* ata: ahci: Clean up sysfs file on errorNiklas Cassel2024-06-301-5/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | .probe() (ahci_init_one()) calls sysfs_add_file_to_group(), however, if probe() fails after this call, we currently never call sysfs_remove_file_from_group(). (The sysfs_remove_file_from_group() call in .remove() (ahci_remove_one()) does not help, as .remove() is not called on .probe() error.) Thus, if probe() fails after the sysfs_add_file_to_group() call, the next time we insmod the module we will get: sysfs: cannot create duplicate filename '/devices/pci0000:00/0000:00:04.0/remapped_nvme' CPU: 11 PID: 954 Comm: modprobe Not tainted 6.10.0-rc5 #43 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.3-2.fc40 04/01/2014 Call Trace: <TASK> dump_stack_lvl+0x5d/0x80 sysfs_warn_dup.cold+0x17/0x23 sysfs_add_file_mode_ns+0x11a/0x130 sysfs_add_file_to_group+0x7e/0xc0 ahci_init_one+0x31f/0xd40 [ahci] Fixes: 894fba7f434a ("ata: ahci: Add sysfs attribute to show remapped NVMe device count") Cc: stable@vger.kernel.org Reviewed-by: Damien Le Moal <dlemoal@kernel.org> Reviewed-by: Hannes Reinecke <hare@suse.de> Link: https://lore.kernel.org/r/20240629124210.181537-10-cassel@kernel.org Signed-off-by: Niklas Cassel <cassel@kernel.org>

* ata: ahci: Do not enable LPM if no LPM states are supported by the HBANiklas Cassel2024-06-191-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | LPM consists of HIPM (host initiated power management) and DIPM (device initiated power management). ata_eh_set_lpm() will only enable HIPM if both the HBA and the device supports it. However, DIPM will be enabled as long as the device supports it. The HBA will later reject the device's request to enter a power state that it does not support (Slumber/Partial/DevSleep) (DevSleep is never initiated by the device). For a HBA that doesn't support any LPM states, simply don't set a LPM policy such that all the HIPM/DIPM probing/enabling will be skipped. Not enabling HIPM or DIPM in the first place is safer than relying on the device following the AHCI specification and respecting the NAK. (There are comments in the code that some devices misbehave when receiving a NAK.) Performing this check in ahci_update_initial_lpm_policy() also has the advantage that a HBA that doesn't support any LPM states will take the exact same code paths as a port that is external/hot plug capable. Side note: the port in ata_port_dbg() has not been given a unique id yet, but this is not overly important as the debug print is disabled unless explicitly enabled using dynamic debug. A follow-up series will make sure that the unique id assignment will be done earlier. For now, the important thing is that the function returns before setting the LPM policy.

* ata: libata-scsi: Set the RMB bit only for removable media devicesDamien Le Moal2024-06-141-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SCSI Removable Media Bit (RMB) should only be set for removable media, where the device stays and the media changes, e.g. CD-ROM or floppy. The ATA removable media device bit is obsoleted since ATA-8 ACS (2006), but before that it was used to indicate that the device can have its media removed (while the device stays). Commit 8a3e33cf92c7 ("ata: ahci: find eSATA ports and flag them as removable") introduced a change to set the RMB bit if the port has either the eSATA bit or the hot-plug capable bit set. The reasoning was that the author wanted his eSATA ports to get treated like a USB stick. This is however wrong. See "20-082r23SPC-6: Removable Medium Bit Expectations" which has since been integrated to SPC, which states that: """ Reports have been received that some USB Memory Stick device servers set the removable medium (RMB) bit to one. The rub comes when the medium is actually removed, because... The device server is removed concurrently with the medium removal. If there is no device server, then there is no device server that is waiting to have removable medium inserted. Sufficient numbers of SCSI analysts see such a device: - not as a device that supports removable medium; but - as a removable, hot pluggable device. """ The definition of the RMB bit in the SPC specification has since been clarified to match this. Thus, a USB stick should not have the RMB bit set (and neither shall an eSATA nor a hot-plug capable port). Commit dc8b4afc4a04 ("ata: ahci: don't mark HotPlugCapable Ports as external/removable") then changed so that the RMB bit is only set for the eSATA bit (and not for the hot-plug capable bit), because of a lot of bug reports of SATA devices were being automounted by udisks. However, treating eSATA and hot-plug capable ports differently is not correct. From the AHCI 1.3.1 spec: Hot Plug Capable Port (HPCP): When set to '1', indicates that this port's signal and power connectors are externally accessible via a joint signal and power connector for blindmate device hot plug. So a hot-plug capable port is an external port, just like commit 45b96d65ec68 ("ata: ahci: a hotplug capable port is an external port") claims. In order to not violate the SPC specification, modify the SCSI INQUIRY data to only set the RMB bit if the ATA device can have its media removed. This fixes a reported problem where GNOME/udisks was automounting devices connected to hot-plug capable ports.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The pata_macio driver advertises a max_segment_size of 0xff00, because the hardware doesn't cope with requests >= 64K. However the SCSI core requires max_segment_size to be at least PAGE_SIZE, which is a problem for pata_macio when the kernel is built with 64K pages.

