2015-12-07ata/sata_fsl.c: add ATA_FLAG_NO_LOG_PAGE to blacklist the controller for log ↵Andreas Werner1-1/+2
page reads Every attempt to issue a read log page command lockup the controller. The command is currently sent if the sata device includes the devlsp feature to read out the timing data. This attempt to read the data, locks up the controller and the device is not recognzied correctly (failed to set xfermode) and cannot be accessed. This was found on Freescale P1013/P1022 and T4240 CPUs using a ATP IG mSATA 4GB with the devslp feature. fsl-sata ff718000.sata: Sata FSL Platform/CSB Driver init [ 1.254195] scsi0 : sata_fsl [ 1.256004] ata1: SATA max UDMA/133 irq 74 [ 1.370666] fsl-gianfar ethernet.3: enabled errata workarounds, flags: 0x4 [ 1.470671] fsl-gianfar ethernet.4: enabled errata workarounds, flags: 0x4 [ 1.775584] ata1: Signature Update detected @ 504 msecs [ 1.947594] ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300) [ 1.948366] ata1.00: ATA-8: ATP IG mSATA, 20150311, max UDMA/133 [ 1.948371] ata1.00: 7732368 sectors, multi 0: LBA [ 1.948843] ata1.00: failed to get Identify Device Data, Emask 0x1 [ 1.948857] ata1.00: failed to set xfermode (err_mask=0x40) [ 7.467557] ata1: Signature Update detected @ 504 msecs [ 7.639560] ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300) [ 7.651320] ata1.00: failed to get Identify Device Data, Emask 0x1 [ 7.651360] ata1.00: failed to set xfermode (err_mask=0x40) [ 7.655628] ata1: limiting SATA link speed to 1.5 Gbps [ 7.659458] ata1.00: limiting speed to UDMA/133:PIO3 [ 13.163554] ata1: Signature Update detected @ 504 msecs [ 13.335558] ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300) [ 13.347298] ata1.00: failed to get Identify Device Data, Emask 0x1 [ 13.347334] ata1.00: failed to set xfermode (err_mask=0x40) [ 13.351601] ata1.00: disabled [ 13.353278] ata1: exception Emask 0x50 SAct 0x0 SErr 0x800 action 0x6 frozen t4 [ 13.359281] ata1: SError: { HostInt } [ 13.361644] ata1: hard resetting link Signed-off-by: Andreas Werner <andreas.werner@men.de> Signed-off-by: Tejun Heo <tj@kernel.org>

2015-11-30AHCI: Fix softreset failed issue of Port MultiplierXiangliang Yu1-0/+9
Current code doesn't update port value of Port Multiplier(PM) when sending FIS of softreset to device, command will fail if FBS is enabled. There are two ways to fix the issue: the first is to disable FBS before sending softreset command to PM device and the second is to update port value of PM when sending command. For the first way, i can't find any related rule in AHCI Spec. The second way can avoid disabling FBS and has better performance.

This patch changes the !blk-mq path to the same defaults as the blk-mq I/O path by always enabling block tagging, and always using host wide tags. We've had blk-mq available for a few releases so bugs with this mode should have been ironed out, and this ensures we get better coverage of over tagging setup over different configs.

2015-10-01ata: ahci: find eSATA ports and flag them as removableManuel Lauss3-2/+14
If the AHCI ports' HPCP or ESP bits are set, the port should be considered external (e.g. eSATA) and is marked as removable. Userspace tools like udisks then treat it like an usb drive. With this patch applied, when I plug a drive into the esata port, KDE pops up a window asking what to do with the drives(s), just like it does for any random USB stick. Removability is indicated to the upper layers by way of the SCSI RMB bit, as I haven't found another way to signal userspace to treat a sata disk like any usb stick.

Currently Freescale QorIQ series SATA is supported by ahci_platform driver. Some SoC specific settings have been put in uboot. So whether SATA works or not heavily depends on uboot.

2015-09-03MIPS: Remove all the uses of custom gpio.hAlban Bedel1-2/+1
Currently CONFIG_ARCH_HAVE_CUSTOM_GPIO_H is defined for all MIPS machines, and each machine type provides its own gpio.h. However only a handful really implement the GPIO API, most just forward everythings to gpiolib. The Alchemy machine is notable as it provides a system to allow implementing the GPIO API at the board level. But it is not used by any board currently supported, so it can also be removed. For most machine types we can just remove the custom gpio.h, as well as the custom wrappers if some exists. Some of the code found in the wrappers must be moved to the respective GPIO driver. A few more fixes are need in some drivers as they rely on linux/gpio.h to provides some machine specific definitions, or used asm/gpio.h instead of linux/gpio.h for the gpio API.

2015-08-24PCI: Disable async suspend/resume for JMicron multi-function SATA/AHCIZhang Rui2-24/+1
On multi-function JMicron SATA/PATA/AHCI devices, the PATA controller at function 1 doesn't work if it is powered on before the SATA controller at function 0. The result is that PATA doesn't work after resume, and we print messages like this: pata_jmicron 0000:02:00.1: Refused to change power state, currently in D3 irq 17: nobody cared (try booting with the "irqpoll" option) Async resume was introduced in v3.15 by 76569faa62c4 ("PM / sleep: Asynchronous threads for resume_noirq"). Prior to that, we powered on the functions in order, so this problem shouldn't happen. e6b7e41cdd8c ("ata: Disabling the async PM for JMicron chip 363/361") solved the problem for JMicron 361 and 363 devices. With async suspend disabled, we always power on function 0 before function 1. Barto then reported the same problem with a JMicron 368 (see comment #57 in the bugzilla). Rather than extending the blacklist piecemeal, disable async suspend for all JMicron multi-function SATA/PATA/AHCI devices. This quirk could stay in the ahci and pata_jmicron drivers, but it's likely the problem will occur even if pata_jmicron isn't loaded until after the suspend/resume. Making it a PCI quirk ensures that we'll preserve the power-on order even if the drivers aren't loaded.

2015-07-15libata: increase the timeout when setting transfer modeMikulas Patocka1-1/+2
I have a ST4000DM000 disk. If Linux is booted while the disk is spun down, the command that sets transfer mode causes the disk to spin up. The spin-up takes longer than the default 5s timeout, so the command fails and timeout is reported. Fix this by increasing the timeout to 15s, which is enough for the disk to spin up.

limit Since no longer limiting max_sectors to BLK_DEF_MAX_SECTORS (commit 34b48db66e08), data corruption may occur on ST380013AS drive configured on 82801JI (ICH10 Family) SATA controller. This patch will allow the driver to limit max_sectors as before # cat /sys/block/sdb/queue/max_sectors_kb 512 I was able to double the max_sectors_kb value up to 16384 on linux-4.2.0-rc2 before seeing corruption, but seems safer to use previous limit.
