2008-10-24libata: fix bug with non-ncq devicesJens Axboe1-1/+5
The recent commit 2fca5ccf97d2c28bcfce44f5b07d85e74e3cd18e ("libata: switch to using block layer tagging support") to enable support for block layer tagging in libata was broken for non-NCQ devices The block layer initializes the tag field to -1 to detect invalid uses of a tag, and if the libata devices does NOT support NCQ, we just used that field to index the internal command list. So we need to check for -1 first and only use the tag field if it's valid.

2008-10-23libata: switch to using block layer tagging supportJens Axboe3-64/+31
libata currently has a pretty dumb ATA_MAX_QUEUE loop for finding a free tag to use. Instead of fixing that up, convert libata to using block layer tagging - gets rid of code in libata, and is also much faster.

2008-10-22libata: set device class to NONE if phys_offlineTejun Heo1-8/+8
Reset methods don't have access to phys link status for slave links and may incorrectly indicate device presence causing unnecessary probe failures for unoccupied links. This patch clears device class to NONE during post-reset processing if phys link is offline. As on/offlineness semantics is strictly defined and used in multiple places by the core layer, this won't change behavior for drivers which don't use slave links.

2008-10-22libata-eh: fix slave link EH action mask handlingTejun Heo1-1/+4
Slave link action mask is transferred to master link and all the EH actions are taken by the master link. ata_eh_about_to_do() and ata_eh_done() are called with ATA_EH_ALL_ACTIONS to clear the slave link actions during transfer. This always sets ATA_PFLAG_RECOVERED flag causing spurious "EH complete" messages. Don't set ATA_PFLAG_RECOVERED for slave link actions.

2008-10-22libata: transfer EHI control flags to slave ehc.iTejun Heo1-0/+5
ATA_EHI_NO_AUTOPSY and ATA_EHI_QUIET are used to control the behavior of EH. As only the master link is visible outside EH, these flags are set only for the master link although they should also apply to the slave link, which causes spurious EH messages during probe and suspend/resume.

2008-10-10powerpc: Fix no interrupt handling in pata_of_platformAnton Vorontsov1-1/+1
When no interrupt is specified the pata_of_platform fills the irq_res resource with -1, which is wrong to do for two reasons: 1. By definition, 'no irq' should be IRQ 0, not some negative integer; 2. pata_platform checks for irq_res.start > 0, but since irq_res.start is unsigned type, the check will be true for `-1'.

Right now SCSI and others do their own command timeout handling. Move those bits to the block layer. Instead of having a timer per command, we try to be a bit more clever and simply have one per-queue. This avoids the overhead of having to tear down and setup a timer for each command, so it will result in a lot less timer fiddling.

2008-09-29libata-eh: clear UNIT ATTENTION after resetTejun Heo1-0/+94
Resets make ATAPI devices raise UNIT ATTENTION which fails the next command. As resets can happen asynchronously for unrelated reasons, this sometimes disrupts innocent users. For example, reading DVD fails after the system wakes up from suspend or the other device sharing the channel went through bus error. Clearing UA has some problems as it might clear UA which the userland needs to know about. However, UA after resets can only be about the reset itself and benefits of clearing it overweights cons. Missing UA can only delay failure to one of the following commands anyway. For example, timeout while burning is in progress will trigger reset and reset the device state and probably corrupt the burning run. Although the userland application won't get the UA, its pending writes will fail. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2008-09-29libata: Implement disk shock protection supportElias Oltmanns4-1/+235
On user request (through sysfs), the IDLE IMMEDIATE command with UNLOAD FEATURE as specified in ATA-7 is issued to the device and processing of the request queue is stopped thereafter until the specified timeout expires or user space asks to resume normal operation. This is supposed to prevent the heads of a hard drive from accidentally crashing onto the platter when a heavy shock is anticipated (like a falling laptop expected to hit the floor). In fact, the whole port stops processing commands until the timeout has expired in order to avoid any resets due to failed commands on another device.

