2010-07-27[SCSI] arcmsr: Support 1024 scatter-gather list entries and improve AP while ↵Nick Cheng1-78/+57
FW trapped and behaviors of EHs 1. To support 4M/1024 scatter-gather list entry, reorganize struct ARCMSR_CDB and struct CommandControlBlock 2. To modify arcmsr_probe 3. In order to help fix F/W issue, add the driver mode for type B card 4. To improve AP's behavior while F/W resets 5. To unify struct MessageUnit_B's members' naming in all OS drivers' 6. To improve error handlers, arcmsr_bus_reset(), arcmsr_abort() 7. To fix the arcmsr_queue_command() in bus reset stage, just let the commands pass down to FW, don't block Signed-off-by: Nick Cheng <nick.cheng@areca.com.tw> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
2010-05-25[SCSI] arcmsr: Support HW reset for EH and polling scheme for scsi deviceNick Cheng1-9/+20
1. To support instantaneous report for SCSI device existing by periodic polling 2. In arcmsr_iop_xfer(), inform AP of F/W's deadlock state to prevent endless waiting 3. To block the coming SCSI command while the driver is handling bus reset 4.

2008-03-14[SCSI] arcmsr: fix iounmap error for Type B adapternickcheng1-7/+7
The Type B Adapter teardown does iounmap on pointers subtracted by a constant offset. Since the offset is in bytes, we need the pointers to be of type void * not uint32_t * so the subtraction is done in the correct units and we iounmap the correct area.

2008-02-07[SCSI] arcmsr: updates (1.20.00.15)Nick Cheng1-1/+3
- add arcmsr_enable_eoi_mode()and readl(reg->iop2drv_doorbell_reg) in arcmsr_handle_hbb_isr() on adapter Type B in case of the doorbell interrupt clearance is cached - add conditional declaration for arcmsr_pci_error_detected() and arcmsr_pci_slot_reset - check if the sg list member number exceeds arcmsr default limit in arcmsr_build_ccb() - change the returned value type of arcmsr_build_ccb()from "void" to "int" returns FAILED in arcmsr_queue_command() - modify arcmsr_drain_donequeue() to ignore unknown command and let kernel process command timeout. This could handle IO request violating maximum segments, i.e. Linux XFS over DM-CRYPT. Thanks to Milan Broz's comments <mbroz@redhat.com> - fix the release of dma memory for type B in arcmsr_free_ccb_pool() - fix the arcmsr_polling_hbb_ccbdone() Signed-off-by: Nick Cheng <nick.cheng@areca.com.tw> Cc: Milan Broz <mbroz@redhat.com> Cc: <thenzl@redhat.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
2007-10-29deal with resource allocation bugs in arcmsrAl Viro1-9/+0
a) for type B we should _not_ iounmap() acb->pmu; it's not ioremapped. b) for type B we should iounmap() two regions we _do_ ioremap. c) if ioremap() fails, we need to bail out (and clean up).

2007-06-17[SCSI] areca: improve driver stability and compatibilitynickcheng(鄭守謙1-2/+2
Description: 1. Implement PCI-Express error recovery function and AER capability, especially thanks to Yanmin Zhang's openhanded help about AER 2. Implement the selection of ARCMSR_MAX_XFER_SECTORS_B=4096 if firmware version is latter than 1.42 3. Add arcmsr_done4_abort_postqueue in arcmsr_iop_reset function to improve the stability as hot-unplug/plug 4. Modify the ISR, arcmsr_interrupt routine, to prevent the inconsistency with sg_mod driver if application directly calls the arcmsr driver w/o passing through scsi midlayer Signed-off-by: Nick Cheng <nick.cheng@areca.com.tw> [jejb: unused variable removal] Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
