* scsi: ata: Use unsigned int for cmd's type in ioctls in scsi_host_templateNathan Chancellor2019-02-081-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Clang warns several times in the scsi subsystem (trimmed for brevity): drivers/scsi/hpsa.c:6209:7: warning: overflow converting case value to switch condition type (2147762695 to 18446744071562347015) [-Wswitch] case CCISS_GETBUSTYPES: ^ drivers/scsi/hpsa.c:6208:7: warning: overflow converting case value to switch condition type (2147762694 to 18446744071562347014) [-Wswitch] case CCISS_GETHEARTBEAT: ^ The root cause is that the _IOC macro can generate really large numbers, which don't fit into type 'int', which is used for the cmd parameter in the ioctls in scsi_host_template. My research into how GCC and Clang are handling this at a low level didn't prove fruitful. However, looking at the rest of the kernel tree, all ioctls use an 'unsigned int' for the cmd parameter, which will fit all of the _IOC values in the scsi/ata subsystems. Make that change because none of the ioctls expect a negative value for any command, it brings the ioctls inline with the reset of the kernel, and it removes ambiguity, which is never good when dealing with compilers.

* | scsi: aacraid: Perform initialization reset only onceGuilherme G. Piccoli2017-11-211-0/+1
|/ | | | | | | | | | | | | | | | | | | | | Currently the driver accepts two ways of requesting an initialization reset on the adapter: by passing aac_reset_devices module parameter, or the generic kernel parameter reset_devices. It's working as intended...but if we end up reaching a scsi hang and the scsi EH mechanism takes place, aacraid performs resets as part of the scsi error recovery procedure. These EH routines might reinitialize the device, and if we have provided some of the reset parameters in the kernel command-line, we again perform an "initialization" reset. So, to avoid this duplication of resets in case of scsi EH path, this patch adds a field to aac_dev struct to keep per-adapter track of the init reset request - once it's done, we set it to false and don't proactively reset anymore in case of reinitializations.

* scsi: aacraid: Save adapter fib log before an IOP resetRaghava Aditya Renukunta2017-02-231-0/+6
| | | | | | | | | | | | | | Currently the adapter firmware does not save outstanding I/O's log information when an IOP reset is triggered. This is problematic when trying to root cause and debug issues. Fixed by adding sync command to trigger I/O log file save in the adapter firmware before issuing an IOP reset.

| | | | | | | | | | | | | | After controller shutdown, all sync fibs time out due to not knowing about the switch to INT-x mode Fixed by replacing aac_src_access_devreg() to aac_set_intx_mode() call.
