usb-storage: Forward serial number to scsi-disk · 76534da7

由 Kevin Wolf 提交于 4月 03, 2013

usb-storage takes care to fetch the USB serial number from -drive
options, but it neglected to pass its own 'serial' property to the
scsi-disk it creates. With this patch, the 'serial' qdev property and
the 'serial' option in -drive behave the same and correctly apply the
serial number on both USB and SCSI level.

hw/nand.c: Fix nand erase operation · 32aea752

由 Wendy Liang 提交于 4月 03, 2013

Usually, nand erase operation has only 2 or 3 address cycles.
We need to mask s->addr to zero unset stale high-order bytes in the nand address
before using it as the erase address.

This fixes the NAND erase operation in Linux.

cadence_uart: Flush queued characters on reset · 1db8b5ef

Reset can be used to empty the rx-fifo. As the fifo full condition is
used to return false from can_receive, queued rx data should be flushed
on reset accordingly.

pl330: Don't inhibit ES bits on INTEN · fd7f8a99

由 Peter Crosthwaite 提交于 4月 02, 2013

This if-else logic inhibits setting of the event status (ES) bits
when interrupts are enabled. This is incorrect. ES should be set
regardless on INTEN state. INTEN only inhibits the signalling of
events to PL330 threads, not setting of the ES register.

Allow xen guests to plug disks of 1 TiB or more · 9246ce88

由 Felipe Franciosi 提交于 4月 05, 2013

The current xen backend driver implementation uses int64_t variables
to store the size of the corresponding backend disk/file. It also uses
an int64_t variable to store the block size of that image. When writing
the number of sectors (file_size/block_size) to xenstore, however, it
passes these values as 32 bit signed integers. This will cause an
overflow for any disk of 1 TiB or more.

This patch changes the xen backend driver to use a 64 bit integer write
xenstore function.

Introduce 64 bit integer write interface to xenstore · 10bb3c62

由 Felipe Franciosi 提交于 4月 05, 2013

The current implementation of xen_backend only provides 32 bit integer
functions to write to xenstore. This patch adds two functions that
allow writing 64 bit integers (one generic function and another for
the backend only).

This patch also fixes the size of the char arrays used to represent
these integers as strings (originally 32 bytes, however no more than
12 bytes are needed for 32 bit integers and no more than 21 bytes are
needed for 64 bit integers).

Xen PV backend: Disable use of O_DIRECT by default as it results in crashes. · c1a88ad1

由 Alex Bligh 提交于 4月 05, 2013

Due to what is almost certainly a kernel bug, writes with O_DIRECT may
continue to reference the page after the write has been marked as
completed, particularly in the case of TCP retransmit. In other
scenarios, this "merely" risks data corruption on the write, but with
Xen pages from domU are only transiently mapped into dom0's memory,
resulting in kernel panics when they are subsequently accessed.

This brings PV devices in line with emulated devices.  Removing
O_DIRECT is safe as barrier operations are now correctly passed
through.

Xen PV backend: Move call to bdrv_new from blk_init to blk_connect · 86f425db

由 Alex Bligh 提交于 4月 05, 2013

This commit delays the point at which bdrv_new (and hence blk_open
on the underlying device) is called from blk_init to blk_connect.
This ensures that in an inbound live migrate, the block device is
not opened until it has been closed at the other end. This is in
preparation for supporting devices with open/close consistency
without using O_DIRECT. This commit does NOT itself change O_DIRECT
semantics.

arm_gic: Fix sizes of state fields in preparation for vmstate support · c3037774

由 Peter Maydell 提交于 4月 05, 2013

In preparation for switching to vmstate for migration support, fix
the sizes of various GIC state fields. In particular, we replace all
the bitfields (which VMState can't deal with) with straightforward
uint8_t values which we do bit operations on. (The bitfields made
more sense when NCPU was set differently in different situations,
but we now always model at the architectural limit of 8.)