2008-09-29libata: implement slave_linkTejun Heo3-49/+298
Explanation taken from the comment of ata_slave_link_init(). In libata, a port contains links and a link contains devices. There is single host link but if a PMP is attached to it, there can be multiple fan-out links. On SATA, there's usually a single device connected to a link but PATA and SATA controllers emulating TF based interface can have two - master and slave. However, there are a few controllers which don't fit into this abstraction too well - SATA controllers which emulate TF interface with both master and slave devices but also have separate SCR register sets for each device. These controllers need separate links for physical link handling (e.g. onlineness, link speed) but should be treated like a traditional M/S controller for everything else (e.g. command issue, softreset). slave_link is libata's way of handling this class of controllers without impacting core layer too much. For anything other than physical link handling, the default host link is used for both master and slave. For physical link handling, separate @ap->slave_link is used. All dirty details are implemented inside libata core layer. From LLD's POV, the only difference is that prereset, hardreset and postreset are called once more for the slave link, so the reset sequence looks like the following. prereset(M) -> prereset(S) -> hardreset(M) -> hardreset(S) -> softreset(M) -> postreset(M) -> postreset(S) Note that softreset is called only for the master. Softreset resets both M/S by definition, so SRST on master should handle both (the standard method will work just fine). As slave_link excludes PMP support and only code paths which deal with the attributes of physical link are affected, all the changes are localized to libata.h, libata-core.c and libata-eh.c. * ata_is_host_link() updated so that slave_link is considered as host link too. * iterator extended to iterate over the slave_link when using the underbarred version. * force param handling updated such that devno 16 is mapped to the slave link/device. * ata_link_on/offline() updated to return the combined result from master and slave link. ata_phys_link_on/offline() are the direct versions. * EH autopsy and report are performed separately for master slave links. Reset is udpated to implement the above described reset sequence. Except for reset update, most changes are minor, many of them just modifying dev->link to ata_dev_phys_link(dev) or using phys online test instead. After this update, LLDs can take full advantage of per-dev SCR registers by simply turning on slave link. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

Previously, broken hardreset could go unnoticed as it wasn't used during probing but when something goes wrong or after hotplug the problem will surface and bite hard.

2008-09-08ahci, pata_marvell: play nicely togetherAlan Cox3-15/+59
I've been chasing Jeff about this for months. Jeff added the Marvell device identifiers to the ahci driver without making the AHCI driver handle the PATA port. This means a lot of users can't use current kernels and in most distro cases can't even install. This has been going on since March 2008 for the 6121 Marvell, and late 2007 for the 6145!!! This was all pointed out at the time and repeatedly ignored. Bugs assigned to Jeff about this are ignored also. To quote Jeff in email > "Just switch the order of 'ahci' and 'pata_marvell' in > /etc/modprobe.conf, then use Fedora's tools regenerate the initrd. > See? It's not rocket science, and the current configuration can be > easily made to work for Fedora users." (Which isn't trivial, isn't end user, shouldn't be needed, and as it usually breaks at install time is in fact impossible) To quote Jeff in August 2007 > " mv-ahci-pata > Marvell 6121/6141 PATA support. Needs fixing in the 'PATA controller > command' area before it is usable, and can go upstream." Only he add the ids anyway later and caused regressions, adding a further id in March causing more regresions. The actual fix for the moment is very simple. If the user has included the pata_marvell driver let it drive the ports. If they've only selected for SATA support give them the AHCI driver which will run the port a fraction faster. Allow the user to control this decision via ahci.marvell_enable as a module parameter so that distributions can ship 'it works' defaults and smarter users (or config tools) can then flip it over it desired.

2008-08-31sparc: remove CONFIG_SUN4Adrian Bunk1-1/+0
While doing some easy cleanups on the sparc code I noticed that the CONFIG_SUN4 code seems to be worse than the rest - there were some "I don't know how it should work, but the current code definitely cannot work." places. And while I have seen people running Linux on machines like a SPARCstation 5 a few years ago I don't recall having seen sun4 machines, even less ones running Linux.

2008-08-23pcmcia: pcmcia_config_loop() improvement by passing vccDominik Brodowski1-8/+4
By passing the current Vcc setting to the pcmcia_config_loop callback function, we can remove pcmcia_get_configuration_info() calls from many drivers. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2008-08-23pcmcia: pcmcia_config_loop() default CIS entry handlingDominik Brodowski1-18/+15
Many drivers use the default CIS entry within their pcmcia_config_loop() callback function. Therefore, factor the default CIS entry handling out. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