Because of the way that the Intel PCS quirk was implemented, having an explicit entry in the ahci_pci_tbl caused the Intel PCS quirk to be applied. (The quirk was not being applied if there was no explict entry.) Thus, entries that were added to the ahci_pci_tbl also got the Intel PCS quirk applied. The quirk was cleaned up in commit 7edbb6059274 ("ahci: clean up intel_pcs_quirk"), such that it is clear which entries that actually applies the Intel PCS quirk. Newer Intel AHCI controllers do not need the Intel PCS quirk, and applying it when not needed actually breaks some platforms. Do not apply the Intel PCS quirk for Intel Alder Lake. This is in line with how things worked before commit b8b8b4e0c052 ("ata: ahci: Add Intel Alder Lake-P AHCI controller to low power chipsets list"), such that certain platforms using Intel Alder Lake will work once again.

The excess ports are "virtual" to hide port multiplier devices and probing these ports takes time. However, these commits caused a regression for users that do use PMP devices, as the ATA devices connected to the PMP cannot be scanned. These commits have thus been reverted by commit 6cd8adc3e18 ("ahci: asm1064: asm1166: don't limit reported ports") to allow the discovery of devices connected through a port multiplier. But this revert re-introduced the long boot times for users that do not use a port multiplier setup. This patch adds the mask_port_map ahci module parameter to allow users to manually specify port map masks for controllers. In the case of the ASMedia 1166 and 1064 controllers, users that do not have port multiplier devices can mask the excess virtual ports exposed by the controller to speedup port scanning, thus reducing boot time. The mask_port_map parameter accepts 2 different formats: - mask_port_map=<mask> This applies the same mask to all AHCI controllers present in the system. This format is convenient for small systems that have only a single AHCI controller. - mask_port_map=<pci_dev>=<mask>,<pci_dev>=mask,... This applies the specified masks only to the PCI device listed. The <pci_dev> field is a regular PCI device ID (domain:bus:dev.func). This ID can be seen following "ahci" in the kernel messages. E.g. for "ahci 0000:01:00.0: 2/2 ports implemented (port mask 0x3)", the <pci_dev> field is "0000:01:00.0". When used, the function ahci_save_initial_config() indicates that a port map mask was applied with the message "masking port_map ...". E.g.: without a mask: modprobe ahci dmesg | grep ahci ... ahci 0000:00:17.0: AHCI vers 0001.0301, 32 command slots, 6 Gbps, SATA mode ahci 0000:00:17.0: (0000:00:17.0) 8/8 ports implemented (port mask 0xff) With a mask: modprobe ahci mask_port_map=0000:00:17.0=0x1 dmesg | grep ahci ... ahci 0000:00:17.0: masking port_map 0xff -> 0x1 ahci 0000:00:17.0: AHCI vers 0001.0301, 32 command slots, 6 Gbps, SATA mode ahci 0000:00:17.0: (0000:00:17.0) 1/8 ports implemented (port mask 0x1) Signed-off-by: Damien Le Moal <dlemoal@kernel.org> Reviewed-by: Niklas Cassel <cassel@kernel.org>

