Adding two Ioctl's to scsipi's cd.c to abstract SCSI MMC devices. The ioctl's and their structures are currenly hidden from inclusion for normal userland applications to allow the MMC abstraction interface to mature first. Its useage is mainly for applications dedicated to handling and processing SCSI MMC compliant devices and their media. Examples of these are CDs, DVDs and comparable optical devices but also some magnetic swapable devices that present themselves as a SCSI MMC compliant device. Its current use is currently the to be committed in-kernel UDF filingsystem and its userland tools.

Part 1 of a cleanup pass over the SCSI subsystem. The aim is to name everything "scsi_*", since we really are talking about the SCSI command set, ATAPI transport not withstanding. Improve the names of many structures, and prepend "SCSI_" onto all SCSI command opcodes. Place items described by the SCSI Primary Commands document into scsi_spc.h.

Merge scsipi branch in the mainline. This add support for ATAPI devices (currently only CD-ROM drives on i386). The sys/dev/scsipi system provides 2 busses to which devices can attach (scsibus and atapibus). This needed to change some include files and structure names in the low level scsi drivers.

Set PQUIRK_ONLYBIG in the wdc-atapi frontend, obviating the need to ever test the "bus type" for this. Merge all the code in the SCSI and ATAPI backends for "cd" devices. All of the mode page handling and whatnot is general to SCSI MMC devices, and should never have been separated to begin with. This fixes a variety of problems, and adds load/unload support for SCSI-attached devices.

Make the xxstart() functions reentrant again, as some drivers HBA can call scsipi_done() from their scsipi_request(). For this, add a struct scsipi_xfer * argument to scsipi_command(). If not NULL scsipi_command() will use this to enqueue this xfer, otherwise it'll try to allocate a new one. This scsipi_xfer has to be allocated and initialised by scsipi_make_xs() or equivalent. In xxstart(), allocate a scsipi_xfer using scsipi_make_xs(), and if not NULL, dequeue the buffer before calling scsipi_command(). This makes sure that scsipi_command() will not fail, and also makes sure that xxstart() won't be called again between the BUFQ_PEEK() and BUFQ_GET(). Fix "dequeued wrong buf" panics reported by Juergen Hannken-Illjes in private mail and Andreas Wrede on current-users@. Thanks to Jason Thorpe and Chuck Silver for review, and Andreas Wrede for testing the patch.

add support for an ATAPI attachment for 'sd'. fix 'cd' driver's NCD_SCSI bogosity (was using testing wrong macro!) clean up in various ways: * make common atapi_mode_{sense,select}() functions. * put ATAPI data structures in more sensible headers, split up by device type. * include headers a bit more carefully. * pass flags to attachment-specific cd functions, and use them. * get rid of SCSI bits in scsipi_base.h's scsipi_make_xs(), move them into the correct place in scsi_base.c. * fix minor typo in struct name in scsipiconf.h (which was apparently never used except in a #define later in the same file). * use __attribute__ to force 4-byte alignment for xs command store, so that architectures trying to bus_space_write_multi_N() (where N > 1) that data to a controller won't lose. * clean up a few comments in typos, and make a few #defines easier to understand/maintain. * rename cd_link.h to cdvar.h (via repository copy). This is exactly what a 'var' file is supposed to be.

static void cdstart(struct scsipi_periph *);
Improve handling of memory shortage, to fix problems like: sd3(mpt0:0:1:0): unable to allocate scsipi_xfer sd3: not queued, error 12 Havard Eidnes's analysis of this problem is that the scsipi_xfer pool is competing for resources with other pools, including the the inode and vnode pools which can grow quite large. *_scsipi_cmd(): don't biodone the buffer if scsipi_make_xs() fails, let the caller deal with the problem start function of block devices drivers: dequeue the buffer after the scsipi_command() call. If scsipi_command() fails with ENOMEM don't dequeue the buffer, and schedule a callout to call the start function after some delay. scsipi_init(): prime the scsipi_xfer_pool with one page. This ensure that there is always some scsipi_xfer to play with. If scsipi_command() fails because of pool_get(), we're sure there will be resources available later, when the pending commands have completed. Reviewed by Jason Thorpe and Havard Eidnes. Todo: remove the "unable to allocate scsipi_xfer" and "not queued, error %d" printfs, but I choose to keep them for now, to help make sure the code does what it should.

