* scsi: qla4xxx: Convert uses of __constant_cpu_to_<foo> to cpu_to_<foo>Dwaipayan Ray2021-08-011-5/+5
| | | | | | | | | | | | | | | | | | | | The macros cpu_to_le16() and cpu_to_le32() have special cases for constants. Their __constant_<foo> versions are not required. On little endian systems, both cpu_to_le16() and __constant_cpu_to_le16() expand to the same expression. Same is the case with cpu_to_le32(). On big endian systems, cpu_to_le16() expands to __swab16() which has a __builtin_constant_p check. Similarly, cpu_to_le32() expands to __swab32(). Consequently these macros can be safely used with constants, and hence all those uses are converted. This was discovered as a part of a checkpatch evaluation, looking at all reports of WARNING:CONSTANT_CONVERSION error type.

* scsi: qla4xxx: Remove in_interrupt() from qla4_82xx_rom_lock()Ahmed S. Darwish2020-12-011-10/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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().

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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().

This patch replaces cases of: kmalloc(a * b, gfp) with: kmalloc_array(a * b, gfp) as well as handling cases of: kmalloc(a * b * c, gfp) with: kmalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kmalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kmalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The tools/ directory was manually excluded, since it has its own implementation of kmalloc().

| | | | | | | | | | | | | | | | | | | | | | | | Issue: Driver holds rom-lock for too long during reset recovery. During adapter reset testing, it was found that the driver holds the rom-lock for too long, because of which other drivers fail to acquire the rom-lock, leading to reset failures. The primary cause is, in the bootstrap code, while holding the rom-lock, the driver checks if the peg is halted, causing a 2 second contention. Fix: When a reset recovery starts, the driver deduces the cause, and sets appropriate flags in watchdog & recover_adapter routines. This flag should be used to determine if bootstrap is invoked from probe or reset context, reducing the rom-lock footprint of the drivers.

FW generates AEN and at same time driver enables Mailbox Interrupt 3. Driver issues new mailbox to Firmware In above case driver will not get AEN interrupts generated by FW in step #2 as FW generated this AEN when interrupts are disabled. During the same time driver enabled the mailbox interrupt, so driver will not poll for interrupt. Driver will never process AENs generated in step #2 and issues new mailbox to FW, but now FW is not able to post mailbox completion as AENs generated before are not processed by driver. Fix: Enable Mailbox / AEN interrupts before initializing FW in case of ISP83XX. This will make sure we process all Mailbox and AENs in interrupt mode.
