2023-01-31ata: pata_parport: add driver (PARIDE replacement)Ondrej Zary8-17/+968
The pata_parport is a libata-based replacement of the old PARIDE subsystem - driver for parallel port IDE devices. It uses the original paride low-level protocol drivers but does not need the high-level drivers (pd, pcd, pf, pt, pg). The IDE devices behind parallel port adapters are handled by the ATA layer. This will allow paride and its high-level drivers to be removed. Unfortunately, libata drivers cannot sleep so pata_parport claims parport before activating the ata host and keeps it claimed (and protocol connected) until the ata host is removed. This means that no devices can be chained (neither other pata_parport devices nor a printer). paride and pata_parport are mutually exclusive because the compiled protocol drivers are incompatible. Tested with: - Imation SuperDisk LS-120 and HP C4381A (EPAT) - Freecom Parallel CD (FRPW) - Toshiba Mobile CD-RW 2793008 w/Freecom Parallel Cable rev.903 (FRIQ) - Backpack CD-RW 222011 and CD-RW 19350 (BPCK6) The following bugs in low-level protocol drivers were found and will be fixed later: Note: EPP-32 mode is buggy in EPAT - and also in all other protocol drivers - they don't handle non-multiple-of-4 block transfers correctly. This causes problems with LS-120 drive. There is also another bug in EPAT: EPP modes don't work unless a 4-bit or 8-bit mode is used first (probably some initialization missing?). Once the device is initialized, EPP works until power cycle. So after device power on, you have to: echo "parport0 epat 0" >/sys/bus/pata_parport/new_device echo pata_parport.0 >/sys/bus/pata_parport/delete_device echo "parport0 epat 4" >/sys/bus/pata_parport/new_device (autoprobe will initialize correctly as it tries the slowest modes first but you'll get the broken EPP-32 mode) Note: EPP modes are buggy in FRPW, only modes 0 and 1 work.

2023-01-14ata: libata: exclude FUA support for known buggy drivesDamien Le Moal1-0/+3
Thread [1] reported back in 2012 problems with enabling FUA for 3 different drives. Add these drives to ata_device_blacklist[] to mark them with the ATA_HORKAGE_NO_FUA flag. To be conservative and avoid problems on old systems, the model number for the three new entries are defined as to widely match all drives in the same product line.

2023-01-14ata: libata: Fix FUA handling in ata_build_rw_tf()Damien Le Moal1-3/+5
If a user issues a write command with the FUA bit set for a device with NCQ support disabled (that is, the device queue depth was set to 1), the LBA 48 command WRITE DMA FUA EXT must be used. However, ata_build_rw_tf() ignores this and first tests if LBA 28 can be used based on the write command sector and number of blocks. That is, for small FUA writes at low LBAs, ata_rwcmd_protocol() will cause the write to fail. Fix this by preventing the use of LBA 28 for any FUA write request. Given that the WRITE MULTI FUA EXT command is marked as obsolete in the ATA specification since ACS-3 (published in 2013), remove the ATA_CMD_WRITE_MULTI_FUA_EXT command from the ata_rw_cmds array.

2023-01-14ata: libata: cleanup fua support detectionDamien Le Moal4-32/+39
Move the detection of a device FUA support from ata_scsiop_mode_sense()/ata_dev_supports_fua() to device scan time in ata_dev_configure(). The function ata_dev_config_fua() is introduced to detect if a device supports FUA and this support is indicated using the new device flag ATA_DFLAG_FUA. In order to blacklist known buggy devices, the horkage flag ATA_HORKAGE_NO_FUA is introduced. Similarly to other horkage flags, the libata.force= arguments "fua" and "nofua" are also introduced to allow a user to control this horkage flag through the "force" libata module parameter. The ATA_DFLAG_FUA device flag is set only and only if all the following conditions are met: * libata.fua module parameter is set to 1 * The device supports the WRITE DMA FUA EXT command, * The device is not marked with the ATA_HORKAGE_NO_FUA flag, either from the blacklist or set by the user with libata.force=nofua * The device supports NCQ (while this is not mandated by the standards, this restriction is introduced to avoid problems with older non-NCQ devices). Enabling or diabling libata FUA support for all devices can now also be done using the "force=[no]fua" module parameter when libata.fua is set to 1.