* | scsi: sd: Fix TCG OPAL unlock on system resumeDamien Le Moal2024-03-252-1/+13
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 3cc2ffe5c16d ("scsi: sd: Differentiate system and runtime start/stop management") introduced the manage_system_start_stop scsi_device flag to allow libata to indicate to the SCSI disk driver that nothing should be done when resuming a disk on system resume. This change turned the execution of sd_resume() into a no-op for ATA devices on system resume. While this solved deadlock issues during device resume, this change also wrongly removed the execution of opal_unlock_from_suspend(). As a result, devices with TCG OPAL locking enabled remain locked and inaccessible after a system resume from sleep. To fix this issue, introduce the SCSI driver resume method and implement it with the sd_resume() function calling opal_unlock_from_suspend(). The former sd_resume() function is renamed to sd_resume_common() and modified to call the new sd_resume() function. For non-ATA devices, this result in no functional changes. In order for libata to explicitly execute sd_resume() when a device is resumed during system restart, the function scsi_resume_device() is introduced. libata calls this function from the revalidation work executed on devie resume, a state that is indicated with the new device flag ATA_DFLAG_RESUMING. Doing so, locked TCG OPAL enabled devices are unlocked on resume, allowing normal operation.

* ahci: asm1064: asm1166: don't limit reported portsConrad Kostecki2024-03-191-13/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, patches have been added to limit the reported count of SATA ports for asm1064 and asm1166 SATA controllers, as those controllers do report more ports than physically having. While it is allowed to report more ports than physically having in CAP.NP, it is not allowed to report more ports than physically having in the PI (Ports Implemented) register, which is what these HBAs do. (This is a AHCI spec violation.) Unfortunately, it seems that the PMP implementation in these ASMedia HBAs is also violating the AHCI and SATA-IO PMP specification. What these HBAs do is that they do not report that they support PMP (CAP.SPM (Supports Port Multiplier) is not set). Instead, they have decided to add extra "virtual" ports in the PI register that is used if a port multiplier is connected to any of the physical ports of the HBA. Enumerating the devices behind the PMP as specified in the AHCI and SATA-IO specifications, by using PMP READ and PMP WRITE commands to the physical ports of the HBA is not possible, you have to use the "virtual" ports. This is of course bad, because this gives us no way to detect the device and vendor ID of the PMP actually connected to the HBA, which means that we can not apply the proper PMP quirks for the PMP that is connected to the HBA. Limiting the port map will thus stop these controllers from working with SATA Port Multipliers. This patch reverts both patches for asm1064 and asm1166, so old behavior is restored and SATA PMP will work again, but it will also reintroduce the (minutes long) extra boot time for the ASMedia controllers that do not have a PMP connected (either on the PCIe card itself, or an external PMP). However, a longer boot time for some, is the lesser evil compared to some other users not being able to detect their drives at all.

Now when we make sure that we won't enable LPM for external ports, we can always set the LPM policy to CONFIG_SATA_MOBILE_LPM_POLICY for internal ports. There is thus no longer any need for the board type board_ahci_low_power, so it can be removed. (As before, LPM features not supported by the HBA and/or the device will not be enabled, regardless of the LPM policy Kconfig) (Mario Limonciello) Note that the default CONFIG_SATA_MOBILE_LPM_POLICY value is still 0 (which will not try to enable any LPM features), however, most Linux distributions override this and set it to 3 (Medium power with DIPM). We intend to change the default to 3 in the coming cycles, but we will wait a cycle or two. - Add board type board_ahci_pcs_quirk and make all legacy Intel platforms use it. The Intel PCS quirk was being applied to basically all Intel platforms, which caused some issues (the device failing to come back after a reset), when being applied to newer Intel platforms where it shouldn't have been applied.

