2021-02-08scsi: qla4xxx: Use iscsi_is_session_online()Mike Christie
__qla4xxx_is_chap_active() just wants to know if a session is online and does not care about why it's not, so this has it use iscsi_is_session_online(). This is not a bug now, but the next patch changes the behavior of iscsi_session_chkready() so this patch just prepares the driver for that change.

2020-12-01scsi: qla4xxx: Remove in_interrupt() from qla4_82xx_rom_lock()Ahmed S. Darwish
qla4_82xx_rom_lock() spins on a certain hardware state until it is updated. At the end of each spin, if in_interrupt() is true, it does 20 loops of cpu_relax(). Otherwise, it yields the CPU. While in_interrupt() is ill-defined and does not provide what the name suggests, it is not needed here: qla4_82xx_rom_lock() is always called from process context. Below is an analysis of its callers: - ql4_nx.c: qla4_82xx_rom_fast_read(), all process context callers: => ql4_nx.c: qla4_82xx_pinit_from_rom(), GFP_KERNEL allocation => ql4_nx.c: qla4_82xx_load_from_flash(), msleep() in a loop - ql4_nx.c: qla4_82xx_pinit_from_rom(), earlier discussed - ql4_nx.c: qla4_82xx_rom_lock_recovery(), bound to "isp_operations" ->rom_lock_recovery() hook, which has one process context caller, qla4_8xxx_device_bootstrap(), with callers: => ql4_83xx.c: qla4_83xx_need_reset_handler(), process, msleep() => ql4_nx.c: qla4_8xxx_device_state_handler(), multiple msleep()s - ql4_nx.c: qla4_82xx_read_flash_data(), has cond_resched() Remove the in_interrupt() check. Mark, qla4_82xx_rom_lock(), and the ->rom_lock_recovery() hook, with "Context: task, can sleep". Change qla4_82xx_rom_lock() implementation to sleep 20ms, instead of a schedule(), for each spin. This is more deterministic, and it matches the other implementations bound to ->rom_lock_recovery().

2020-12-01scsi: qla4xxx: Remove in_interrupt() from qla4_82xx_idc_lock()Ahmed S. Darwish
qla4_82xx_idc_lock() spins on a certain hardware state until it is updated. At the end of each spin, if in_interrupt() is true, it does 20 loops of cpu_relax(). Otherwise, it yields the CPU. While in_interrupt() is ill-defined and does not provide what the name suggests, it is not needed here: qla4_82xx_idc_lock() is always called from process context. Below is an analysis of its callers: - ql4_nx.c: qla4_82xx_need_reset_handler(), 1-second msleep() in a loop. - ql4_nx.c: qla4_82xx_isp_reset(), calls qla4_8xxx_device_state_handler(), which has multiple msleep()s. Beside direct calls, qla4_82xx_idc_lock() is also bound to isp_operations ->idc_lock() hook. Other functions which are bound to the same hook, e.g. qla4_83xx_drv_lock(), also have an msleep(). For completeness, below is an analysis of all callers of that hook: - ql4_83xx.c: qla4_83xx_need_reset_handler(), has an msleep() - ql4_83xx.c: qla4_83xx_isp_reset(), calls qla4_8xxx_device_state_handler(), which has multiple msleep()s. - ql4_83xx.c: qla4_83xx_disable_pause(), all process context callers: => ql4_mbx.c: qla4xxx_mailbox_command(), msleep(), mutex_lock() => ql4_os.c: qla4xxx_recover_adapter(), schedule_timeout() in loop => ql4_os.c: qla4xxx_do_dpc(), workqueue context - ql4_attr.c: qla4_8xxx_sysfs_write_fw_dump(), sysfs bin_attribute ->write() hook, process context - ql4_mbx.c: qla4xxx_mailbox_command(), earlier discussed - ql4_nx.c: qla4_8xxx_device_bootstrap(), callers: => ql4_83xx.c: qla4_83xx_need_reset_handler(), process, msleep() => ql4_nx.c: qla4_8xxx_device_state_handler(), earlier discussed - ql4_nx.c: qla4_8xxx_need_qsnt_handler(), callers: => ql4_nx.c: qla4_8xxx_device_state_handler(), multiple msleep()s => ql4_os.c: qla4xxx_do_dpc(), workqueue context - ql4_nx.c: qla4_8xxx_update_idc_reg(), callers: => ql4_nx.c: qla4_8xxx_device_state_handler(), earlier discussed => ql4_os.c: qla4_8xxx_error_recovery(), only called by qla4xxx_pci_slot_reset(), which is bound to PCI ->slot_reset() process-context hook - ql4_nx.c: qla4_8xxx_device_state_handler(), earlier discussed - ql4_os.c: qla4xxx_recover_adapter(), earlier discussed - ql4_os.c: qla4xxx_do_dpc(), earlier discussed Remove the in_interrupt() check. Mark, qla4_82xx_idc_lock(), and the ->idc_lock() hook itself, with "Context: task, can sleep". Change qla4_82xx_idc_lock() implementation to sleep 100ms, instead of a schedule(), for each spin. This is more deterministic, and it matches other PCI HW locking functions in the driver.

2020-12-01scsi: qla4xxx: Remove in_interrupt()Ahmed S. Darwish
qla4_82xx_crb_win_lock() spins on a certain hardware state until it's updated. At the end of each spin, if in_interrupt() is true, it does 20 loops of cpu_relax(). Otherwise, it yields the CPU. The in_interrupt() macro is ill-defined as it does not provide what the name suggests, and it does not catch the intended use-case here. qla4_82xx_crb_win_lock() is always invoked with scsi_qla_host::hw_lock acquired, with disabled interrupts. If the caller is in process context, as in qla4_82xx_need_reset_handler(), then in_interrupt() will return false even though it is not allowed to call schedule(). Remove the in_interrupt() check. Change qla4_82xx_crb_win_lock() specification to a purely atomic function. Mark it as static, remove its forward declaration, and move it above its callers. To avoid hammering the PCI bus while spinning, use a 10 micro-second delay instead of cpu_relax().

The driver is currently using an odd mix of legacy PCI DMA API and generic DMA API calls, switch it over to the generic API entirely. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Johannes Thumshirn <jthumshirn@suse.de> Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>
2018-10-02PCI/AER: Remove pci_cleanup_aer_uncorrect_error_status() callsOza Pawandeep
After bfcb79fca19d ("PCI/ERR: Run error recovery callbacks for all affected devices"), AER errors are always cleared by the PCI core and drivers don't need to do it themselves. Remove calls to pci_cleanup_aer_uncorrect_error_status() from device driver error recovery functions.