2023-01-04ata: libata-scsi: do not overwrite SCSI ML and status bytesNiklas Cassel1-4/+4
For SCSI ML byte: In the case where a command is completed via libata EH: irq -> ata_qc_complete() -> ata_qc_schedule_eh() irq done ... -> ata_do_eh() -> ata_eh_link_autopsy() -> ata_eh_finish() -> ata_eh_qc_complete() -> __ata_eh_qc_complete() -> __ata_qc_complete() -> qc->complete_fn() (ata_scsi_qc_complete()) -> ata_qc_done() -> qc->scsidone() (empty stub) ... -> scsi_eh_finish_cmd() -> scsi_eh_flush_done_q() -> scsi_finish_command() ata_eh_link_autopsy() will call ata_eh_analyze_tf(), which calls scsi_check_sense(), which sets the SCSI ML byte. Since ata_scsi_qc_complete() is called after scsi_check_sense() when a command is completed via libata EH, we cannot simply overwrite the SCSI ML byte that was set earlier in the call chain. For SCSI status byte: When a SCSI command is prepared using scsi_prepare_cmd(), it sets cmd->result to 0. (SAM_STAT_GOOD is defined as 0x0). Likewise, when a command is requeued from SCSI EH, scsi_queue_insert() is called, which sets cmd->result to 0. A SCSI command thus always has a GOOD status by default when being sent to libata. If libata fetches sense data from the device, it will call ata_scsi_set_sense(), which will set the status byte to SAM_STAT_CHECK_CONDITION, if the caller deems that the status should be a check condition. ata_scsi_qc_complete() should therefore never overwrite the existing status byte, because if it is != GOOD, it was set by libata itself, for a reason. For the host byte: When libata abort commands, because of a NCQ error, it will schedule SCSI EH for all QCs using blk_abort_request(), which will all end up in scsi_timeout(), which will call scsi_abort_command(). scsi_timeout() sets DID_TIME_OUT regardless if a command was aborted or timed out. If we don't clear the DID_TIME_OUT byte for the QC that caused the NCQ error, that QC will be reported as a timed out command, instead of being reported as a NCQ error. For a command that actually timed out, DID_TIME_OUT would be fine to keep, but libata has its own way of detecting that a command timed out (see ata_scsi_cmd_error_handler()), and sets AC_ERR_TIMEOUT if that is the case. libata will retry timed out commands. We could clear DID_TIME_OUT only for the QC that caused the NCQ error, but since libata has its own way of detecting timeouts, simply clear it always. Note that the existing ata_scsi_qc_complete() code does: cmd->result = SAM_STAT_CHECK_CONDITION or cmd->result = SAM_STAT_GOOD. This WILL clear the host byte. So us clearing the host byte unconditionally is in line with the existing libata behavior.

