2014-11-04ahci: fix AHCI parameters not taken into accountAntoine Tenart1-6/+3
Changes into the AHCI subsystem have introduced a bug by not taking into account the force_port_map and mask_port_map parameters when using the ahci_pci_save_initial_config function. This commit fixes it by setting the internal parameters of the ahci_port_priv structure.

2014-10-27ahci: disable MSI instead of NCQ on Samsung pci-e SSDs on macbooksTejun Heo1-3/+11
Samsung pci-e SSDs on macbooks failed miserably on NCQ commands, so 67809f85d31e ("ahci: disable NCQ on Samsung pci-e SSDs on macbooks") disabled NCQ on them.

2014-10-27Revert "AHCI: Optimize single IRQ interrupt processing"Tejun Heo1-61/+13
This reverts commit 18dcf433f3ded61eb140a55e7048ec2fef79e723. IRQF_ONESHOT was missing from the conversion causing screaming interrupts problems on some setups and LKP detected measureable drop in IO performance. It looks like we'll first need to drop the threaded IRQ handling first before splitting locking.

The CSB series appears to support 64-KB DMA transfers, as tests on a machine with an SAI2 motherboard containing a Broadcom CSB5 IDE Controller (vendor and device IDs: 1166:0212) showed no problems with 64-KB DMA transfers. This problem was first discovered when attempting to install openSUSE from a DVD on a machine with an STL2 motherboard. Using the pata_serverworks module, older releases of openSUSE will not install at all due to the timeouts. Releases of openSUSE prior to 11.3 can be installed by disabling the pata_serverworks module using the brokenmodules boot parameter, which causes the serverworks module to be used instead. Recent releases of openSUSE (12.2 and later) include better error recovery and will install, though very slowly. On all openSUSE releases, the problem can be recreated on a machine containing a Broadcom OSB4 IDE Controller by mounting an install DVD and running a command similar to the following: find /mnt -type f -print | xargs cat > /dev/null The patch below corrects the problem. Similar to the other ATA drivers that do not support 64-KB DMA transfers, the patch changes the ata_port_operations qc_prep vector to point to a routine that breaks any 64-KB segment into two 32-KB segments and changes the scsi_host_template sg_tablesize element to reduce by half the number of scatter/gather elements allowed. These two changes affect only the OSB4. Signed-off-by: Scott Carter <ccscott@funsoft.com> Signed-off-by: Tejun Heo <tj@kernel.org> Cc: stable@vger.kernel.org
2014-10-07libata: Un-break ATA blacklistGeorge Spelvin1-2/+2
lib/glob.c provides a new glob_match() function, with arguments in (pattern, string) order. It replaced a private function with arguments in (string, pattern) order, but I didn't swap the call site... The result was the entire ATA blacklist was effectively disabled. The lesson for today is "I f***ed up *how* badly *how* many months ago?", er, I mean "Nobody Tests RC Kernels On Legacy Hardware". This was not a subtle break, but it made it through an entire RC cycle unreported, presumably because all the people doing testing have full-featured hardware. (FWIW, the reason for the argument swap was because fnmatch() does it that way, and for a while implementing a full fnmatch() was being considered.)

2014-10-06AHCI: Optimize single IRQ interrupt processingAlexander Gordeev1-13/+61
Split interrupt service routine into hardware context handler and threaded context handler. That allows to protect ports with individual locks rather than with a single host-wide lock and move port interrupts handling out of the hardware interrupt context. Testing was done by transferring 8GB on two hard drives in parallel using command 'dd if=/dev/sd{a,b} of=/dev/null'. With lock_stat statistics I measured access times to ata_host::lock spinlock (since interrupt handler code is fully embraced with this lock). The average lock's holdtime decreased eight times while average waittime decreased two times. Both before and after the change the transfer time is the same, while 'perf record -e cycles:k ...' shows 1%-4% CPU time spent in ahci_single_irq_intr() routine before the update and not even sampled/shown ahci_single_irq_intr() after the update.

2014-10-06AHCI: Do not read HOST_IRQ_STAT reg in multi-MSI modeAlexander Gordeev2-60/+9
As described in AHCI v1.0 specification chapter 10.6.2.2 "Multiple MSI Based Messages" generation of interrupts is not controlled through the HOST_IRQ_STAT register. Considering MMIO access is expensive remove unnecessary reading and writing of HOST_IRQ_STAT register. Further, serializing access to the host data is no longer needed and the interrupt service routine can avoid competing on the host lock.

2014-09-23ahci_xgene: Fix the error print invalid resource for APM X-Gene SoC AHCI ↵Suman Tripathi1-2/+8
SATA Host Controller driver. This patch fixes the error print invalid resource for the APM X-Gene SoC AHCI SATA Host Controller driver. This print was due to the fact that the controller 3 don't have a mux resource. This didn't result in any errors but the print seems like meaningless.

2014-09-06ahci_xgene: Fix the link down in first attempt for the APM X-Gene SoC AHCI ↵Suman Tripathi1-14/+34
SATA host controller driver. Due to HW errata the APM X-Gene AHCI SATA host controller reports link down even if the device presence is detected. This issue is due to speed negotiation failure. This patch implements the algorithm to retry the COMRESET if PxSTAT register reports device presence detected but PHY communication not established. The maximum retry attempts are 3. This patch also fixes the code to match the algorithm for the printing a warning message if the disparity error still exists after link up.

After enabled the PM feature that supporting async noirq(76569faa62 (PM / sleep: Asynchronous threads for resume_noirq)), Jay hit the system resuming issue, that one of the JMicron controller can not be powered up. His device tree is like below: +-1c.4-[02]--+-00.0 JMicron Technology Corp. JMB363 SATA/IDE Controller | \-00.1 JMicron Technology Corp. JMB363 SATA/IDE Controller After investigation, we found the the Micron chip 363 included one SATA controller(0000:02:00.0) and one PATA controller(0000:02:00.1), these two controllers do not have parent-children relationship, but the PATA controller only can be powered on after the SATA controller has finished the powering on. If we enabled the async noirq(), then the below error is hit during noirq phase: pata_jmicron 0000:02:00.1: Refused to change power state, currently in D3 Here for JMicron chip 363/361, we need forcedly to disable the async method.
