed through the FILTER_CTL register, but we represent them internally as an additional table of size 2. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

2012-02-15ARM: 7325/1: fix v7 boot with lockdep enabledRabin Vincent
Bootup with lockdep enabled has been broken on v7 since b46c0f74657d ("ARM: 7321/1: cache-v7: Disable preemption when reading CCSIDR"). This is because v7_setup (which is called very early during boot) calls v7_flush_dcache_all, and the save_and_disable_irqs added by that patch ends up attempting to call into lockdep C code (trace_hardirqs_off()) when we are in no position to execute it (no stack, MMU off). Fix this by using a notrace variant of save_and_disable_irqs. The code already uses the notrace variant of restore_irqs.