2023-01-04ata: libata: move NCQ related ATA_DFLAGsNiklas Cassel1-8/+7
ata_dev_configure() starts off by clearing all flags in ATA_DFLAG_CFG_MASK: dev->flags &= ~ATA_DFLAG_CFG_MASK; ata_dev_configure() then calls ata_dev_config_lba() which calls ata_dev_config_ncq(). ata_dev_config_ncq() will set the correct ATA_DFLAGs depending on what is actually supported. Since these flags are set by ata_dev_configure(), they should be in ATA_DFLAG_CFG_MASK and not in ATA_DFLAG_INIT_MASK. ATA_DFLAG_NCQ_PRIO_ENABLED is set via sysfs, is should therefore not be in ATA_DFLAG_CFG_MASK. It also cannot be in ATA_DFLAG_INIT_MASK, because ata_eh_schedule_probe() calls ata_dev_init(), which will clear all flags in ATA_DFLAG_INIT_MASK. This means that ATA_DFLAG_NCQ_PRIO_ENABLED (the value the user sets via sysfs) would get silently cleared if ata_eh_schedule_probe() is called. While that should only happen in certain circumstances, it still doesn't seem right that it can get silently cleared. (ata_dev_config_ncq_prio() will still clear the ATA_DFLAG_NCQ_PRIO_ENABLED flag if ATA_DFLAG_NCQ_PRIO is suddenly no longer supported after a revalidation.) Because of this, move ATA_DFLAG_NCQ_PRIO_ENABLED to be outside of both ATA_DFLAG_CFG_MASK and ATA_DFLAG_INIT_MASK.

2023-01-04ata: libata: respect successfully completed commands during errorsNiklas Cassel1-31/+42
In AHCI specification 1.3.1: "5.5.3 Processing Completed Commands" "For each port that has an interrupt pending: 1. Software determines the cause of the interrupt by reading the PxIS register. It is possible for multiple bits to be set. 2. Software clears appropriate bits in the PxIS register corresponding to the cause of the interrupt. 3. Software clears the interrupt bit in IS.IPS corresponding to the port. 4. If executing non-queued commands, software reads the PxCI register, and compares the current value to the list of commands previously issued by software that are still outstanding. If executing native queued commands, software reads the PxSACT register and compares the current value to the list of commands previously issued by software. Software completes with success any outstanding command whose corresponding bit has been cleared in the respective register. PxCI and PxSACT are volatile registers; software should only use their values to determine commands that have completed, not to determine which commands have previously been issued. 5. If there were errors, noted in the PxIS register, software performs error recovery actions (see section 6.2.2)." The documentation for the PxSACT shadow register in AHCI: "The device clears bits in this field by sending a Set Device Bits FIS to the host. The HBA clears bits in this field that are set to ‘1’ in the SActive field of the Set Device Bits FIS. The HBA only clears bits that correspond to native queued commands that have completed successfully." Additionally, in SATA specification 3.5a: "11.15 FPDMA QUEUED command protocol" "DFPDMAQ11: ERROR Halt command processing and transmit Set Device Bits FIS to host with the ERR bit in Status field set to one, Interrupt bit set to one, ATA error code set to one in the ERROR field, bits in ACT field cleared to zero for any outstanding queued commands, and bits set to one for any successfully completed queued commands that completion notification not yet delivered." I.e. even when the HBA triggers an error interrupt, the HBA will still clear successfully completed commands in PxSACT. Commands that did not complete successfully will still have its bit set in PxSACT. (Which means the command that caused the NCQ error and queued commands that had not yet finished at the time when the NCQ error occurred.) Additionally, for a HBA that does not have the libata flag AHCI_HFLAG_MULTI_MSI set, all ap->locks will point to host->lock, which means that IRQs will be disabled for one port while another port's IRQ handler is running. The HBA will still receive FISes from the device, even if IRQs on the HBA itself are disabled. What can thus e.g. receive a FIS that completes several commands successfully, followed by a FIS that does (or does not) complete additional commands with the error bit set, to indicate that at least one command was aborted. Therefore, modify ahci_handle_port_interrupt() using the new helper ahci_qc_complete() to complete the commands that have already been signaled as successfully through a regular completion SDB FIS, as not doing so would simply cause successfully completed commands to be retried for no good reason.

