The 2.6 kernel supports direct writing to ide CD drives, which eliminates the need for ide-scsi. ide-scsi has been unmaintained and marked as deprecated.

* ide-floppy: allocate only toplevel packet commandsLinus Torvalds2009-01-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes the top-level function just allocate a single pc entry, and then pass it down as a pointer to all the helper functions that also need one of those "struct ide_atapi_pc" things. As far as I can tell, the use of these things never overlaps each other, BUT I DID NOT CHECK VERY CLOSELY! So I'm not guaranteeing this is correct, and I don't have the hardware. It would be good for somebody who knows the code more, and has the hardware, could please test this? With this, ide-floppy still has fairly big stack usage, but instead of idefloppy_ioctl [vmlinux]: 1208 ide_floppy_get_capacity [vmlinux]: 872 idefloppy_release [vmlinux]: 408 idefloppy_open [vmlinux]: 408 where those two first ones are at the very top of the list of stack users for me, it's now ide_floppy_get_capacity [vmlinux]: 404 ide_floppy_ioctl [vmlinux]: 364 ie they are still high, but they are no longer at the top. Borislav: Since ide_floppy_get_capacity is passed as a function pointer to other parts of the kernel (e.g., block layer) we need that ide_atapi_pc to be created on stack. Also, redid stack users numbers above. The two functions missing from Linus' original 'make stackusage' output are due to ide being rewritten/reorganized atm.

* ide: use per-device request queue locks (v2)Bartlomiej Zolnierkiewicz2009-01-02
| | | | | | | | | | | | | | | | | | | | | | | | * Move hack for flush requests from choose_drive() to do_ide_request(). * Add ide_plug_device() helper and convert core IDE code from using per-hwgroup lock as a request lock to use the ->queue_lock instead. * Remove no longer needed: - choose_drive() function - WAKEUP() macro - 'sleeping' flag from ide_hwif_t - 'service_{start,time}' fields from ide_drive_t This patch results in much simpler and more maintainable code (besides being a scalability improvement). v2: * Fixes/improvements based on review from Elias: - take as many requests off the queue as possible - remove now redundant BUG_ON() Cc: Elias Oltmanns <eo@nebensachen.de> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

* ide: don't execute the next queued command from the hard-IRQ context (v2)Bartlomiej Zolnierkiewicz2009-01-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Tell the block layer that we are not done handling requests by using blk_plug_device() in ide_do_request() (request handling function) and ide_timer_expiry() (timeout handler) if the queue is not empty. * Remove optimization which directly calls ide_do_request() for the next queued command from the ide_intr() (IRQ handler) and ide_timer_expiry(). * Remove no longer needed IRQ masking from ide_do_request() - in case of IDE ports needing serialization disable_irq_nosync()/enable_irq() was used for the (possibly shared) IRQ of the other IDE port. * Put the misplaced comment in the right place in ide_do_request(). * Drop no longer needed 'int masked_irq' argument from ide_do_request(). * Merge ide_do_request() into do_ide_request(). * Remove no longer needed IDE_NO_IRQ define. While at it: * Don't use HWGROUP() macro in do_ide_request(). * Use __func__ in ide_intr(). This patch reduces IRQ hadling latency for IDE and improves the system-wide handling of shared IRQs (which should result in more timeout resistant and stable IDE systems). It also makes it possible to do some further changes later (i.e. replace some busy-waiting delays with sleeping equivalents). v2: Changes per review from Elias Oltmanns: - fix wrong goto statement in 'if (startstop == ide_stopped)' block - use spin_unlock_irq() - don't use obsolete HWIF() macro Cc: Elias Oltmanns <eo@nebensachen.de> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
