This is needed for supporting multiple mount points. We can find out the device names to be used with mount by checking /sys/devices/virtio-pci/virtio*/device file if the device file have value 9 then the specific virtio device can be used for mounting. ex: #cat /sys/devices/virtio-pci/virtio1/device 9 now we can mount using # mount -t 9p -o trans=virtio virtio1 /mnt/ Signed-off-by: NAneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> Signed-off-by: NEric Van Hensbergen <ericvh@gmail.com>

If the calling convention of ->timer_fn() and ->cleanup_fn() are unified across hardware versions we can drop parameters to ioat_init_channel() and unify ioat_is_dma_complete() implementations. Both ->timer_fn() and ->cleanup_fn() are modified to expect a struct dma_chan pointer. Signed-off-by: NDan Williams <dan.j.williams@intel.com>

The hardware automatically disables further interrupts after each event until rearmed. This allows a delay to be injected between the occurence of the interrupt and the running of the cleanup routine. The delay is scaled by the descriptor backlog and then written to the INTRDELAY register which specifies the number of microseconds to hold off interrupt delivery after an interrupt event occurs. According to powertop this reduces the interrupt rate from ~5000 intr/s to ~150 intr/s per without affecting throughput (simple dd to a raid6 array).

Since ioat_cleanup_preamble() and the update of the last completed descriptor are not synchronized there is a chance that two cleanup threads can see descriptors to clean. If the first cleans up all pending descriptors then the second will trigger the BUG_ON. Signed-off-by: NDan Williams <dan.j.williams@intel.com>

This makes sure that we pick the synchronous signals caused by a processor fault over any pending regular asynchronous signals sent to use by [t]kill(). This is not strictly required semantics, but it makes it _much_ easier for programs like Wine that expect to find the fault information in the signal stack. Without this, if a non-synchronous signal gets picked first, the delayed asynchronous signal will have its signal context pointing to the new signal invocation, rather than the instruction that caused the SIGSEGV or SIGBUS in the first place. This is not all that pretty, and we're discussing making the synchronous signals more explicit rather than have these kinds of implicit preferences of SIGSEGV and friends. See for example http://bugzilla.kernel.org/show_bug.cgi?id=15395 for some of the discussion. But in the meantime this is a simple and fairly straightforward work-around, and the whole if (x & Y) x &= Y; thing can be compiled into (and gcc does do it) just three instructions: movq %rdx, %rax andl $Y, %eax cmovne %rax, %rdx so it is at least a simple solution to a subtle issue.

To avoid potential problems with an empty /dev open /dev/console from rootfs instead of waiting to mount our root filesystem and mounting it there. This effectively guarantees that there will be a device node, and it won't be on a filesystem that we will ever unmount, so there are no issues with leaving /dev/console open and pinning the filesystem. This is actually more effective than automatically mounting devtmpfs on /dev because it removes removes the occasionally problematic assumption that /dev/console exists from the boot code. With this patch I was able to throw busybox on my /boot partition (which has no /dev directory) and boot into userspace without problems. The only possible negative consequence I can think of is that someone out there deliberately used did not use a character device that is major 5 minor 2 for /dev/console. Does anyone know of a situation in which that could make sense? Signed-off-by: NEric W. Biederman <ebiederm@xmission.com> Signed-off-by: NAl Viro <viro@zeniv.linux.org.uk>
