2005-12-16[SCSI] Merge sym53c8xx_comm.h and sym53c8xx_defs.h into ncr driverMatthew Wilcox
When the sym1 driver was in the tree, it used to share various parts of its infrastructure with the ncr driver. Now it's gone, these files are just an annoyance, so merge sym53c8xx_comm.h into ncr53c8xx.c and merge sym53c8xx_defs.h into ncr53c8xx.h.

2005-12-16[SCSI] Use spi_print_msg in ncr53c8xx driverMatthew Wilcox
The ncr53c8xx driver had its own loop to print scsi messages. Use the SPI one instead. Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-12-16[SCSI] 53c700: update endian processing macrosJames Bottomley
This update now allows this driver to be used on big endian bus machines that aren't parisc. To do that, the driver must set a CONFIG_53C700_BE_BUS in Kconfig to compile the right macro versions. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-12-15[SCSI] Add PPR support to spi_print_msgMatthew Wilcox
Introduce a new helper, print_nego() to handle SDTR/WDTR/PPR. Split out the guts of show_spi_transport_period_helper() into period_to_str() and use it in print_nego to get the period factor conversion right.

2005-12-15[SCSI] Rename scsi_print_msg to spi_print_msgMatthew Wilcox

2005-12-15[SCSI] Move scsi_print_msg to SPI classMatthew Wilcox
scsi_print_msg() is an SPI-specific concept. This patch moves it from constants.c to scsi_transport_spi.c and updates the Kconfig to link in the SPI class for the drivers which use scsi_print_msg().

2005-12-15Merge by hand (conflicts in scsi_lib.c)James Bottomley
This merge is pretty extensive. The conflict is over the new req->retries parameter, so I had to change the prototype to scsi_setup_blk_pc_cmnd() and the usage in sd, sr and st. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-12-15[SCSI] Fix st oops with new scsi_execute infrastructureKai Makisara
Patch from Kai minus last sg_segs clearing which was merged already. > > Was there a oops or lockup or any debug output you can send me? I will try > > some more large request tests with scsi_debug. You also have to compile your > > kernel with SCSI_MAX_PHYS_SEGMENTS == 255 to get larger requests now. > It was an oops in sgl_unmap_user_pages(). The reason is this: /* XXX: just for debug. Remove when PageReserved is removed */ BUG_ON(PageReserved(page)); I was using /dev/zero as input and it triggers this. When I used a file as input, this did not trigger. Should this BUG_ON be removed? In the same log I noticed that there was another ->sg_segs inconsistency. Also, the field ->last_SRpnt was not reset when scsi_execute_async() failed. This caused the error message "Async command already active" later and prevented proper close. While doing the changes, I noticed that the current code (since 2.6.0-test4) does not set the pages dirty when reading with direct i/o. All of these st problems (including the one I sent earlier) are fixed in the patch at the end of this message. These fixes should probably be included already in 2.6.15. After these fixes, the tape seems to operate as expected. Without other changes, the largest block size with sym53c896 SCSI adapter is 384 kB. The maximum number of sg segments is set to 96 and clustering is disabled in the driver. 96 x 4 kB = 384 kB. OK. I enabled clustering and set max_sectors to 10000 in the SCSI HBA driver. Now the block size limit is 5000 kB as expected. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-12-15[SCSI] seperate max_sectors from max_hw_sectorsMike Christie
- export __blk_put_request and blk_execute_rq_nowait needed for async REQ_BLOCK_PC requests - seperate max_hw_sectors and max_sectors for block/scsi_ioctl.c and SG_IO bio.c helpers per Jens's last comments. Since block/scsi_ioctl.c SG_IO was already testing against max_sectors and SCSI-ml was setting max_sectors and max_hw_sectors to the same value this does not change any scsi SG_IO behavior. It only prepares ll_rw_blk.c, scsi_ioctl.c and bio.c for when SCSI-ml begins to set a valid max_hw_sectors for all LLDs. Today if a LLD does not set it SCSI-ml sets it to a safe default and some LLDs set it to a artificial low value to overcome memory and feedback issues. Note: Since we now cap max_sectors to BLK_DEF_MAX_SECTORS, which is 1024, drivers that used to call blk_queue_max_sectors with a large value of max_sectors will now see the fs requests capped to BLK_DEF_MAX_SECTORS.