It claims that board_ahci_pcs7 is needing the quirk, but in fact, the logic implemented in ahci_intel_pcs_quirk() is the exact opposite, only board_ahci_pcs7 is _excluded_ from the quirk. This way of implementing a quirk is unconventional in several ways: First of all because it has a board ID for which the quirk should _not_ be applied (board_ahci_pcs7), instead of the usual way where we have a board ID for which the quirk should be applied. The second reason is that other than only excluding board_ahci_pcs7 from the quirk, PCI devices that make use of the generic entry in ahci_pci_tbl (which matches on AHCI class code) are also excluded. This can of course lead to very subtle breakage, and did indeed do so in: commit 104ff59af73a ("ata: ahci: Add Tiger Lake UP{3,4} AHCI controller"), which added an explicit entry with board_ahci_low_power to ahci_pci_tbl. This caused many users to complain that their SATA drives disappeared. The logical assumption was of course that the issue was related to LPM, and was therefore reverted in commit 6210038aeaf4 ("ata: ahci: Revert "ata: ahci: Add Tiger Lake UP{3,4} AHCI controller""). It took a lot of time to figure out that this was all completely unrelated to LPM, and was instead caused by an unconventional Intel quirk. Clean up the quirk so that it behaves like other quirks, i.e. define a board where the quirk is applied. Platforms that were using board_ahci_pcs7 are converted to use board_ahci, this is safe since the boards were identical, and board_ahci_pcs7 did not define any custom port_ops. This way, new Intel platforms can be added using the correct "board_ahci" board, without getting any unexpected quirks applied. This means that we currently have some modern platforms defined that are using the Intel PCS quirk, but that is identical to the behavior that was there before this commit. No functional changes intended.

Software should perform the following initialization on a port after a device is attached: -Set PxSCTL.IPM to 3h to disable interface power management state transitions. -Set PxCMD.ALPE to ‘0’ to disable aggressive power management. -Ensure PxIE.PRCE is set to ‘1’ to enable interrupts on hot plug removals. -Disable device initiated interface power management by issuing the appropriate SET FEATURES command." Further, AHCI 1.3.3, 7.3 Native Hot Plug Support states: "The HBA shall set the PxSERR.DIAG.X bit to ‘1’ when a COMINIT is received from the device. Hot plug insertions are detected via the PxIS.PCS bit that directly reflects the PxSERR.DIAG.X bit. The HBA shall set the PxSERR.DIAG.N bit to ‘1’ when the HBA’s internal PhyRdy signal changes state. Hot plug removals are detected via the PxIS.PRCS bit that directly reflects the PxSERR.DIAG.N bit. Note that PxSERR.DIAG.N is also set to ‘1’ on insertions and during interface power management entry/exit." ahci_set_lpm() already disables the PxIS.PRCS interrupt if setting a LPM policy != ATA_LPM_MAX_POWER, so we cannot detect hot plug removals when LPM policy != ATA_LPM_MAX_POWER. We do have PxIS.PCS interrupt enabled even for LPM policy != ATA_LPM_MAX_POWER, so we should theoretically still be able to detect hot plug insertions even when LPM is enabled. However, in practise, for LPM policy ATA_LPM_MED_POWER_WITH_DIPM, ATA_LPM_MIN_POWER_WITH_PARTIAL, and ATA_LPM_MIN_POWER, if there is no link enabled, sata_link_scr_lpm() will set SControl.DET = 0x4, which will transition the port to the "P:Offline" state. The P:Offline mode is described in SATA Gold 3.5a: 4.1.1.103 Phy offline: "In this mode the host Phy is forced off and the host Phy does not recognize nor respond to COMINIT or COMWAKE. This mode is entered by setting the DET field of the SControl register to 0100b. This is a mechanism for the host to turn off its Phy." So in the P:Offline state the PHY does not recognize the unsolicited COMINIT which is sent on a hot plug insertion. While we could change sata_link_scr_lpm() to never power off an external port for LPM policy != ATA_LPM_MAX_POWER (in order be able to handle hot plug insertions), we still would not be able to handle hot plug removals. Thus, simply modify ahci_update_initial_lpm_policy() to not enable LPM if the port advertises itself as an external port, as this function is already being used to set/override the initial LPM policy.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For regular system shutdown, ata_dev_power_set_standby() will be executed twice: once the scsi device is removed and another when ata_pci_shutdown_one() executes and EH completes unloading the devices. Make the second call to ata_dev_power_set_standby() do nothing by using ata_dev_power_is_active() and return if the device is already in standby.

To fix introduce the function ceva_ahci_platform_enable_resources() which is a customized version of ahci_platform_enable_resources() and inline with SATA IP programming sequence it does: - Assert SATA reset - Program PS GTR phy - Bring SATA by de-asserting the reset - Wait for GT lane PLL to be locked ceva_ahci_platform_enable_resources() is also used in the resume path as the same SATA programming sequence (as in probe) should be followed. Also cleanup the mixed usage of ahci_platform_enable_resources() and custom implementation in the probe function as both are not required.
