2008-04-29[SCSI] megaraid_mbox: fix Dell CERC firmware problemHannes Reinecke1-0/+1
Newer Dell CERC firmware (>= 6.62) implement a random deletion handling compatible with the legacy megaraid driver. The legacy handling shifted the target ID by 0x80 only for I/O commands (READ/WRITE/etc), whereas megaraid_mbox shifts the target ID always if random deletion is supported. The resulted in megaraid_mbox sending an INQUIRY to the wrong channel, and not finding any devices, obviously. So we disable the random deletion support if the offending firmware is found.

2007-07-14[SCSI] megaraid_mbox: use mutex instead of semaphoreMatthias Kaehlcke1-2/+2
The Megaraid Mailbox driver uses a semaphore as mutex. Use the mutex API instead of the (binary) semaphore.

kernel-doc modifications: - change "@param var" notation to @var; - change function/description separator from ':' to '-'; - change var/description separator from '-' to ':'; - fix a few doc. typos; - don't use kernel-doc /** lead-in when the doc. block is not kernel-doc; - use Linux common */ ending comment format instead of **/; - use correct function parameter names; - place function parameters immediately after the function short description; - place kernel-doc immediately before its function or macro; Signed-off-by: Randy Dunlap <randy.dunlap@oracle.com> Acked-by: Sumant Patro <sumantp@lsil.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2007-01-13[SCSI] megaraid_{mm,mbox}: init fix for kdumpSumant Patro1-2/+2
1. Changes in Initialization to fix kdump failure. Send SYNC command on loading. This command clears the pending commands in the adapter and re-initialize its internal RAID structure. Without this change, megaraid driver either panics or fails to initialize the adapter during kdump's second kernel boot if there are pending commands or interrupts from other devices sharing the same IRQ. 2. Authors email-id domain name changed from lsil.com to lsi.com. Also modified the MODULE_AUTHOR to megaraidlinux@lsi.com Signed-off-by: Sumant Patro <sumant.patro@lsi.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2006-07-28[SCSI] megaraid_{mm,mbox}: 64-bit DMA capability checkerJu, Seokmann1-2/+2
This patch contains - a fix for 64-bit DMA capability check in megaraid_{mm,mbox} driver. - includes changes (going back to 32-bit DMA mask if 64-bit DMA mask failes) suggested by James with previous patch. - addition of SATA 150-4/6 as commented by Vasily Averin. With patch, the driver access PCIconfiguration space with dedicated offset to read a signature. If the signature read, it means that the controller has capability to handle 64-bit DMA. Without this patch, the driver used to blindly claim 64-bit DMA capability. The issue has been reported by Vasily Averin [vvs@sw.ru]. Thank you Vasily for the reporting.

2006-04-27[SCSI] megaraid_{mm,mbox}: fix a bug in reset handlerJu, Seokmann1-2/+5
When abort failed, the driver gets reset handleer called. In the reset handler, driver calls 'scsi_done()' callback for same SCSI command packet (struct scsi_cmnd) multiple times if there are multiple SCSI command packet in the pend_list. More over, if there are entry in the pend_lsit with IOCTL packet associated, the driver returns it to wrong free_list so that, in turn, the driver could end up with 'NULL pointer dereference..' during I/O command building with incorrect resource. Also, the patch contains several minor/cosmetic changes besides this.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
