[ATA] Increase lba48 max-sectors from 200 to 256. Also, moved ATA_MAX_SECTORS and ATA_MAX_SECTORS_LBA48 from linux/libata.h to linux/ata.h, now that they truly reflect the standard (well... mostly; note TODO comment). This changes the performance profile (and potential bug profile) for a bunch of drivers, so be wary.

libata: add ATA_HORKAGE_MAX_SEC_1024 to revert back to previous max_sectors 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. Without this patch max_sectors_kb will be 32767. tj: Minor comment update.

ata: make lba_{28,48}_ok() use ATA_MAX_SECTORS{,_LBA48} Since we set ATA_MAX_SECTORS_LBA48 to 65535 to avoid the corner case in some drives that commands with "count" set to 0000h (which reprsents 65536) does not work as expected, lba_48_ok(), which is used for number-of-blocks checking when libata pack commands, should use the same limit as well.

libata: increase 128 KB / cmd limit for ATAPI tape drives Commands sent to ATAPI tape drives via the SCSI generic (sg) driver are limited in the amount of data that they can transfer by the max_sectors value. The max_sectors value is currently calculated according to the command set for disk drives, which doesn't apply to tape drives. The default max_sectors value of 256 limits ATAPI tape drive commands to 128 KB. This patch against 2.6.24-rc1 increases the max_sectors value for tape drives to 65535, which permits tape drive commands to transfer just under 32 MB. Tested with a SuperMicro PDSME motherboard, AHCI, and a Sony SDX-570V SATA tape drive. Note that some of the chipset drivers also set their own max_sectors value, which may override the value set in libata-core. I don't have any of these chipsets to test, so I didn't go messing with them. Also, ATAPI devices other than tape drives may benefit from similar changes, but I have only tape drives and disk drives to test.

libata-scsi: avoid repeated calculation of number of TRIM ranges Currently libata statically allows only 1-block (512-byte) payload for each TRIM command. Each payload can carry 64 TRIM ranges since each range requires 8 bytes. It is silly to keep doing the calculation (512 / 8) in different places. Hence, define the new ATA_MAX_TRIM_RNUM for the result. Signed-off-by: Tom Yan <tom.ty89@gmail.com> Signed-off-by: Tejun Heo <tj@kernel.org>

libata: check for trusted computing in IDENTIFY DEVICE data ATA-8 and later mirrors the TRUSTED COMPUTING SUPPORTED bit in word 48 of the IDENTIFY DEVICE data. Check this before issuing a READ LOG PAGE command to avoid issues with buggy devices. The only downside is that we can't support Security Send / Receive for a device with an older revision due to the conflicting use of this field in earlier specifications. tj: The reason we need this is because some devices which don't support READ LOG PAGE lock up after getting issued that command.

[libata] support for > 512 byte sectors (e.g. 4K Native) This change enables my x86 machine to recognize and talk to a "Native 4K" SATA device. When I started working on this, I didn't know Matthew Wilcox had posted a similar patch 2 years ago: http://git.kernel.org/?p=linux/kernel/git/willy/ata.git;a=shortlog;h=refs/heads/ata-large-sectors Gwendal Grignou pointed me at the the above code and small portions of this patch include Matthew's work. That's why Mathew is first on the "Signed-off-by:". I've NOT included his use of a bitmap to determine 512 vs Native for ATA command block size - just used a simple table. And bugs are almost certainly mine. Lastly, the patch has been tested with a native 4K 'Engineering Sample' drive provided by Hitachi GST.

libata: add command name parsing for error output 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.

libata: track SLEEP state and issue SRST to wake it up ATA devices in SLEEP mode don't respond to any commands. SRST is necessary to wake it up. Till now, when a command is issued to a device in SLEEP mode, the command times out, which makes EH reset the device and retry the command after that, causing a long delay.

