From df46b9a44ceb5af2ea2351ce8e28ae7bd840b00f Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Mon, 20 Jun 2005 14:04:44 +0200 Subject: [PATCH] Add blk_rq_map_kern() Add blk_rq_map_kern which takes a kernel buffer and maps it into a request and bio. This can be used by the dm hw_handlers, old sg_scsi_ioctl, and one day scsi special requests so all requests comming into scsi will have bios. All requests having bios should allow scsi to use scatter lists for all IO and allow it to use block layer functions.

If you set the bit immediately, you get into the situation where the transport parameters report something as being set even if the drive cannot support it. I patched the driver to do it this way and also corrected a panic in the proc routines.

However, just in case anyone should want to do this, it's appropriate to include the parameter. I don't do anything with it in DV by design, so the parameter will come up as off by default, so if anyone actually wants to play with the margin control settings they'll have to enable it under the spi_transport class first.

This reduced the PCI traffic in the driver to submit a command to the queue to near zero allowing a significant number of commands to be turned around with no need to block for the PCI bridge to flush the notify request to the adapter. Interrupt mitigation has always been present in the driver; it was turned off because of a bug that prevented one from realizing the usefulness of the feature. This bug is fixed in this patch.

Brian King has acknowledged that it fixes the problems he has seen. Seems mature enough for inclusion into 2.6.14 (or later)? Nate's explanation of the changes: I've attached patches against 2.6.13rc2. These are basically identical to my earlier patches, as I found that all issues I'd seen in earlier kernels still existed in this kernel. To summarize, the changes are: (more details in my original email) - add a kref to the scsi_tape structure, and associate reference counting stuff - set sr_request->end_io = blk_end_sync_rq so we get notified when an IO is rejected when the device goes away - check rq_status when IOs complete, else we don't know that IOs rejected for a dead device in fact did not complete - change last_SRpnt so it's set before an async IO is issued (in case st_sleep_done is bypassed) - fix a bogus use of last_SRpnt in st_chk_result Signed-off-by: Nate Dailey Signed-off-by: Kai Makisara Signed-off-by: James Bottomley --- drivers/scsi/st.c | 150 +++++++++++++++++++++++++++++++++++++++++++----------- drivers/scsi/st.h | 3 +- 2 files changed, 123 insertions(+), 30 deletions(-) (limited to 'drivers') diff --git a/drivers/scsi/st.c b/drivers/scsi/st.c index 0291a8fb654d..47a5698a712a 100644 --- a/drivers/scsi/st.c +++ b/drivers/scsi/st.c @@ -17,7 +17,7 @@ Last modified: 18-JAN-1998 Richard Gooch Devfs support */ -static char *verstr = "20050501"; +static char *verstr = "20050802"; #include @@ -219,6 +219,12 @@ static int switch_partition(struct scsi_tape *); static int st_int_ioctl(struct scsi_tape *, unsigned int, unsigned long); +static void scsi_tape_release(struct kref *); + +#define to_scsi_tape(obj) container_of(obj, struct scsi_tape, kref) + +static DECLARE_MUTEX(st_ref_sem); + #include "osst_detect.h" #ifndef SIGS_FROM_OSST @@ -230,6 +236,46 @@ static int st_int_ioctl(struct scsi_tape *, unsigned int, unsigned long); {"OnStream", "FW-", "", "osst"} #endif +static struct scsi_tape *scsi_tape_get(int dev) +{ + struct scsi_tape *STp = NULL; + + down(&st_ref_sem); + write_lock(&st_dev_arr_lock); + + if (dev < st_dev_max && scsi_tapes != NULL) + STp = scsi_tapes[dev]; + if (!STp) goto out; + + kref_get(&STp->kref); + + if (!STp->device) + goto out_put; + + if (scsi_device_get(STp->device)) + goto out_put; + + goto out; + +out_put: + kref_put(&STp->kref, scsi_tape_release); + STp = NULL; +out: + write_unlock(&st_dev_arr_lock); + up(&st_ref_sem); + return STp; +} + +static void scsi_tape_put(struct scsi_tape *STp) +{ + struct scsi_device *sdev = STp->device; + + down(&st_ref_sem); + kref_put(&STp->kref, scsi_tape_release); + scsi_device_put(sdev); + up(&st_ref_sem); +} + struct st_reject_data { char *vendor; char *model; @@ -311,7 +357,7 @@ static int st_chk_result(struct scsi_tape *STp, struct scsi_request * SRpnt) return 0; cmdstatp = &STp->buffer->cmdstat; - st_analyze_sense(STp->buffer->last_SRpnt, cmdstatp); + st_analyze_sense(SRpnt, cmdstatp); if (cmdstatp->have_sense) scode = STp->buffer->cmdstat.sense_hdr.sense_key; @@ -399,10 +445,10 @@ static void st_sleep_done(struct scsi_cmnd * SCpnt) (STp->buffer)->cmdstat.midlevel_result = SCpnt->result; SCpnt->request->rq_status = RQ_SCSI_DONE; - (STp->buffer)->last_SRpnt = SCpnt->sc_request; DEB( STp->write_pending = 0; ) - complete(SCpnt->request->waiting); + if (SCpnt->request->waiting) + complete(SCpnt->request->waiting); } /* Do the scsi command.

