| * dm: unplug queues in threadsMikulas Patocka2008-04-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove an avoidable 3ms delay on some dm-raid1 and kcopyd I/O. It is specified that any submitted bio without BIO_RW_SYNC flag may plug the queue (i.e. block the requests from being dispatched to the physical device). The queue is unplugged when the caller calls blk_unplug() function. Usually, the sequence is that someone calls submit_bh to submit IO on a buffer. The IO plugs the queue and waits (to be possibly joined with other adjacent bios). Then, when the caller calls wait_on_buffer(), it unplugs the queue and submits the IOs to the disk. This was happenning: When doing O_SYNC writes, function fsync_buffers_list() submits a list of bios to dm_raid1, the bios are added to dm_raid1 write queue and kmirrord is woken up. fsync_buffers_list() calls wait_on_buffer(). That unplugs the queue, but there are no bios on the device queue as they are still in the dm_raid1 queue. wait_on_buffer() starts waiting until the IO is finished. kmirrord is scheduled, kmirrord takes bios and submits them to the devices. The submitted bio plugs the harddisk queue but there is no one to unplug it. (The process that called wait_on_buffer() is already sleeping.) So there is a 3ms timeout, after which the queues on the harddisks are unplugged and requests are processed. This 3ms timeout meant that in certain workloads (e.g. O_SYNC, 8kb writes), dm-raid1 is 10 times slower than md raid1. Every time we submit something asynchronously via dm_io, we must unplug the queue actually to send the request to the device. This patch adds an unplug call to kmirrord - while processing requests, it keeps the queue plugged (so that adjacent bios can be merged); when it finishes processing all the bios, it unplugs the queue to submit the bios. It also fixes kcopyd which has the same potential problem. All kcopyd requests are submitted with BIO_RW_SYNC.

| * dm raid1: use timerMikulas Patocka2008-04-25
| | | | | | | | | | | | | | | | | | | | | | | | This patch replaces the schedule() in the main kmirrord thread with a timer. The schedule() could introduce an unwanted delay when work is ready to be processed. The code instead calls wake() when there's work to be done immediately, and delayed_wake() after a failure to give a short delay before retrying.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The balloon driver allows memory to be dynamically added or removed from the domain, in order to allow host memory to be balanced between multiple domains. This patch introduces the Xen balloon driver, though it currently only allows a domain to be shrunk from its initial size (and re-grown back to that size).

The backends run in dom0 user space. The two drivers are not in two separate patches, because the intermediate step (one driver, not the other) is somewhat problematic: the backend in dom0 needs both drivers, and will refuse to complete device initialization unless they're both present.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the xen block frontend driver is built as a module the module load is only synchronous up to the point where the frontend and the backend become connected rather than when the disk is added. This means that there can be a race on boot between loading the module and loading the dm-* modules and doing the scan for LVM physical volumes (all in the initrd). In the failure case the disk is not present until after the scan for physical volumes is complete.

| * | xen: Make xen-blkfront write its protocol ABI to xenstoreMarkus Armbruster2008-04-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Frontends are expected to write their protocol ABI to xenstore. Since the protocol ABI defaults to the backend's native ABI, things work fine without that as long as the frontend's native ABI is identical to the backend's native ABI. This is not the case for xen-blkfront running 32-on-64, because its ABI differs between 32 and 64 bit, and thus needs this fix.

Xen/x86 grant table is based on virtual address so that alloc_vm_area()/free_vm_area() are suitable. On the other hand Xen/ia64 (and Xen/powerpc) grant table is based on pseudo physical address (guest physical address) so that allocation should be done differently. The original version of xenified Linux/IA64 have its own allocate_vm_area()/free_vm_area() definitions which don't allocate vm area contradictory to those names. Now vanilla Linux already has its definitions so that it's impossible to have IA64 definitions of allocate_vm_area()/free_vm_area(). Instead introduce xen_allocate_vm_area()/xen_free_vm_area() and use them.

| | * | | forcedeth: realtek phy crossover detectionAyaz Abdulla2008-04-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes an issue seen with the realtek 8201 phy. This phy has a problem with crossover detection and it needs to be disabled. The problem only arises on certain switches. Therefore, a module parameter has been added to allow enabling crossover detection if needed. The default will be set to disabled.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch doubles the MDIO timeouts in EMAC as there are field cases where they are two short to communicate with some PHYs.

Actually, it was worse--we were spinning for a long time, and then silently failing. Instead, we take Stephen Hemminger's suggestion to try the allocation earlier, and drop the packet if it failed. We also make a couple of tweaks to how buffer descriptors are set up. Signed-off-by: Andy Fleming <afleming@freescale.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Don't need to keep a struct netxen_new_user_info on the stack when we only are interested in printing the serial_num. Change to only reading the serial_num. Signed-off-by: Harvey Harrison <harvey.harrison@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

Add MODULE_ALIAS() to the hotpluggable network platform drivers, to re-enable auto loading. NOTE: didn't change drivers/net/fs_enet/fs_enet-main.c "old binding" support. That looks problematic in the first place (it even uses the ancient "struct device_driver" binding scheme for platform_bus!) and I suspect it will vanish soonish when arch/powerpc rules the world. Also, drivers/net/ne.c would have needed more thought to sort out.