2023-01-04ata: libata: read the shared status for successful NCQ commands onceNiklas Cassel3-3/+92
Currently, the status is being read for each QC, inside ata_qc_complete(), which means that QCs being completed by ata_qc_complete_multiple() (i.e. multiple QCs completed during a single interrupt), can have different status and error bits set. This is because the FIS Receive Area will get updated as soon as the HBA receives a new FIS from the device in the NCQ case. Here is an example of the problem: ata14.00: ata_qc_complete_multiple: done_mask: 0x180000 qc tag: 19 cmd: 0x61 flags: 0x11b err_mask: 0x0 tf->status: 0x40 qc tag: 20 cmd: 0x61 flags: 0x11b err_mask: 0x0 tf->status: 0x43 A print in ata_qc_complete_multiple(), shows that done_mask is: 0x180000 which means that tag 19 and 20 were completed. Another print in ata_qc_complete(), after the call to fill_result_tf(), shows that tag 19 and 20 have different status values, even though they were completed in the same ata_qc_complete_multiple() call. If PMP is not enabled, simply read the status and error once, before calling ata_qc_complete() for each QC. Without PMP, we know that all QCs must share the same status and error values. If PMP is enabled, we also read the status before calling ata_qc_complete(), however, we still read the status for each QC, since the QCs can belong to different PMP links (which means that the QCs does not necessarily share the same status and error values). Do all this by introducing the new port operation .qc_ncq_fill_rtf. If set, this operation is called in ata_qc_complete_multiple() to set the result tf for all completed QCs signaled by the last SDB FIS received. QCs that have their result tf filled are marked with the new flag ATA_QCFLAG_RTF_FILLED so that any later execution of the qc_fill_rtf port operation does nothing (e.g. when called from ata_qc_complete()).

2023-01-04ata: scsi: rename flag ATA_QCFLAG_FAILED to ATA_QCFLAG_EHNiklas Cassel15-38/+38
The name ATA_QCFLAG_FAILED is misleading since it does not mean that a QC completed in error, or that it didn't complete at all. It means that libata decided to schedule EH for the QC, so the QC is now owned by the libata error handler (EH). The normal execution path is responsible for not accessing a QC owned by EH. libata core enforces the rule by returning NULL from ata_qc_from_tag() for QCs owned by EH. It is quite easy to mistake that a QC marked with ATA_QCFLAG_FAILED was an error. However, a QC that was actually an error is instead indicated by having qc->err_mask set. E.g. when we have a NCQ error, we abort all QCs, which currently will mark all QCs as ATA_QCFLAG_FAILED. However, it will only be a single QC that is an error (i.e. has qc->err_mask set). Rename ATA_QCFLAG_FAILED to ATA_QCFLAG_EH to more clearly highlight that this flag simply means that a QC is now owned by EH. This new name will not mislead to think that the QC was an error (which is instead indicated by having qc->err_mask set). This also makes it more obvious that the EH code skips all QCs that do not have ATA_QCFLAG_EH set (rather than ATA_QCFLAG_FAILED), since the EH code should simply only care about QCs that are owned by EH itself.

2022-12-30drm/i915/dsi: add support for ICL+ native MIPI GPIO sequenceJani Nikula3-3/+95
Starting from ICL, the default for MIPI GPIO sequences seems to be using native GPIOs i.e. GPIOs available in the GPU. These native GPIOs reuse many pins that quite frankly seem scary to poke based on the VBT sequences. We pretty much have to trust that the board is configured such that the relevant HPD, PP_CONTROL and GPIO bits aren't used for anything else. MIPI sequence v4 also adds a flag to fall back to non-native sequences. v5: - Wrap SHOTPLUG_CTL_DDI modification in spin_lock() in icp_irq_handler() too (Ville) - References instead of Closes issue 6131 because this does not fix everything v4: - Wrap SHOTPLUG_CTL_DDI modification in spin_lock_irq() (Ville) v3: - Fix -Wbitwise-conditional-parentheses (kernel test robot <lkp@intel.com>) v2: - Fix HPD pin output set (impacts GPIOs 0 and 5) - Fix GPIO data output direction set (impacts GPIOs 4 and 9) - Reduce register accesses to single intel_de_rwm() References: https://gitlab.freedesktop.org/drm/intel/-/issues/6131 Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20221219105955.4014451-1-jani.nikula@intel.com (cherry picked from commit f087cfe6fcff58044f7aa3b284965af47f472fb0) Cc: stable@vger.kernel.org # 6.1 Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>

