This patch refines ahci_kick_engine() after discussion with Tejun about
FBS(FIS-based switching) support preparation:
a. Kill @force_restart and always kick the engine. The only case where
@force_restart is zero is when it's called from ahci_p5wdh_hardreset()
Actually at that point, BSY is pretty much guaranteed to be set.
b. If PMP is attached, ignore busy and always do CLO. (AHCI-1.3 9.2)

ata_tf_read_block() has off-by-one error when converting CHS address
to LBA. The bug isn't very visible because ata_tf_read_block() is
used only when generating sense data for a failed RW command and CHS
addressing isn't used too often these days.

It turns out ASUS M2A-VM isn't the only one with the 32bit DMA
problem. Make ahci_asus_m2a_vm_32bit_only() more generic using the
new dmi_get_date() and rename it to ahci_sb600_32bit_only(). Cut off
date is now pointed to by dmi_system_id->driver_data in "yyyymmdd"
format and it's now also allowed to be omitted.

There are cases where full date information is required instead of
just the year. Add month and day parsing to dmi_get_year() and rename
it to dmi_get_date().
As the original function only required '/' followed by any number of
parseable characters at the end of the string, keep that behavior to
avoid upsetting existing users.
The new function takes dates of format [mm[/dd]]/yy[yy]. Year, month
and date are checked to be in the ranges of [1-9999], [1-12] and
[1-31] respectively and any invalid or out-of-range component is
returned as zero.
The dummy implementation is updated accordingly but the return value
is updated to indicate field not found which is consistent with how
other dummy functions behave.

ata_scsi_pass_thru() was checking for input sanity and disallowed
commands while initializaing qc from scmd. TPM filtering was added
right after protocol check at which point tf wasn't initialized
properly. This means that TPM filtering has never really worked.
This patch fixes the bug by reorganizing ata_scsi_pass_thru() such
that qc is fully initialized before checking for invalid conditions
which is way less error prone.
Discovered while Thilo-Alexander Ginkel was trying debug patches for
bko#13416.

During introduction of slave_link, sata_sis slipped through the crack
and left with ad-hoc merged SCR access. As SCR status was shared for
both the master and slave devices, when only one of the device is
online, libata EH would think both are online but would only get valid
device signature for the actually present one, which in turn trigger
the probing safety net mechanism and make EH retry causing large delay
during boot. This patch converts sata_sis to slave_link mechanism.
This bug was reported by TAXI in bko#14075.

The sil24 hardware has a built-in list of commands and associated protocols
that gets used by default to decide how to handle a given command. However,
if the command is not known to the controller then it presumably assumes it to
be a non-data command which then causes protocol mismatch errors if the device
ends up requesting data transfer. The new DATA SET MANAGEMENT - Trim command
causes this issue since it's a DMA data-out command.
Since we should always know best what protocol the command should be using,
let's just set the override flag to inform the controller what protocol to use
for all non-ATAPI commands with data transfer.

AHCI exports various capability bits that may be of interest to userspace
such as whether the BIOS claims a port is hotpluggable or eSATA. Providing
these via sysfs along with the version of the AHCI spec implemented by
the host allows userspace to make policy decisions for things like ALPM.

This patch improve libata's output for error/notification messages
to allow easier comprehension and debugging:
When ATAPI commands issued through the SCSI layer fail, use SCSI
functions to print the CDB in human-readable form instead of just
dumping out the CDB in hex.
Print out the name of the failed command (as defined by the ATA
specification) in error handling output along with the raw register
contents.
When reporting status of ACPI taskfile commands executed on resume,
also output the names of the commands being executed (or not) in
readable form.
Since the extra data for printing command names increases kernel
size slightly, a config option has been added to allow disabling
command name output (as well as some of the error register parsing)
for those highly sensitive to kernel text size.

Resets are done with port frozen but some controllers still issue
interrupts during reset and they may end up recording error conditions
in ehi leading to unnecessary EH retrials.
This patch makes ata_eh_reset() clear ehi on reset completion. As
reset is the most severe recovery action, there's nothing to lose by
clearing ehi on its completion.

Commit log for commit 517d3cc15b36392e518abab6bacbb72089658313
("[libata] ata_piix: Enable parallel scan") says:
This patch turns on parallel scanning for the ata_piix driver.
This driver is used on most netbooks (no AHCI for cheap storage it seems).
The scan is the dominating time factor in the kernel boot for these
devices; with this flag it gets cut in half for the device I used
for testing (eeepc).
Alan took a look at the driver source and concluded that it ought to be safe
to do for this driver. Alan has also checked with the hardware team.
and it is all true but once we put all things together additional
constraints for PATA controllers show up (some hardware registers
have per-host not per-port atomicity) and we risk misprogramming
the controller.
I used the following test to check whether the issue is real:
@@ -736,8 +736,20 @@ static void piix_set_piomode(struct ata_
(timings[pio][1] << 8);
}
pci_write_config_word(dev, master_port, master_data);
- if (is_slave)
+ if (is_slave) {
+ if (ap->port_no == 0) {
+ u8 tmp = slave_data;
+
+ while (slave_data == tmp) {
+ pci_read_config_byte(dev, slave_port, &tmp);
+ msleep(50);
+ }
+
+ dev_printk(KERN_ERR, &dev->dev, "PATA parallel scan "
+ "race detected\n");
+ }
pci_write_config_byte(dev, slave_port, slave_data);
+ }
/* Ensure the UDMA bit is off - it will be turned back on if
UDMA is selected */
and it indeed triggered the error message.
Lets fix all such races by adding an extra locking to ->set_piomode
and ->set_dmamode methods for PATA controllers.
[ Alan: would be better to take the host lock in libata-core for these
cases so that we fix all the adapters in one swoop. "Looks fine as a
temproary quickfix tho" ]

Some gigabytes have on-board SIMG5723s connected to JMB ahcis. These
are used to implement hardware raid. Unfortunately some firmware
revisions on these 5723s don't bring the link down when all the
downstream ports are unoccupied while not responding to reset protocol
which makes libata think that there's device attached to the port but
is not responding and retry. This results in painfully wrong boot
detection time for these ports when they're empty.
This patch quirks those boards such that ahci gives up after the
initial timeout. Combined with parallel probing, this gives quick
enough probing and also is safe because SIMG5723 will respond to the
first try if any of the downstream ports is occupied.

On certain configurations, HPA isn't or can't be unlocked during
probing but it somehow ends up unlocked afterwards. In the following
thread, the problem can be reliably reproduced after resuming from
STR. The BIOS turns on HPA during boot but forgets to do it during
resume.
http://thread.gmane.org/gmane.linux.kernel/858310
This patch updates libata revalidation such that it considers native
n_sectors. If the device size has increased to match native
n_sectors, it's assumed that HPA has been unlocked involuntarily and
the device is recognized as the same one. This should be fairly safe
while nicely working around the problem.

No need to include any specific headers for at91sam9260 SoC.
* No harsh BUG_ON for get_clk in set_smc_timing function