Merge the gehenna-devsw branch into the trunk. This merge changes the device switch tables from static array to dynamically generated by config(8). - All device switches is defined as a constant structure in device drivers. - The new grammer ``device-major'' is introduced to ``files''. device-major <prefix> char <num> [block <num>] [<rules>] - All device major numbers must be listed up in port dependent majors.<arch> by using this grammer. - Added the new naming convention. The name of the device switch must be <prefix>_[bc]devsw for auto-generation of device switch tables. - The backward compatibility of loading block/character device switch by LKM framework is broken. This is necessary to convert from block/character device major to device name in runtime and vice versa. - The restriction to assign device major by LKM is completely removed. We don't need to reserve LKM entries for dynamic loading of device switch. - In compile time, device major numbers list is packed into the kernel and the LKM framework will refer it to assign device major number dynamically.

If scsipi_command() fails with ENOMEM don't dequeue the buffer, and schedule a callout to call the start function after some delay. scsipi_init(): prime the scsipi_xfer_pool with one page. This ensure that there is always some scsipi_xfer to play with. If scsipi_command() fails because of pool_get(), we're sure there will be resources available later, when the pending commands have completed. Reviewed by Jason Thorpe and Havard Eidnes. Todo: remove the "unable to allocate scsipi_xfer" and "not queued, error %d" printfs, but I choose to keep them for now, to help make sure the code does what it should.

Overview of changes & features: - All xfers are queued in the mid-layer, rather than doing so in an ad-hoc fashion in individual adapter drivers. - Adapter/channel resource management in the mid-layer, avoids even trying to start running an xfer if the adapter/channel doesn't have the resources. - Better communication between the mid-layer and the adapters. - Asynchronous event notification mechanism from adapter to mid-layer and peripherals. - Better peripheral queue management: freeze/thaw, sorted requeueing during recovery, etc. - Clean separation of peripherals, adapters, and adapter channels (no more scsipi_link). - Kernel thread for each scsipi_channel makes error recovery much easier (no more dealing with interrupt context when recovering from an error). - Mid-layer support for tagged queueing: commands can have the tag type set explicitly, tag IDs are allocated in the mid-layer (thus eliminating the need to use buggy tag ID allocation schemes in many adapter drivers). - support for QUEUE FULL and CHECK CONDITION status in mid-layer; the command will be requeued, or a REQUEST SENSE will be sent as appropriate.

New generic disk framework. Highlights: - New metrics handling. Metrics are now kept in the new `struct disk'. Busy time is now stored as a timeval, and transfer count in bytes. - Storage for disklabels is now dynamically allocated, so that the size of the disk structure is not machine-dependent. - Several new functions for attaching and detaching disks, and handling metrics calculation. Old-style instrumentation is still supported in drivers that did it before. However, old-style instrumentation is being deprecated, and will go away once the userland utilities are updated for the new framework. For usage and architectural details, see the forthcoming disk(9) manual page.

Make the xxstart() functions reentrant again, as some drivers HBA can call scsipi_done() from their scsipi_request(). For this, add a struct scsipi_xfer * argument to scsipi_command(). If not NULL scsipi_command() will use this to enqueue this xfer, otherwise it'll try to allocate a new one. This scsipi_xfer has to be allocated and initialised by scsipi_make_xs() or equivalent. In xxstart(), allocate a scsipi_xfer using scsipi_make_xs(), and if not NULL, dequeue the buffer before calling scsipi_command(). This makes sure that scsipi_command() will not fail, and also makes sure that xxstart() won't be called again between the BUFQ_PEEK() and BUFQ_GET(). Fix "dequeued wrong buf" panics reported by Juergen Hannken-Illjes in private mail and Andreas Wrede on current-users@.