This code will apply a global timeout (of the total number of retries times the per command timer) to a given command. If it is exceeded, the command is completed regardless of its state. The patch also removes the unused field in the command: timeout and timeout_total. This solves the problem of detecting an endless loop in the mid-layer because of BUSY/QUEUE_FULL bouncing, but will not recover the device. In the aic7xxx case, the driver can be recovered by sending a bus reset, so possibly this should be tied into the error handler?

It converts scsi_wait_req to do correct REQ_BLOCK_PC submission (and works nicely in my setup). The final goal should be to eliminate struct scsi_request, but that can't be done until the character submission paths of sg and st are also modified. There's some loss of functionality to this: retries are no longer controllable (except by setting REQ_FASTFAIL) and the wait_req API needs to be altered, but it looks very nice.

Try to do this on 2.6.12: - Kill udev and HAL - Insert a CD-ROM into a SCSI or USB CD-ROM drive - Run dd if=/dev/scd0 - cat /sys/block/sr0/size - Eject the CD, insert a different one - Run dd if=/dev/scd0 This is likely to do "access beyond the end of device", if you let it - cat /sys/block/sr0/size This shows the size of a previous CD, even though dd was supposed to revalidate the device. - Run dd if=/dev/scd0 The second run of dd works correctly! The bug was introduced in 2.5.31, when Al fixes the recursive opens in partitioning. Before, the code worked like this: - Block layer called cdrom_open directly - cdrom_open called sr_open - sr_open called check_disk_change - check_disk_change called sr_media_change - sr_media_change did cd->needs_disk_change=1 - before returning sr_open tested cd->needs_disk_change and called get_sector_size. In 2.6.12, the check_disk_change is called from cdrom_open only. Thus: - Block layer calls sr_bd_open - sr_bd_open calls cdrom_open - cdrom_open calls sr_open - sr_open tests cd->needs_disk_change, which wasn't set yet; returns - cdrom_open calls check_disk_change - check_disk_change calls sr_media_change - sr_media_change does cd->needs_disk_change=1, but nobody cares Acked by: Alexander Viro Signed-off-by: James Bottomley --- drivers/scsi/sr.c | 24 ++---------------------- drivers/scsi/sr.h | 1 - 2 files changed, 2 insertions(+), 23 deletions(-) (limited to 'drivers') diff --git a/drivers/scsi/sr.c b/drivers/scsi/sr.c index 2f259f249522..f63d8c6c2a33 100644 --- a/drivers/scsi/sr.c +++ b/drivers/scsi/sr.c @@ -199,15 +199,7 @@ int sr_media_change(struct cdrom_device_info *cdi, int slot) /* check multisession offset etc */ sr_cd_check(cdi); - /* - * If the disk changed, the capacity will now be different, - * so we force a re-read of this information - * Force 2048 for the sector size so that filesystems won't - * be trying to use something that is too small if the disc - * has changed. - */ - cd->needs_sector_size = 1; - cd->device->sector_size = 2048; + get_sectorsize(cd); } return retval; } @@ -538,13 +530,6 @@ static int sr_open(struct cdrom_device_info *cdi, int purpose) if (!scsi_block_when_processing_errors(sdev)) goto error_out; - /* - * If this device did not have media in the drive at boot time, then - * we would have been unable to get the sector size.

