* ASoC: core: Better support for idle_bias_off suspend ignoresMark Brown2012-01-311-0/+11
| | | | | | | | | | | | | | | | | If an idle_bias_off device is in any state other than off then it is still active for some reason (typically a low power function such as accessory detection). This wasn't an issue when the feature was implemented as we always went to _ON for any active function, subsequent power improvements have changed things. With the modern way of doing things we should overhaul the infrastructure to allow devices to explicitly take references for these functions but that's a much more invasive change and will require driver updates to deploy, this will bring the framework into line with the existing driver set before we do that work.

* ASoC: wm2000: Fix use-after-free - don't release_firmware() twice on errorJesper Juhl2012-01-241-18/+13
| | | | | | | | | | | | | | | | | | | | | | | | | In wm2000_i2c_probe(), if we take the true branch in " ret = snd_soc_register_codec(&i2c->dev, &soc_codec_dev_wm2000, NULL, 0); if (ret != 0) goto err_fw; " then we'll release_firmware(fw) at the 'err_fw' label. But we've already done that just a few lines above. That's a use-after-free bug. This patch restructures the code so that we always call release_firmware(fw) before leaving the function, but only ever call it once. This means that we have to initialize 'fw' to NULL since some paths may now end up calling it without having called request_firmware(), but since request_firmware() deals gracefully with NULL pointers, we are fine if we just NULL initialize it.

* ASoC: mxs: Fix mxs-saif timeoutFabio Estevam2012-01-201-0/+5
| | | | | | | | | | | | | | | | | | | | | | | On a mx28evk board the following errors happens on mxs-sgtl5000 probe: [ 0.660000] saif0_clk_set_rate: divider writing timeout [ 0.670000] mxs-sgtl5000: probe of mxs-sgtl5000.0 failed with error -110 [ 0.670000] ALSA device list: [ 0.680000] No soundcards found. This timeout happens because clk_set_rate will result in writing to the DIV bits of register HW_CLKCTRL_SAIF0 with the saif clock gated (CLKGATE bit set to one). MX28 Reference states the following about CLKGATE: "The DIV field can change ONLY when this clock gate bit field is low." So call clk_prepare_enable prior to clk_set_rate to fix this problem. After this change the mxs-saif driver can be correctly probed and audio is functional.

| | | * | x86, tsc: Fix SMI induced variation in quick_pit_calibrate()Linus Torvalds2012-01-171-8/+6

PIT MSB transition has happened somewhere during SMI execution. c. returned from SMI and we noted down the 'tsc', saw the pit MSB change now and exited the loop to calculate 'deltatsc'. Instead of noting the TSC at the MSB transition, we are way off because of the SMI. And as the SMI happened between the pit_verify_msb() and before the 'tsc' is recorded in the for loop, 'delattsc' (d1/d2 in quick_pit_calibrate()) will be small and quick_pit_calibrate() will not notice this error. Depending on whether SMI disturbance happens while computing d1 or d2, we will see the TSC calibrated value smaller or bigger than the expected value. As a result, in a cluster we were seeing a variation of approximately +/- 20MHz in the calibrated values, resulting in NTP failures. [ As far as the SMI source is concerned, this is a periodic SMI that gets disabled after ACPI is enabled by the OS. But the TSC calibration happens before the ACPI is enabled. ] To address this, change pit_expect_msb() so that - the 'tsc' is the TSC in between the two reads that read the MSB change from the PIT (same as before) - the 'delta' is the difference in TSC from *before* the MSB changed to *after* the MSB changed. Now the delta is twice as big as before (it covers four PIT accesses, roughly 4us) and quick_pit_calibrate() will loop a bit longer to get the calibrated value with in the 500ppm precision. As the delta (d1/d2) covers four PIT accesses, actual calibrated result might be closer to 250ppm precision. As the loop now takes longer to stabilize, double MAX_QUICK_PIT_MS to 50. SMI disturbance will showup as much larger delta's and the loop will take longer than usual for the result to be with in the accepted precision. Or will fallback to slow PIT calibration if it takes more than 50msec. Also while we are at this, remove the calibration correction that aims to get the result to the middle of the error bars. We really don't know which direction to correct into, so remove it.

The bug is a non-atomic update of a memory-mapped register. When hardware message delivery and software message acknowledge occur simultaneously the pending message acknowledge for the arriving message may be lost. This causes the sender's message status to stay busy. Part of the workaround is to not acknowledge a completed message until it is verified that no other message is actually using the resource that is mistakenly recorded in the completed message. Part of the workaround is to test for long elapsed time in such a busy condition, then handle it by using a spare sending descriptor. The stay-busy condition is eventually timed out by hardware, and then the original sending descriptor can be re-used. Most of that logic change is in keeping track of the current descriptor and the state of the spares. The occurrences of the workaround are added to the BAU statistics.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tracepoints are disabled for tainted modules, which is usually because the module is either proprietary or was forced, and we don't want either of them using kernel tracepoints. But, a module can also be tainted by being in the staging directory or compiled out of tree. Either is fine for use with tracepoints, no need to punish them. I found this out when I noticed that my sample trace event module, when done out of tree, stopped working.

The 'X' stands for: Memory addressed by the DS:rSI register pair (for example, MOVS, CMPS, OUTS, or LODS). On the other hand 'Y' means (also see the ae byte entry for SCASB): Memory addressed by the ES:rDI register pair (for example, MOVS, CMPS, INS, STOS, or SCAS).
