2008-02-06Atari floppy: Rename disk_type to atari_disk_typeGeert Uytterhoeven1-8/+8
Commit edfaa7c36574f1bf09c65ad602412db9da5f96bf Driver core: convert block from raw kobjects to core devices This moves the block devices to /sys/class/block. It will create a flat list of all block devices, with the disks and partitions in one directory. For compatibility /sys/block is created and contains symlinks to the disks. introduced a global disk_type variable in <linux/genhd.h>, causing the following compile error on Atari: drivers/block/ataflop.c:93: error: conflicting types for 'disk_type' include/linux/genhd.h:21: error: previous declaration of 'disk_type' was here Rename the local disk_type variable in drivers/block/ataflop.c to atari_disk_type, to avoid the conflict.

2008-02-06Allow auto-destruction of loop devicesDavid Woodhouse1-0/+8
This allows a flag to be set on loop devices so that when they are closed for the last time, they'll self-destruct. In general, so that we can automatically allocate loop devices (as with losetup -f) and have them disappear when we're done with them. In particular, right now, so that we can stop relying on the hackish special-case in umount(8) which kills off loop devices which were set up by 'mount -oloop'. That means we can stop putting crap in /etc/mtab which doesn't belong there, which means it can be a symlink to /proc/mounts, which means yet another writable file on the root filesystem is eliminated and the 'stateless' folks get happier... and OLPC trac #356 can be closed.

2008-02-04virtio_blk: implement naming for vda-vdz,vdaa-vdzz,vdaaa-vdzzzChristian Borntraeger1-7/+22
Am Freitag, 1. Februar 2008 schrieb Christian Borntraeger: > Right. I will fix that with an additional patch. This patch goes on top of the minor number patch. Please let me know if you want a merged patch: Currently virtio_blk creates the disk name combinging "vd" with 'a'++. This will give strange names after vdz. I have implemented names up to vdzzz - inspired by the sd.c code. That should be sufficient for now. There is one driver in the kernel (driver/s390/block/dasd_genhd.c) that implements names from dasda-dasdzzzz allowing even more disks. Maybe a janitor can come up with a common implementation usable for all kind of block device drivers. I have tested this patch with 100 disks - seems to work.

2008-02-04virtio_blk: Dont waste major numbersChristian Borntraeger1-12/+16
Rusty, currently virtio_blk uses one major number per device. While this works quite well on most systems it is wasteful and will exhaust major numbers on larger installations. This patch allocates a major number on init and will use 16 minor numbers for each disk. That will allow ~64k virtio_blk disks.

2008-02-04virtio_blk: provide getgeoChristian Borntraeger1-2/+13
Rusty, I currently try to make my guest boot from an virtio root device without having an external kernel. Some of the tools that I tried expect HDIO_GETGEO to work. The most interesting value is likely the geo.start value to get the offset of a partition. This value is filled by block/ioctl.c if fops->getgeo is set. This patch also fills in some standard values for heads, sectors and cylinders. Makes sense?

2008-02-04virtio: reset functionRusty Russell1-1/+5
A reset function solves three problems: 1) It allows us to renegotiate features, eg. if we want to upgrade a guest driver without rebooting the guest. 2) It gives us a clean way of shutting down virtqueues: after a reset, we know that the buffers won't be used by the host, and 3) It helps the guest recover from messed-up drivers. So we remove the ->shutdown hook, and the only way we now remove feature bits is via reset. We leave it to the driver to do the reset before it deletes queues: the balloon driver, for example, needs to chat to the host in its remove function. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2008-02-04virtio: explicit enable_cb/disable_cb rather than callback return.Rusty Russell1-2/+1
It seems that virtio_net wants to disable callbacks (interrupts) before calling netif_rx_schedule(), so we can't use the return value to do so. Rename "restart" to "cb_enable" and introduce "cb_disable" hook: callback now returns void, rather than a boolean. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2008-02-04virtio: simplify config mechanism.Rusty Russell1-22/+13
Previously we used a type/len pair within the config space, but this seems overkill. We now simply define a structure which represents the layout in the config space: the config space can now only be extended at the end. The main driver-visible changes: 1) We indicate what fields are present with an explicit feature bit. 2) Virtqueues are explicitly numbered, and not in the config space.

2008-01-28blk_end_request: changing xsysace (take 4)Kiyoshi Ueda1-4/+1
This patch converts xsysace to use blk_end_request interfaces. Related 'uptodate' arguments are converted to 'error'. xsysace is a little bit different from "normal" drivers. xsysace driver has a state machine in it. It calls end_that_request_first() and end_that_request_last() from different states. (ACE_FSM_STATE_REQ_TRANSFER and ACE_FSM_STATE_REQ_COMPLETE, respectively.) However, those states are consecutive and without any interruption inbetween.

2008-01-28cdrom: Add support for Sega Dreamcast GD-ROM.Adrian McMenamin1-0/+11
This patch adds support for the GD-Rom drive, SEGA's proprietary implementation of an IDE CD Rom for the SEGA Dreamcast. This driver implements Sega's Packet Interface (SPI) - at least partially. It will also read disks in SEGA's propreitary GD format. Unlike previous drivers (which were never in mainline) this uses DMA and not PIO to read disks. It is a new driver, not a refactoring of old drivers.

2007-11-14rd: fix data corruption on memory pressureChristian Borntraeger1-0/+13
We have seen ramdisk based install systems, where some pages of mapped libraries and programs were suddendly zeroed under memory pressure. This should not happen, as the ramdisk avoids freeing its pages by keeping them dirty all the time. It turns out that there is a case, where the VM makes a ramdisk page clean, without telling the ramdisk driver. On memory pressure shrink_zone runs and it starts to run shrink_active_list. There is a check for buffer_heads_over_limit, and if true, pagevec_strip is called. pagevec_strip calls try_to_release_page. If the mapping has no releasepage callback, try_to_free_buffers is called. try_to_free_buffers has now a special logic for some file systems to make a dirty page clean, if all buffers are clean. Thats what happened in our test case. The simplest solution is to provide a noop-releasepage callback for the ramdisk driver. This avoids try_to_free_buffers for ramdisk pages.