The transport class uses REQ_FAILFAST, so another interface (scsi_execute) had to be invented to take the extra flag. Also, the sense functions are shifted around to allow spi_execute to place data directly into a struct scsi_sense_hdr. With this change, there's probably a lot of unnecessary sense buffer allocation going on which we can fix later.

In the process, I noticed we have no callers of scsi_wait_req who don't immediately normalise the sense, so I updated the API to make it take a struct scsi_sense_hdr instead of simply a big sense buffer.

This, unfortunately, leads to potential scheduling while atomic problems if there's a sleep in the function called by a trigger. The correct solution is to use the kernel klist infrastructure instead which allows lockless traversal of a list.

To do that, I've made this class a transport class that's entirely subsystem independent (although the matching routines have to match per subsystem, as you'll see looking at the code). I put it in the scsi subdirectory purely because I needed somewhere to play with it, but it's not a scsi specific module. I used a fusion raid card as the test bed for this; with that kind of card, this is the type of class output you get: jejb@titanic> ls -l /sys/class/raid_devices/20\:0\:0\:0/ total 0 lrwxrwxrwx 1 root root 0 Aug 16 17:21 component-0 -> ../../../devices/pci0000:80/0000:80:04.0/host20/target20:1:0/20:1:0:0/ lrwxrwxrwx 1 root root 0 Aug 16 17:21 component-1 -> ../../../devices/pci0000:80/0000:80:04.0/host20/target20:1:1/20:1:1:0/ lrwxrwxrwx 1 root root 0 Aug 16 17:21 device -> ../../../devices/pci0000:80/0000:80:04.0/host20/target20:0:0/20:0:0:0/ -r--r--r-- 1 root root 16384 Aug 16 17:21 level -r--r--r-- 1 root root 16384 Aug 16 17:21 resync -r--r--r-- 1 root root 16384 Aug 16 17:21 state So it's really simple: for a SCSI device representing a hardware raid, it shows the raid level, the array state, the resync % complete (if the state is resyncing) and the underlying components of the RAID (these are exposed in fusion on the virtual channel 1). As you can see, this type of information can be exported by almost anything, including software raid. The more difficult trick, of course, is going to be getting it to perform configuration type actions with writable attributes.

This patch removes the redundant NULL checks and also a few similar checks for NULL before calls to kfree() that I ran into while doing the crypto_free_tfm bits. I've succesfuly compile tested this patch, and a kernel with the patch applied boots and runs just fine. When I posted the patch to LKML (and other lists/people on Cc) it drew the following comments : J. Bruce Fields commented "I've no problem with the auth_gss or nfsv4 bits.--b." Sridhar Samudrala said "sctp change looks fine." Herbert Xu signed off on the patch. So, I guess this is ready to be dropped into -mm and eventually mainline.

Since all watchdog drivers use the misc_register() call, they will end up in /sys/class/misc/$foo. udev may create the /dev/watchdog node if the driver is loaded. I dont have such a device, so I cant test it. The drivers below provide names with spaces and even with / in it. Not a big deal, but apps may expect /dev/watchdog.

Load the module without the nowayout option. 2. Open the driver and close it without writing 'V' before close. 3. Unload the module. The timer will continue to run... 4. Oops happens when timer fires. Reported Sun, 10 Oct 2004, by Michael Schierl Fix is easy: always take a reference on the module on open. Release it only when the device is closed and no timer is running. Tested on 2.6.13-rc6 using the soft_noboot option. While the timer is running and the device is closed, the module use count stays at 1. After the timer fires, it drops to 0. Repeatedly opening and closing the driver caused no problems. Please apply.

The timer has implementation dependent timeout frequencies that can be configured by software. One the first Watchdog timeout we get a critical exception. It is left to board specific code to determine what should happen at this point. If nothing is done and another timeout period expires the processor may attempt to reset the machine. Command line parameters: wdt=0 : disable watchdog (default) wdt=1 : enable watchdog wdt_period=N : N sets the value of the Watchdog Timer Period. The Watchdog Timer Period meaning is implementation specific. Check User Manual for the processor for more details. This patch is based off of work done by Takeharu Kato.