scsi: ata: libata: Handle completion of CDL commands using policy 0xD A CDL timeout for policy 0xF is defined as a NCQ error, just with a CDL specific sk/asc/ascq in the sense data. Therefore, the existing code in libata does not need to be modified to handle a policy 0xF CDL timeout. For Command Duration Limits policy 0xD: The device shall complete the command without error with the additional sense code set to DATA CURRENTLY UNAVAILABLE. Since a CDL timeout for policy 0xD is not an error, we cannot use the NCQ Command Error log (10h). Instead, we need to read the Sense Data for Successful NCQ Commands log (0Fh). In the success case, just like in the error case, we cannot simply read a log page from the interrupt handler itself, since reading a log page involves sending a READ LOG DMA EXT or READ LOG EXT command. Therefore, we add a new EH action ATA_EH_GET_SUCCESS_SENSE. When a command completes without error, and when the ATA_SENSE bit is set, this new action is set as pending, and EH is scheduled. This way, similar to the NCQ error case, the log page will be read from EH context. An alternative would have been to add a new kthread or workqueue to handle this. However, extending EH can be done with minimal changes and avoids the need to synchronize a new kthread/workqueue with EH.

ata: libata-core: Fix ata_dev_config_cpr() The concurrent positioning ranges log page 47h is a general purpose log page and not a subpage of the indentify device log. Using ata_identify_page_supported() to test for concurrent positioning ranges support is thus wrong. ata_log_supported() must be used. Furthermore, unlike other advanced ATA features (e.g. NCQ priority), accesses to the concurrent positioning ranges log page are not gated by a feature bit from the device IDENTIFY data. Since many older drives react badly to the READ LOG EXT and/or READ LOG DMA EXT commands isued to read device log pages, avoid problems with older drives by limiting the concurrent positioning ranges support detection to drives implementing at least the ACS-4 ATA standard (major version 11). This additional condition effectively turns ata_dev_config_cpr() into a nop for older drives, avoiding problems in the field.

scsi: ata: libata: Add ATA feature control sub-page translation Add support for the ATA feature control sub-page of the control mode page to enable/disable the command duration limits feature using the cdl_ctrl field of the ATA feature control sub-page. Both mode sense and mode select translation are supported. For mode sense, the ata device flag ATA_DFLAG_CDL_ENABLED is used to cache the status of the command duration limits feature. Enabling this feature is done using a SET FEATURES command with a cdl action set to 1 when the page cdl_ctrl field value is 0x2 (T2A and T2B pages supported). If this field is 0, CDL is disabled using the SET FEATURES command with a cdl action set to 0. Since a device CDL and NCQ priority features should not be used simultaneously, ata_mselect_control_ata_feature() returns an error when attempting to enable CDL with the device priority feature enabled. Conversely, the function ata_ncq_prio_enable_store() used to enable the use of the device NCQ priority feature through sysfs is modified to return an error if the device CDL feature is enabled.

The total 15s is too short for some drives to complete spinup (e.g. drives with a large indirection table stored on media), resulting in ata_dev_read_id to fail twice on the execution of SETFEATURES_SPINUP. For this feature, allow a larger default timeout of 30 seconds. However, in the same spirit as with the timeout of other feature subcommands, do not ignore ata_probe_timeout if it is set).

libata: Handle drives that require a spin-up command before first access (S)ATA drives can be configured for "power-up in standby", a mode whereby a specific "spin up now!" command is required before the first media access. Currently, a drive with this feature enabled can not be used at all with libata, and once in this mode, the drive becomes a doorstop. The older drivers/ide subsystem at least enumerates the drive, so that it can be woken up after the fact from a userspace HDIO_* command, but not libata. This patch adds support to libata for the "power-up in standby" mode where a "spin up now!" command (SET_FEATURES) is needed. With this, libata will recognize such drives, spin them up, and then re-IDENTIFY them if necessary to get a full/complete set of drive features data. Drives in this state are determined by looking for special values in id[2], as documented in the current ATA specs.

scsi: ata: libata: Add ATA feature control sub-page translation Add support for the ATA feature control sub-page of the control mode page to enable/disable the command duration limits feature using the cdl_ctrl field of the ATA feature control sub-page. Both mode sense and mode select translation are supported. For mode sense, the ata device flag ATA_DFLAG_CDL_ENABLED is used to cache the status of the command duration limits feature. Enabling this feature is done using a SET FEATURES command with a cdl action set to 1 when the page cdl_ctrl field value is 0x2 (T2A and T2B pages supported). If this field is 0, CDL is disabled using the SET FEATURES command with a cdl action set to 0. Since a device CDL and NCQ priority features should not be used simultaneously, ata_mselect_control_ata_feature() returns an error when attempting to enable CDL with the device priority feature enabled. Conversely, the function ata_ncq_prio_enable_store() used to enable the use of the device NCQ priority feature through sysfs is modified to return an error if the device CDL feature is enabled.