2005-12-15[PATCH] Au1550 AC'97 OSS driver spinlock fixesSergei Shtylylov
We have found some issues with Au1550 AC'97 OSS driver in 2.6 (sound/oss/au1550_ac97.c), though it also should concern 2.4 driver (drivers/sound/au1550_psc.c). start_dac() grabs a spinlock already held by its caller, au1550_write(). This doesn't show up with the standard UP spinlock impelmentation but when the different one (mutex based) is in use, a lockup happens. And the interrupt handlers also didn't grab the spinlock -- that's OK in the usual kernel but not when the IRQ handlers are threaded. So, they're grabbing the spinlock now (as every correct interrupt handler should do).

2005-12-15[PATCH] IPMI oops fixPaolo Galtieri
While doing some testing I discovered that if the BIOS on a board does not properly setup the DMI information it leads to a panic in the IPMI code. The panic is due to dereferencing a pointer which is not initialized. The pointer is initialized in port_setup() and/or mem_setup() and used in init_one_smi() and cleanup_one_si(), however if either port_setup() or mem_setup() return ENODEV the pointer does not get initialized.

2005-12-14[SCSI] convert st to use scsi_execute_asyncMike Christie
convert st to always send scatterlists and kill scsi_request usage. This is the same as last time as it was posted, but with Kai's patches merged and we now pass the bytes value to scsi_execute_async. TODO: - move DIO code to common place or make block layers usable for ULDs. - move buffer allocation code to common place for all ULDs to use. And make buffer allocation code handle all queue limits so we can find out about problems before calling scsi_execute_async. - move indirect (copy_to/from_user) paths commone place or make block layers usable for ULDs.

2005-12-14[SCSI] convert sg to scsi_execute_asyncMike Christie
Convert sg to always send scatterlists, and kill scsi_request usage. TODO: - move DIO code to common place or make block layers usable for ULDs. - move buffer allocation code to common place for all ULDs to use. And make buffer allocation code obey all queue limits so we can find out about problems before calling scsi_execute_async. Currently, sg.c could allocate a buffer that is too large, and send the request to scsi_execute_async. scsi_execute_async will then check it against all the queue limits and return a failure in this case. It would nicer to know about the queue limit violation right away. - move indirect (copy_to/from_user) paths commone place or make block layers usable for ULDs.

2005-12-14[SCSI] add kmemcache for scsi_io_contextMike Christie
Add kmemcache of scsi io contexts. In the future when we finalize on where these functions will live we can add a mempool for it and do a bioset for out REQ_BLOCK_PC bios. This is needed becuase the dm-multipath handlers will want to use the scsi_exectute* functions for failover and we cannot have them and the bio device allocating from the same mempool.

2005-12-14[SCSI] complete the whole command when it is REQ_BLOCK_PCMike Christie
sd does not allow scsi_io_completion to retry commands for SG_IO requests, and it make sense that it should not happen for st SG_IO commands too. If for st we hit the bottom of scsi_io_completion we will probably screw things up pretty bad. This patch returns to the block layer that the whole command completed and relies on the caller to check the request errors field. For initialization commands like in sd, this adds the previous behavior where scsi_io_completion did not process the error.

2005-12-14[SCSI] add retries field to request for REQ_BLOCK_PC useMike Christie
For tape we need to control the retries. This patch adds a retries counter on the request for REQ_BLOCK_PC commands originating from scsi_execute* to use. REQ_BLOCK_PC commands comming from the block layer SG_IO path continue to use the retires set in the ULD init_command. (scsi_execute* does not set the gendisk so we do not execute the init_command in that path).