Pull up the thorpej_scsipi branch to main branch. This is a completely rewritten scsipi_xfer execution engine, and the associated changes to HBA drivers. Overview of changes & features: - All xfers are queued in the mid-layer, rather than doing so in an ad-hoc fashion in individual adapter drivers. - Adapter/channel resource management in the mid-layer, avoids even trying to start running an xfer if the adapter/channel doesn't have the resources. - Better communication between the mid-layer and the adapters. - Asynchronous event notification mechanism from adapter to mid-layer and peripherals. - Better peripheral queue management: freeze/thaw, sorted requeueing during recovery, etc. - Clean separation of peripherals, adapters, and adapter channels (no more scsipi_link). - Kernel thread for each scsipi_channel makes error recovery much easier (no more dealing with interrupt context when recovering from an error). - Mid-layer support for tagged queueing: commands can have the tag type set explicitly, tag IDs are allocated in the mid-layer (thus eliminating the need to use buggy tag ID allocation schemes in many adapter drivers). - support for QUEUE FULL and CHECK CONDITION status in mid-layer; the command will be requeued, or a REQUEST SENSE will be sent as appropriate.

New SCSI system, based on Julian's more recent work.
1994-03-29 08:29:20 +04:00
New generic disk framework. Highlights: - New metrics handling. Metrics are now kept in the new `struct disk'. Busy time is now stored as a timeval, and transfer count in bytes. - Storage for disklabels is now dynamically allocated, so that the size of the disk structure is not machine-dependent. - Several new functions for attaching and detaching disks, and handling metrics calculation. Old-style instrumentation is still supported in drivers that did it before. However, old-style instrumentation is being deprecated, and will go away once the userland utilities are updated for the new framework. For usage and architectural details, see the forthcoming disk(9) manual page.

Overview of changes & features: - All xfers are queued in the mid-layer, rather than doing so in an ad-hoc fashion in individual adapter drivers. - Adapter/channel resource management in the mid-layer, avoids even trying to start running an xfer if the adapter/channel doesn't have the resources. - Better communication between the mid-layer and the adapters. - Asynchronous event notification mechanism from adapter to mid-layer and peripherals. - Better peripheral queue management: freeze/thaw, sorted requeueing during recovery, etc. - Clean separation of peripherals, adapters, and adapter channels (no more scsipi_link). - Kernel thread for each scsipi_channel makes error recovery much easier (no more dealing with interrupt context when recovering from an error). - Mid-layer support for tagged queueing: commands can have the tag type set explicitly, tag IDs are allocated in the mid-layer (thus eliminating the need to use buggy tag ID allocation schemes in many adapter drivers). - support for QUEUE FULL and CHECK CONDITION status in mid-layer; the command will be requeued, or a REQUEST SENSE will be sent as appropriate.

Make the xxstart() functions reentrant again, as some drivers HBA can call scsipi_done() from their scsipi_request(). For this, add a struct scsipi_xfer * argument to scsipi_command(). If not NULL scsipi_command() will use this to enqueue this xfer, otherwise it'll try to allocate a new one. This scsipi_xfer has to be allocated and initialised by scsipi_make_xs() or equivalent. In xxstart(), allocate a scsipi_xfer using scsipi_make_xs(), and if not NULL, dequeue the buffer before calling scsipi_command(). This makes sure that scsipi_command() will not fail, and also makes sure that xxstart() won't be called again between the BUFQ_PEEK() and BUFQ_GET(). Fix "dequeued wrong buf" panics reported by Juergen Hannken-Illjes in private mail and Andreas Wrede on current-users@.