ahci: implement aggressive SATA device sleep support Device Sleep is a feature as described in AHCI 1.3.1 Technical Proposal. This feature enables an HBA and SATA storage device to enter the DevSleep interface state, enabling lower power SATA-based systems. Aggressive Device Sleep enables the HBA to assert the DEVSLP signal as soon as there are no commands outstanding to the device and the port specific Device Sleep idle timer has expired. This enables autonomous entry into the DevSleep interface state without waiting for software in power sensitive systems. This patch enables Aggressive Device Sleep only if both host controller and device support it. Tested on AMD reference board together with Device Sleep supported device sample.

scsi: ata: libata: Handle completion of CDL commands using policy 0xD A CDL timeout for policy 0xF is defined as a NCQ error, just with a CDL specific sk/asc/ascq in the sense data. Therefore, the existing code in libata does not need to be modified to handle a policy 0xF CDL timeout. For Command Duration Limits policy 0xD: The device shall complete the command without error with the additional sense code set to DATA CURRENTLY UNAVAILABLE. Since a CDL timeout for policy 0xD is not an error, we cannot use the NCQ Command Error log (10h). Instead, we need to read the Sense Data for Successful NCQ Commands log (0Fh). In the success case, just like in the error case, we cannot simply read a log page from the interrupt handler itself, since reading a log page involves sending a READ LOG DMA EXT or READ LOG EXT command. Therefore, we add a new EH action ATA_EH_GET_SUCCESS_SENSE. When a command completes without error, and when the ATA_SENSE bit is set, this new action is set as pending, and EH is scheduled. This way, similar to the NCQ error case, the log page will be read from EH context. An alternative would have been to add a new kthread or workqueue to handle this. However, extending EH can be done with minimal changes and avoids the need to synchronize a new kthread/workqueue with EH.

libata: add ATA_CBL_PATA_IGN ATA_CBL_PATA_UNK indicates that the cable type can't be determined from the host side and might be either 80c or 40c. libata applies drive or other generic limit in this case. However, there are controllers where both host and drive side detections are misimplemented and the driver has to rely solely on private method - peeking BIOS or ACPI configuration or using some other private mechanism. This patch adds ATA_CBL_PATA_IGN which tells libata to ignore the cable type completely and just let the LLD determine the transfer mode via host transfer mode masks and ->mode_filter().

libata: fix HDIO_GET_32BIT ioctl As reported by Soohoon Lee, the HDIO_GET_32BIT ioctl does not work correctly in compat mode with libata. I have investigated the issue further and found multiple problems that all appeared with the same commit that originally introduced HDIO_GET_32BIT handling in libata back in linux-2.6.8 and presumably also linux-2.4, as the code uses "copy_to_user(arg, &val, 1)" to copy a 'long' variable containing either 0 or 1 to user space. The problems with this are: * On big-endian machines, this will always write a zero because it stores the wrong byte into user space. * In compat mode, the upper three bytes of the variable are updated by the compat_hdio_ioctl() function, but they now contain uninitialized stack data. * The hdparm tool calling this ioctl uses a 'static long' variable to store the result. This means at least the upper bytes are initialized to zero, but calling another ioctl like HDIO_GET_MULTCOUNT would fill them with data that remains stale when the low byte is overwritten. Fortunately libata doesn't implement any of the affected ioctl commands, so this would only happen when we query both an IDE and an ATA device in the same command such as "hdparm -N -c /dev/hda /dev/sda" * The libata code for unknown reasons started using ATA_IOC_GET_IO32 and ATA_IOC_SET_IO32 as aliases for HDIO_GET_32BIT and HDIO_SET_32BIT, while the ioctl commands that were added later use the normal HDIO_* names. This is harmless but rather confusing. This addresses all four issues by changing the code to use put_user() on an 'unsigned long' variable in HDIO_GET_32BIT, like the IDE subsystem does, and by clarifying the names of the ioctl commands.

