* Remove old lguest bus and drivers.Rusty Russell2007-10-23
| | | | | | | This gets rid of the lguest bus, drivers and DMA mechanism, to make way for a generic virtio mechanism. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
* Block driver using virtio.Rusty Russell2007-10-23
| | | | | | | | | | | | | | | | | | | | The block driver uses scatter-gather lists with sg[0] being the request information (struct virtio_blk_outhdr) with the type, sector and inbuf id. The next N sg entries are the bio itself, then the last sg is the status byte. Whether the N entries are in or out depends on whether it's a read or a write. We accept the normal (SCSI) ioctls: they get handed through to the other side which can then handle it or reply that it's unsupported. It's not clear that this actually works in general, since I don't know if blk_pc_request() requests have an accurate rq_data_dir(). Although we try to reply -ENOTTY on unsupported commands, ioctl(fd, CDROMEJECT) returns success to userspace. This needs a separate patch.

* Make lguest compile with CONFIG_BLOCK=n and CONFIG_NET=nRusty Russell2007-07-29
| | | | | | | | | | | Gabriel C reports lguest doesn't compile with CONFIG_BLOCK=n. Fix this by introducing a config var for the block device, which depends on LGUEST && BLOCK. Do the same for the net driver, rather then depending gratuitously on CONFIG_NET.

* ps3: Disk Storage DriverGeert Uytterhoeven2007-07-21
| | | | | | | | | | | | | | | | | Add a Disk Storage Driver for the PS3: - Implemented as a block device driver with a dynamic major - Disk names (and partitions) are of the format ps3d%c(%u) - Uses software scatter-gather with a 64 KiB bounce buffer as the hypervisor doesn't support scatter-gather Cc: Geoff Levand <geoffrey.levand@am.sony.com> Signed-off-by: Geert Uytterhoeven <Geert.Uytterhoeven@sonycom.com> Acked-by: Jens Axboe <jens.axboe@oracle.com> Cc: James Bottomley <James.Bottomley@steeleye.com> Cc: Paul Mackerras <paulus@samba.org> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes some code that became dead code after the ATARI_ACSI removal. It also indirectly fixes the following bug introduced by commit c2bcf3b8978c291e1b7f6499475c8403a259d4d6: config ATARI_SLM tristate "Atari SLM laser printer support" - depends on ATARI && ATARI_ACSI!=n + depends on ATARI Acked-by: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Adrian Bunk <bunk@stusta.de> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

* [PATCH] remove the broken BLK_DEV_SWIM_IOP driverAdrian Bunk2006-12-13
| | | | | | | | | | | | | | | | | | The BLK_DEV_SWIM_IOP driver has: - already been marked as BROKEN in 2.6.0 three years ago and - is still marked as BROKEN. Drivers that had been marked as BROKEN for such a long time seem to be unlikely to be revived in the forseeable future. But if anyone wants to ever revive this driver, the code is still present in the older kernel releases.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
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!
