| | * [libata] Improve timeout handlingAlan Cox2009-03-2510-5/+85
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On a timeout call a device specific handler early in the recovery so that we can complete and process successful commands which timed out due to IRQ loss or the like rather more elegantly. [Revised to exclude the timeout handling on a few devices that inherit from SFF but are not SFF enough to use the default timeout handler] Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

| | * [libata] More robust parsing for IDENTIFY DEVICE multi_count fieldMark Lord2009-03-251-2/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make libata more robust when parsing the multi_count field from a drive's identify data. This prevents us from attempting to use dubious multi_count values ad infinitum. Reset dev->multi_count to zero and reprobe it each time through this routine, as it can change on device reset. Also ensure that the reported "maximum" value is valid and is a power of two, and that the reported "count" value is valid and also a power of two. And that the "count" value is not greater than the "maximum" value. Signed-off-by: Mark Lord <mlord@pobox.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
| | * sata_mv: fix LED blinking for SoC+NCQMark Lord2009-03-251-0/+68
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For Marvell SoC chips, the HDD LED does not blink when there is disk I/O if NCQ is enabled. Add a quirk that enables blink mode for the LED while NCQ is enabled on any port of a SoC host controller. Normal LED function is restored when NCQ is not enabled on any port. The code to enable the blink mode is based on earlier code and suggestions from Frans Pop, Saeed Bishara, and possibly others.

| | * sata_mv: optimize IRQ coalescing for 8-port chipsMark Lord2009-03-251-14/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Enable use of the "all ports" IRQ coalescing optimization for GEN_II / GEN_IIE chips that have dual host-controllers (8-ports). Currently only the 6081 chip qualifies, but other chips may come along someday. Rather than each half of the chip having to satisfy a local set of coalescing thresholds, use of this feature groups all ports together under a single set of thresholds.

| | * sata_mv: implement IRQ coalescing (v2)Mark Lord2009-03-251-8/+135
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add IRQ coalescing to sata_mv (off by default). This feature can reduce total interrupt overhead for RAID setups in some situations, by deferring the interrupt signal until one or both of: a) a specified io_count (completed SATA commands) is achieved, or b) a specified time interval elapses after an IO completion. For now, module parameters are used to set the irq_coalescing_io_count and irq_coalescing_usecs (timeout) globally. These may eventually be supplemented with sysfs attributes, so that thresholds can be set on-the-fly and on a per-chip (or even per-host_controller) basis.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is necessary for use with the upcoming "mv_qc_issue_fis()" patch, but is being added separately here for easier code review. When using command issue via the "mv_qc_issue_fis()" mechanism, the initial ATA_BUSY bit does not show in the ATA status (shadow) register. This can confuse libata! So here we add a hook to fake ATA_BUSY for that situation, until the first time a BUSY, DRQ, or ERR bit is seen.

| | * [libata] sata_mv: Enable use of (basic) DMA for ATAPI on GEN_IIE chipsMark Lord2009-03-251-24/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This also gets rid of any need for mv_mode_filter(). Using basic DMA on GEN_IIE requires setting an undocumented bit in an undocumented register. For safety, we clear that bit again when switching back to EDMA mode. To avoid a performance penalty when switching modes, we cache the register in port_priv, as already done for other regs.

| | * ahci: drop intx manipulation on msi enableTejun Heo2009-03-251-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's no need to turn off intx explicitly on msi enable. This is automatically handled by pci. Drop it. This might be needed on machines if the BIOS turns intx off during boot. However, there's no evidence of such behavior for ahci and the only such case seems to be ICH5 PATA according to ata_piix. Also, given the way ahci operates, it's highly unlikely BIOS ever disables IRQ for the controller. However, as this change has slight possibility of introducing failure, please schedule it for #upstream. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I'm not quite sure what freezing and thawing is used for. Tests showed that the port is being frozen at initialisation state and thawed right afterwards, then the functions were not called anymore. Dropping the complete custom code for handling the frozen state seems to work at least for a standard use case including mounting a partition, copying some files in it (in parallel) and finally removing them and unmounting the partition.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The biggest difference between rb532_pata_data_xfer() and ata_sff_data_xfer32() is the call to ata_sff_pause() at the end of rb532_pata_data_xfer() which I suppose to be unnecessary since it works without. I've also tested using ata_sff_data_xfer() as replacement, but since we know that the driver supports 32bit IO, using the optimised version should be safe.

| | * | USB: more u32 conversion after transfer_buffer_length and actual_lengthRoel Kluin2009-03-255-25/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | transfer_buffer_length and actual_length have become unsigned, therefore some additional conversion of local variables, function arguments and print specifications is desired. A test for a negative urb->transfer_buffer_length became obsolete; instead we ensure that it does not exceed INT_MAX. Also, urb->actual_length is always less than urb->transfer_buffer_length. rh_string() does no longer return -EPIPE in the case of an unsupported ID. Instead its only caller, rh_call_control() does the check.

| | * | USB: Fix cp2101 USB serial device driver termios functions for console useVomLehn2009-03-251-10/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is really a follow up to the modifications Alan Cox made for commit 95da310e66ee8090119596c70ca8432e57f9a97f to pass a tty_struct to various interface functions, which broke the serial configuration (termios) functions when the device is being used as a console. These changes restore the configuration to proper functioning both as a tty and as a console. As Alan notes in that commit, these changes will need to be tweaked when we have a proper console abstraction.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ipaq driver currently enforces one port on all devices. This is correct for 2 and 3 endpoint devices, but with 4 endpoint devices meaningful communication occurs on the second pair. This patch allows 2 ports for 4 endpoint devices.