ata: libata-scsi: Fix system suspend for a security locked drive Commit cf3fc037623c ("ata: libata-scsi: Fix ata_to_sense_error() status handling") fixed ata_to_sense_error() to properly generate sense key ABORTED COMMAND (without any additional sense code), instead of the previous bogus sense key ILLEGAL REQUEST with the additional sense code UNALIGNED WRITE COMMAND, for a failed command. However, this broke suspend for Security locked drives (drives that have Security enabled, and have not been Security unlocked by boot firmware). The reason for this is that the SCSI disk driver, for the Synchronize Cache command only, treats any sense data with sense key ILLEGAL REQUEST as a successful command (regardless of ASC / ASCQ). After commit cf3fc037623c ("ata: libata-scsi: Fix ata_to_sense_error() status handling") the code that treats any sense data with sense key ILLEGAL REQUEST as a successful command is no longer applicable, so the command fails, which causes the system suspend to be aborted: sd 1:0:0:0: PM: dpm_run_callback(): scsi_bus_suspend returns -5 sd 1:0:0:0: PM: failed to suspend async: error -5 PM: Some devices failed to suspend, or early wake event detected To make suspend work once again, for a Security locked device only, return sense data LOGICAL UNIT ACCESS NOT AUTHORIZED, the actual sense data which a real SCSI device would have returned if locked. The SCSI disk driver treats this sense data as a successful command.

If this word is not supported, the word shall be cleared to zero. (This text also exists in really old ACS standards, e.g. ACS-3.) The problem with ata_id_has_dipm() is that the while it performs a check against 0 and 0xffff, it performs the check against ATA_ID_FEATURE_SUPP (word 78), the same word where the feature bit is stored. Fix this by performing the check against ATA_ID_SATA_CAPABILITY (word 76), like required by the spec. The feature bit check itself is of course still performed against ATA_ID_FEATURE_SUPP (word 78). Additionally, move the macro to the other ATA_ID_FEATURE_SUPP macros (which already have this check), thus making it more likely that the next ATA_ID_FEATURE_SUPP macro that is added will include this check.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[PATCH] libata: interrupt driven pio for libata-core - add PIO_ST_FIRST for the state before sending ATAPI CDB or sending "ATA PIO data out" first data block. - add ATA_TFLAG_POLLING and ATA_DFLAG_CDB_INTR flags - remove the ATA_FLAG_NOINTR flag since the interrupt handler is now aware of the states - modify ata_pio_sector() and atapi_pio_bytes() to work in the interrupt context - modify the ata_host_intr() to handle PIO interrupts - modify ata_qc_issue_prot() to initialize states - atapi_packet_task() changed to handle "ATA PIO data out" first data block - support the pre-ATA4 ATAPI device which raise interrupt when ready to receive CDB Signed-off-by: Albert Lee <albertcc@tw.ibm.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

[libata] Link power management infrastructure Device Initiated Power Management, which is defined in SATA 2.5 can be enabled for disks which support it. This patch enables DIPM when the user sets the link power management policy to "min_power". Additionally, libata drivers can define a function (enable_pm) that will perform hardware specific actions to enable whatever power management policy the user set up for Host Initiated Power management (HIPM). This power management policy will be activated after all disks have been enumerated and intialized. Drivers should also define disable_pm, which will turn off link power management, but not change link power management policy.

When I started working on this, I didn't know Matthew Wilcox had posted a similar patch 2 years ago: http://git.kernel.org/?p=linux/kernel/git/willy/ata.git;a=shortlog;h=refs/heads/ata-large-sectors Gwendal Grignou pointed me at the the above code and small portions of this patch include Matthew's work. That's why Mathew is first on the "Signed-off-by:". I've NOT included his use of a bitmap to determine 512 vs Native for ATA command block size - just used a simple table.

libata: Disable ATA8-ACS proposed Trusted Computing features by default Historically word 48 in the identify data was used to mean 32bit I/O was supported for VLB IDE etc. ATA8 reassigns this word to the Trusted Computing Group, where it is used for TCG features. This means that an ATA8 TCG drive is going to trigger 32bit I/O on some systems which will be funny. Anyway we need to sort this out ready for ATA8 so: - Reorder the ata.h header a bit so the ata_version function occurs early in it - Make dword_io check the ATA version - Add an ATA8 version checking TCG presence test While we are at it the current drafts have a flaw where it may not be possible to disable TCG features at boot (and opt out of the trusted model) as TCG intends because it relies on presence of a different optional feature (DCS). Handle this in software by refusing the TCG commands if libata.allow_tpm is not set. (We must make it possible as some environments such as proprietary VDR devices will doubtless want to use it to lock up content) Finally as with CPRM print a warning so that the user knows they may not be able to full access and use the device.

