linux.git/drivers/ata, branch v6.6-rc2 Linux kernel source tree ata: libata-core: fetch sense data for successful commands iff CDL enabled 2023-09-16T12:12:19+00:00 Niklas Cassel niklas.cassel@wdc.com 2023-09-13T15:04:43+00:00 5e35a9ac3fe3a0d571b899a16ca84253e53dc70c Currently, we fetch sense data for a _successful_ command if either: 1) Command was NCQ and ATA_DFLAG_CDL_ENABLED flag set (flag ATA_DFLAG_CDL_ENABLED will only be set if the Successful NCQ command sense data supported bit is set); or 2) Command was non-NCQ and regular sense data reporting is enabled. This means that case 2) will trigger for a non-NCQ command which has ATA_SENSE bit set, regardless if CDL is enabled or not. This decision was by design. If the device reports that it has sense data available, it makes sense to fetch that sense data, since the sk/asc/ascq could be important information regardless if CDL is enabled or not. However, the fetching of sense data for a successful command is done via ATA EH. Considering how intricate the ATA EH is, we really do not want to invoke ATA EH unless absolutely needed. Before commit 18bd7718b5c4 ("scsi: ata: libata: Handle completion of CDL commands using policy 0xD") we never fetched sense data for successful commands. In order to not invoke the ATA EH unless absolutely necessary, even if the device claims support for sense data reporting, only fetch sense data for successful (NCQ and non-NCQ commands) commands that are using CDL. [Damien] Modified the check to test the qc flag ATA_QCFLAG_HAS_CDL instead of the device support for CDL, which is implied for commands using CDL.

Currently, we fetch sense data for a _successful_ command if either:
1) Command was NCQ and ATA_DFLAG_CDL_ENABLED flag set (flag
   ATA_DFLAG_CDL_ENABLED will only be set if the Successful NCQ command
   sense data supported bit is set); or
2) Command was non-NCQ and regular sense data reporting is enabled.

This means that case 2) will trigger for a non-NCQ command which has
ATA_SENSE bit set, regardless if CDL is enabled or not.

This decision was by design. If the device reports that it has sense data
available, it makes sense to fetch that sense data, since the sk/asc/ascq
could be important information regardless if CDL is enabled or not.

However, the fetching of sense data for a successful command is done via
ATA EH. Considering how intricate the ATA EH is, we really do not want to
invoke ATA EH unless absolutely needed.

Before commit 18bd7718b5c4 ("scsi: ata: libata: Handle completion of CDL
commands using policy 0xD") we never fetched sense data for successful
commands.

In order to not invoke the ATA EH unless absolutely necessary, even if the
device claims support for sense data reporting, only fetch sense data for
successful (NCQ and non-NCQ commands) commands that are using CDL.

[Damien] Modified the check to test the qc flag ATA_QCFLAG_HAS_CDL
instead of the device support for CDL, which is implied for commands
using CDL.

ata: libata-eh: do not thaw the port twice in ata_eh_reset() 2023-09-16T12:11:28+00:00 Niklas Cassel niklas.cassel@wdc.com 2023-09-13T22:19:17+00:00 7a3bc2b3989e05bbaa904a63279049a401491c84 commit 1e641060c4b5 ("libata: clear eh_info on reset completion") added a workaround that broke the retry mechanism in ATA EH.

Since commit 1e641060c4b5 ("libata: clear eh_info on reset completion") has now been reverted, the ATA EH retry mechanism is functional again, so there is once again no need to thaw the port more than once in ata_eh_reset().

a workaround that broke the retry mechanism in ATA EH.

Tejun himself suggested to remove this workaround when it was identified

kept to avoid "spurious hotplug events during reset", and instead another
workaround was added on top of the existing workaround in commit
8c56cacc724c ("libata: fix unexpectedly frozen port after ata_eh_reset()").

That is, if a port has one or more interrupt status bit set, and the enables for those status bits are set, then this bit shall be set." Additionally, AHCI state P:ComInit clearly shows that the state machine will only jump to P:ComInitSetIS (which sets IS.IPS(x) to '1'), if PxIE.PCE is set to '1'. In our case, PxIE is set to 0, so IS.IPS(x) won't get set. So IS.IPS(x) only gets set if PxIS and PxIE is set. AHCI 1.3.1 section 10.7.1.1 First Tier (IS Register) also states: "The bits in this register are read/write clear. It is set by the level of the virtual interrupt line being a set, and cleared by a write of '1' from the software." So if IS.IPS(x) is set, you need to explicitly clear it by writing a 1 to IS.IPS(x) for that port. Since PxIE is cleared, the only way to get an interrupt while the port is frozen, is if IS.IPS(x) is set, and the only way IS.IPS(x) can be set when the port is frozen, is if it was set before the port was frozen. However, since commit 737dd811a3db ("ata: libahci: clear pending interrupt status"), we clear both PxIS and IS.IPS(x) after freezing the port, but before the COMRESET, so the problem that commit 1e641060c4b5 ("libata: clear eh_info on reset completion") fixed can no longer happen. Thus, revert commit 1e641060c4b5 ("libata: clear eh_info on reset completion"), so that the retry logic in ata_scsi_port_error_handler() works once again.