Pull up the thorpej_scsipi branch to main branch. This is a completely rewritten scsipi_xfer execution engine, and the associated changes to HBA drivers. Overview of changes & features: - All xfers are queued in the mid-layer, rather than doing so in an ad-hoc fashion in individual adapter drivers. - Adapter/channel resource management in the mid-layer, avoids even trying to start running an xfer if the adapter/channel doesn't have the resources. - Better communication between the mid-layer and the adapters. - Asynchronous event notification mechanism from adapter to mid-layer and peripherals. - Better peripheral queue management: freeze/thaw, sorted requeueing during recovery, etc. - Clean separation of peripherals, adapters, and adapter channels (no more scsipi_link). - Kernel thread for each scsipi_channel makes error recovery much easier (no more dealing with interrupt context when recovering from an error). - Mid-layer support for tagged queueing: commands can have the tag type set explicitly, tag IDs are allocated in the mid-layer (thus eliminating the need to use buggy tag ID allocation schemes in many adapter drivers). - support for QUEUE FULL and CHECK CONDITION status in mid-layer; the command will be requeued, or a REQUEST SENSE will be sent as appropriate.

Adding two Ioctl's to scsipi's cd.c to abstract SCSI MMC devices. The ioctl's and their structures are currenly hidden from inclusion for normal userland applications to allow the MMC abstraction interface to mature first. Its useage is mainly for applications dedicated to handling and processing SCSI MMC compliant devices and their media. Examples of these are CDs, DVDs and comparable optical devices but also some magnetic swapable devices that present themselves as a SCSI MMC compliant device. Its current use is currently the to be committed in-kernel UDF filingsystem and its userland tools.

Improve disc size reporting. The current discsize thats reported is the current recorded extent and not the complete maximum extent of the disc. An empty CD/DVD disc is seen as having an invalid length and given 800 Mb size. This makes it possible to write to a CD-R using `dd' as some tend to do. However when an extent is recorded the initial recorded length is seen as valid and is thus set as absolute upperbound to read and write actions preventing extention of the disc.

Overview of changes & features: - All xfers are queued in the mid-layer, rather than doing so in an ad-hoc fashion in individual adapter drivers. - Adapter/channel resource management in the mid-layer, avoids even trying to start running an xfer if the adapter/channel doesn't have the resources. - Better communication between the mid-layer and the adapters. - Asynchronous event notification mechanism from adapter to mid-layer and peripherals. - Better peripheral queue management: freeze/thaw, sorted requeueing during recovery, etc. - Clean separation of peripherals, adapters, and adapter channels (no more scsipi_link). - Kernel thread for each scsipi_channel makes error recovery much easier (no more dealing with interrupt context when recovering from an error). - Mid-layer support for tagged queueing: commands can have the tag type set explicitly, tag IDs are allocated in the mid-layer (thus eliminating the need to use buggy tag ID allocation schemes in many adapter drivers). - support for QUEUE FULL and CHECK CONDITION status in mid-layer; the command will be requeued, or a REQUEST SENSE will be sent as appropriate.

Improve disc size reporting. The current discsize thats reported is the current recorded extent and not the complete maximum extent of the disc. An empty CD/DVD disc is seen as having an invalid length and given 800 Mb size. This makes it possible to write to a CD-R using `dd' as some tend to do. However when an extent is recorded the initial recorded length is seen as valid and is thus set as absolute upperbound to read and write actions preventing extention of the disc.

Pull up the thorpej_scsipi branch to main branch. This is a completely rewritten scsipi_xfer execution engine, and the associated changes to HBA drivers. Overview of changes & features: - All xfers are queued in the mid-layer, rather than doing so in an ad-hoc fashion in individual adapter drivers. - Adapter/channel resource management in the mid-layer, avoids even trying to start running an xfer if the adapter/channel doesn't have the resources. - Better communication between the mid-layer and the adapters. - Asynchronous event notification mechanism from adapter to mid-layer and peripherals. - Better peripheral queue management: freeze/thaw, sorted requeueing during recovery, etc. - Clean separation of peripherals, adapters, and adapter channels (no more scsipi_link). - Kernel thread for each scsipi_channel makes error recovery much easier (no more dealing with interrupt context when recovering from an error). - Mid-layer support for tagged queueing: commands can have the tag type set explicitly, tag IDs are allocated in the mid-layer (thus eliminating the need to use buggy tag ID allocation schemes in many adapter drivers). - support for QUEUE FULL and CHECK CONDITION status in mid-layer; the command will be requeued, or a REQUEST SENSE will be sent as appropriate.
