2013-06-03xilinx_spips: Fix striping behaviourPeter Crosthwaite1-21/+63
The QSPI controller was using byte-wide stripes when striping across the two flashes in dual parallel mode. The real hardware however uses individual bit striping. QEMU misbehaves in the (corner) case where data is written/read in dual-parallel mode and read/written back in single mode.

2013-06-03xilinx_spips: lqspi: Dont touch config registerPeter Crosthwaite1-6/+6
The LQSPI mode is supposed to work via the automatic CS mode feature rather than manipulate CS lines itself. Now that auto CS is implemented remove LQSPIs CS mode override logic. There is still a need to manipulate the U_PAGE bit in LQSPI config register to implement dual-stack mode however.

Recent virtio refactoring in QEMU made virtio-bus become the parent bus of scsi-bus, and virtio-bus doesn't have get_fw_dev_path implementation, typename will be added to fw_dev_path by default, the new fw_dev_path could not be identified by seabios. It causes that bootindex parameter of scsi device doesn't work. This patch implements get_fw_dev_path() in BusClass, it will be called if bus doesn't implement the method, tyename will be added to fw_dev_path. If the implemented method returns NULL, nothing will be added to fw_dev_path. It also implements virtio_bus_get_fw_dev_path() to return NULL.

9P optionally uses the FS_IOC_GETVERSION ioctl to get information about a file's version (sometimes called generation number). The code checks for supported filesystems at mount time, but some paths may come from other mounted filesystems. Change it to treat unsupported paths the same as unsupported filesystems, returning 0 in both cases. Note: ENOTTY is the error code for an unsupported ioctl. This fix allows booting a linux kernel with the same / filesystem as the host; otherwise the boot fails when mounting devtmpfs.

2013-05-24memory: Rename readable flag to romd_modeJan Kiszka2-4/+4
"Readable" is a very unfortunate name for this flag because even a rom_device region will always be readable from the guest POV. What differs is the mapping, just like the comments had to explain already. Also, readable could currently be understood as being a generic region flag, but it only applies to rom_device regions. So rename the flag and the function to modify it after the original term "ROMD" which could also be interpreted as "ROM direct", i.e. ROM mode with direct access. In any case, the scope of the flag is clearer now.

2013-05-24rtl8139: flush queued packets when RxBufPtr is writtenStefan Hajnoczi1-0/+3
Net queues support efficient "receive disable". For example, tap's file descriptor will not be polled while its peer has receive disabled. This saves CPU cycles for needlessly copying and then dropping packets which the peer cannot receive. rtl8139 is missing the qemu_flush_queued_packets() call that wakes the queue up when receive becomes possible again. As a result, the Windows 7 guest driver reaches a state where the rtl8139 cannot receive packets. The driver has actually refilled the receive buffer but we never resume reception. The bug can be reproduced by running a large FTP 'get' inside a Windows 7 guest: $ qemu -netdev tap,id=tap0,... -device rtl8139,netdev=tap0 The Linux guest driver does not trigger the bug, probably due to a different buffer management strategy.

2013-05-20ide/macio: fix wrong opaque with TRIM supportAurelien Jarno1-1/+1
Commit 215e47b9 enabled TRIM by default, which revealed a bug in TRIM support for the IDE macio emulation driver, introduced in d353fb72. The call to dma_bdrv_io() is using a wrong opaque of type IDEState instead of DBDMA_io. This patch fixes that.

2013-05-15hw/pci-host/versatile.c: Provide property for forcing broken IRQ mappingPeter Maydell1-1/+13
Although we try our best to automatically detect broken versions of Linux which assume the old broken IRQ mapping we used to implement for our model of the Versatile PCI controller, it turns out that some particularly new kernels manage to outwit the autodetection. We therefore provide a property for enabling the old broken IRQ mapping, so that if users happen to have such a kernel they can work around its deficiencies with the command line option: -global versatile_pci.broken-irq-mapping=1 Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Message-id: 1368545616-22344-4-git-send-email-peter.maydell@linaro.org Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