2022-12-30kbuild: rpm-pkg: add libelf-devel as alternative for BuildRequiresMasahiro Yamada1-1/+2
Guoqing Jiang reports that openSUSE cannot compile the kernel rpm due to "BuildRequires: elfutils-libelf-devel" added by commit 8818039f959b ("kbuild: add ability to make source rpm buildable using koji"). The relevant package name in openSUSE is libelf-devel. Add it as an alternative package. BTW, if it is impossible to solve the build requirement, the final resort would be: $ make RPMOPTS=--nodeps rpm-pkg This passes --nodeps to the rpmbuild command so it will not verify build dependencies. This is useful to test rpm builds on non-rpm system. On Debian/Ubuntu, for example, you can install rpmbuild by 'apt-get install rpm'. NOTE1: Likewise, it is possible to bypass the build dependency check for debian package builds: $ make DPKG_FLAGS=-d deb-pkg NOTE2: The 'or' operator is supported since RPM 4.13. So, old distros such as CentOS 7 will break. I suggest installing newer rpmbuild in such cases.

2022-12-30kbuild: Fix running modpost with musl libcSamuel Holland1-11/+11
commit 3d57e1b7b1d4 ("kbuild: refactor the prerequisites of the modpost rule") moved 'vmlinux.o' inside modpost-args, possibly before some of the other options. However, getopt() in musl libc follows POSIX and stops looking for options upon reaching the first non-option argument. As a result, the '-T' option is misinterpreted as a positional argument, and the build fails: make -f ./scripts/Makefile.modpost scripts/mod/modpost -E -o Module.symvers vmlinux.o -T modules.order -T: No such file or directory make[1]: *** [scripts/Makefile.modpost:137: Module.symvers] Error 1 make: *** [Makefile:1960: modpost] Error 2 The fix is to move all options before 'vmlinux.o' in modpost-args.

2022-12-30arch: fix broken BuildID for arm64 and riscvMasahiro Yamada1-0/+5
Dennis Gilmore reports that the BuildID is missing in the arm64 vmlinux since commit 994b7ac1697b ("arm64: remove special treatment for the link order of head.o"). The issue is that the type of .notes section, which contains the BuildID, changed from NOTES to PROGBITS. Ard Biesheuvel figured out that whichever object gets linked first gets to decide the type of a section. The PROGBITS type is the result of the compiler emitting .note.GNU-stack as PROGBITS rather than NOTE. While Ard provided a fix for arm64, I want to fix this globally because the same issue is happening on riscv since commit 2348e6bf4421 ("riscv: remove special treatment for the link order of head.o"). This problem will happen in general for other architectures if they start to drop unneeded entries from scripts/head-object-list.txt. Discard .note.GNU-stack in include/asm-generic/vmlinux.lds.h.

In the case where a firmware file is too large (e.g. someone downloaded a web page ASCII dump from github...), the firmware object is released but the pointer is not zerod. If no other firmware file was found then release would be called again leading to a double kfree. Also, the size check was only being applied to the initial firmware load not any of the subsequent attempts. So move the check into a wrapper that is used for all loads.

2022-12-30drm/i915: improve the catch-all evict to handle lock contentionMatthew Auld6-26/+82
The catch-all evict can fail due to object lock contention, since it only goes as far as trylocking the object, due to us already holding the vm->mutex. Doing a full object lock here can deadlock, since the vm->mutex is always our inner lock. Add another execbuf pass which drops the vm->mutex and then tries to grab the object will the full lock, before then retrying the eviction. This should be good enough for now to fix the immediate regression with userspace seeing -ENOSPC from execbuf due to contended object locks during GTT eviction. v2 (Mani) - Also revamp the docs for the different passes.
