2011-03-06hw/sd.c: fix sd_set_cb() crash when bdrv == NULLAurelien Jarno
sd_set_cb() calls bdrv_is_read_only() and bdrv_is_inserted() even if no block driver is associated with the card reader. This patch fixes the issues by not setting the irq in this case, this fixes ARM versatile crash. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-03-06hw/realview: Wire up the MMC card statusPeter Maydell
Instantiate the three PL061 GPIO modules the realview boards have. Connect the MMC card status outputs of the PL181 MMC controller to both the system registers and the GPIO module which handles internal devices.

2011-03-06hw/irq: Add qemu_irq_split() so one GPIO output can feed two inputsPeter Maydell
Add a qemu_irq_split() function which allows a board to wire a single GPIO output up to two GPIO inputs. This is needed for realview boards, where the MMC card status is visible both in a system register and via a PL061 GPIO module.

2011-03-03virtio-net: Fix lduw_p() pointer argument of wrong sizeStefan Hajnoczi
A pointer to a size_t variable was passed as the void * pointer to lduw_p() in virtio_net_receive(). Instead of acting on the 16-bit value this caused failure on big-endian hosts. Avoid this issue in the future by using stw_p() instead. In general we should use ld*_p() for loading from target memory and st*_p() for storing to target memory anyway, not the other way around. Also tighten up a correct use of lduw_p() when stw_p() should be used instead in virtio_net_get_config().

2011-02-24hw/sd.c: Add missing state change for SD_STATUS, SEND_NUM_WR_BLOCKSPeter Maydell
The SD_STATUS and SEND_NUM_WR_BLOCKS commands are supposed to cause the card to send data back to the host. However sd.c was missing the state change to sd_sendingdata_state for these commands, with the effect that the Linux driver would either hang indefinitely waiting for nonexistent data (pl181) or read zeroes and provoke a qemu warning message (omap).

2011-02-21isa-bus: Remove bogus IRQ sharing checkJan Kiszka
Nothing prevented IRQ sharing on the ISA bus in principle. Not all boards supported this, neither each and every card nor driver and OS. Still, there existed valid IRQ sharing scenarios, (at least) two of them can also be found in QEMU: >2 PC UARTs and the PREP IDE buses. So remove this artificial restriction from our ISA model.

2011-02-20vhost: disable on tap link downMichael S. Tsirkin
qemu makes it possible to disable link at tap which is not communicated to the guest but causes all packets to be dropped. When vhost-net is enabled, vhost needs to be aware of both the virtio link_down and the peer link_down. we switch to userspace emulation when either is down. Signed-off-by: Michael S.

2011-02-20e1000: verify we have buffers, upfrontMichael S. Tsirkin
The spec says: Any descriptor with a non-zero status byte has been processed by the hardware, and is ready to be handled by the software. Thus, once we change a descriptor status to non-zero we should never move the head backwards and try to reuse this descriptor from hardware. This actually happened with a multibuffer packet that arrives when we don't have enough buffers. Fix by checking that we have enough buffers upfront so we never need to discard the packet midway through. Signed-off-by: Michael S.

2011-02-20e1000: clear EOP for multi-buffer descriptorsMichael S. Tsirkin
The e1000 spec says: if software statically allocates buffers, and uses memory read to check for completed descriptors, it simply has to zero the status byte in the descriptor to make it ready for reuse by hardware. This is not a hardware requirement (moving the hardware tail pointer is), but is necessary for performing an in–memory scan. Thus the guest does not have to clear the status byte. In case it doesn't we need to clear EOP for all descriptors except the last. While I don't know of any such guests, it's probably a good idea to stick to the spec. Signed-off-by: Michael S.