libata: check for trusted computing in IDENTIFY DEVICE data ATA-8 and later mirrors the TRUSTED COMPUTING SUPPORTED bit in word 48 of the IDENTIFY DEVICE data. Check this before issuing a READ LOG PAGE command to avoid issues with buggy devices. The only downside is that we can't support Security Send / Receive for a device with an older revision due to the conflicting use of this field in earlier specifications. tj: The reason we need this is because some devices which don't support READ LOG PAGE lock up after getting issued that command.

libata: Media rotation rate and form factor heuristics This patch provides new heuristics for parsing both the form factor and media rotation rate ATA IDENFITY words. The reported ATA version must be 7 or greater and the device must return values defined as valid in the standard. Only then are the characteristics reported to SCSI via the VPD B1 page. This seems like a reasonable compromise to me considering that we have been shipping several kernel releases that key off the rotation rate bit without any version checking whatsoever.

ata: Detect Delkin Devices compact flash I have a Delkin Devices compact flash card that isn't being recognized using the SATA/PATA drivers. The card is recognized and works with the deprecated ATA drivers. The error I am seeing is: ata1.00: failed to IDENTIFY (device reports invalid type, err_mask=0x0) I tracked it down to ata_id_is_cfa() in include/linux/ata.h. The Delkin card has id[0] set to 0x844a and id[83] set to 0. This isn't what the kernel expects and is probably incorrect. The simplest work-around is to add a check for 0x844a to ata_id_is_cfa().

libata: Use integer return value for atapi_command_packet_set The function returns type of ATAPI drives so it should return integer value. The commit 4dce8ba94c7 (libata: Use 'bool' return value for ata_id_XXX) since v2.6.39 changed the type of return value from int to bool, the change would cause all of the ATAPI class drives to be treated as TYPE_TAPE and the max_sectors of the drives to be set to 65535 because of the commit f8d8e5799b7(libata: increase 128 KB / cmd limit for ATAPI tape drives), for the function would return true for all ATAPI class drives and the TYPE_TAPE is defined as 0x01.

libata: increase 128 KB / cmd limit for ATAPI tape drives Commands sent to ATAPI tape drives via the SCSI generic (sg) driver are limited in the amount of data that they can transfer by the max_sectors value. The max_sectors value is currently calculated according to the command set for disk drives, which doesn't apply to tape drives. The default max_sectors value of 256 limits ATAPI tape drive commands to 128 KB. This patch against 2.6.24-rc1 increases the max_sectors value for tape drives to 65535, which permits tape drive commands to transfer just under 32 MB. Tested with a SuperMicro PDSME motherboard, AHCI, and a Sony SDX-570V SATA tape drive. Note that some of the chipset drivers also set their own max_sectors value, which may override the value set in libata-core. I don't have any of these chipsets to test, so I didn't go messing with them. Also, ATAPI devices other than tape drives may benefit from similar changes, but I have only tape drives and disk drives to test.

libata: automatically use DMADIR if drive/bridge requires it Back in 2.6.17-rc2, a libata module parameter was added for atapi_dmadir. That's nice, but most SATA devices which need it will tell us about it in their IDENTIFY PACKET response, as bit-15 of word-62 of the returned data (as per ATA7, ATA8 specifications). So for those which specify it, we should automatically use the DMADIR bit. Otherwise, disc writing will fail by default on many SATA-ATAPI drives. This patch adds ATA_DFLAG_DMADIR and make ata_dev_configure() set it if atapi_dmadir is set or identify data indicates DMADIR is necessary. atapi_xlat() is converted to check ATA_DFLAG_DMADIR before setting DMADIR.

libata: Fix accesses at LBA28 boundary (old bug, but nasty) (v2) Most drives from Seagate, Hitachi, and possibly other brands, do not allow LBA28 access to sector number 0x0fffffff (2^28 - 1). So instead use LBA48 for such accesses. This bug could bite a lot of systems, especially when the user has taken care to align partitions to 4KB boundaries. On misaligned systems, it is less likely to be encountered, since a 4KB read would end at 0x10000000 rather than at 0x0fffffff.