ata_scsi_port_error_handler() starts off by clearing ATA_PFLAG_EH_PENDING,
before calling ap->ops->error_handler() (without holding the ap->lock).

If an error IRQ is received while ap->ops->error_handler() is running,
the irq handler will set ATA_PFLAG_EH_PENDING.

Once ap->ops->error_handler() returns, ata_scsi_port_error_handler()
checks if ATA_PFLAG_EH_PENDING is set, and if it is, another iteration
of ATA EH is performed.

The problem is that ATA_PFLAG_EH_PENDING is not only cleared by
ata_scsi_port_error_handler(), it is also cleared by ata_eh_reset().

ata_eh_reset() is called by ap->ops->error_handler(). This additional
clearing done by ata_eh_reset() breaks the whole retry logic in
ata_scsi_port_error_handler(). Thus, if an error IRQ is received while
ap->ops->error_handler() is running, the port will currently remain
frozen and will never get re-enabled.

The additional clearing in ata_eh_reset() was introduced in commit
1e641060c4b5 ("libata: clear eh_info on reset completion").

Looking at the original error report:
https://marc.info/?l=linux-ide&m=124765325828495&w=2

We can see the following happening:
[    1.074659] ata3: XXX port freeze
[    1.074700] ata3: XXX hardresetting link, stopping engine
[    1.074746] ata3: XXX flipping SControl

We are not supposed to be able to receive an error IRQ while the port is
frozen (PxIE is set to 0, i.e. all IRQs for the port are disabled).

AHCI 1.3.1 section 10.7.1.1 First Tier (IS Register) states:
"Each bit location can be thought of as reporting a '1' if the virtual
"interrupt line" for that port is indicating it wishes to generate an
interrupt. That is, if a port has one or more interrupt status bit set,
and the enables for those status bits are set, then this bit shall be set."

Additionally, AHCI state P:ComInit clearly shows that the state machine
will only jump to P:ComInitSetIS (which sets IS.IPS(x) to '1'), if PxIE.PCE
is set to '1'. In our case, PxIE is set to 0, so IS.IPS(x) won't get set.

So IS.IPS(x) only gets set if PxIS and PxIE is set.

AHCI 1.3.1 section 10.7.1.1 First Tier (IS Register) also states:
"The bits in this register are read/write clear. It is set by the level of
the virtual interrupt line being a set, and cleared by a write of '1' from
the software."

So if IS.IPS(x) is set, you need to explicitly clear it by writing a 1 to
IS.IPS(x) for that port.

Since PxIE is cleared, the only way to get an interrupt while the port is
frozen, is if IS.IPS(x) is set, and the only way IS.IPS(x) can be set when
the port is frozen, is if it was set before the port was frozen.

However, since commit 737dd811a3db ("ata: libahci: clear pending interrupt
status"), we clear both PxIS and IS.IPS(x) after freezing the port, but
before the COMRESET, so the problem that commit 1e641060c4b5 ("libata:
clear eh_info on reset completion") fixed can no longer happen.

Thus, revert commit 1e641060c4b5 ("libata: clear eh_info on reset
completion"), so that the retry logic in ata_scsi_port_error_handler()
works once again. (The retry logic is still needed, since we can still
get an error IRQ _after_ the port has been thawed, but before
ata_scsi_port_error_handler() takes the ap->lock in order to check
if ATA_PFLAG_EH_PENDING is set.)

If the adapter receives another SDB FIS with an error (PxIS.TFES) from the device before the start of the EH recovery process, the interrupt signaling the new SDB cannot be serviced as PxIE was cleared already.

Micron 1100 drives lock up when encountering queued TRIM command. It is
a quite old hardware series, for past years we have been running our
machines with these drives using libata.force=noncqtrim.

[Damien] Move the "Crucial_CT*M500*" entry to keep Micron and Crucial
entries together.
