2012-05-01async: Use bool for boolean struct members and remove a holeStefan Weil1-3/+3
Using bool reduces the size of the structure and improves readability. A hole in the structure was removed. Signed-off-by: Stefan Weil <sw@weilnetz.de> Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>
2012-05-01configure: Fix creation of symbolic links for MinGW toolchainStefan Weil1-11/+10
The MinGW toolchain on w32/w64 hosts does not create symbolic links, but implements 'ln -s' similar to 'cp -r'. In incremental out of tree builds, this resulted in files which were not updated when their counterparts in the QEMU source tree changed. Especially for Makefile* this happened very often. With this patch, the 'symlinked' files are now always updated for out of tree builds. Similar code was already used for the symbolic link of libcacard/Makefile. The symlink macro always removes the target before it is created again, therefore the rm command for libcacard/Makefile was redundant and is removed now. Macro symlink is also used with directories. To remove them on w32 hosts, a recursive rm is needed. v2: Quote arguments in shell function symlink, and also quote any argument which is passed to symlink and which contains macros. This should reduce the chance of accidents caused by rm -rf. Signed-off-by: Stefan Weil <sw@weilnetz.de> Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>
2012-04-28main-loop: Fix build for w32 and w64Stefan Weil1-3/+4
This patch fixes a build regression with MinGW which was introduced by commit 7c7db75576bd5a31508208f153c5aada64b2c8df. The 3rd argument of g_main_context_query must point to a gint value. Using a pointer to an uint32_t value is wrong. The timeout argument of function os_host_main_loop_wait was never used for w32 / w64.

2012-04-27qemu-iotests: add block-stream speed value test caseStefan Hajnoczi2-18/+71
Add tests to exercise the InvalidParameter 'speed' error code path, as well as the regular success case for setting the speed. The block-stream 'speed' parameter allows the speed limit of the job to be applied immediately when the job starts instead of issuing a separate block-job-set-speed command later. If the parameter has an invalid value we expect to get an error and the job is not created. It turns out that cancelling a block job is a common operation in these test cases, let's extract a cancel_and_wait() function instead of duplicating the QMP commands.

2012-04-27block: use Error mechanism instead of -errno for block_job_create()Stefan Hajnoczi4-22/+20
The block job API uses -errno return values internally and we convert these to Error in the QMP functions. This is ugly because the Error should be created at the point where we still have all the relevant information. More importantly, it is hard to add new error cases to this case since we quickly run out of -errno values without losing information. Go ahead and use Error directly and don't convert later.

Make cpu_arm_init() return a QOM ARMCPU, so that we don't need to obtain an ARMCPU through arm_env_get_cpu() in machine init code. This requires to adjust the inclusion site of cpu-qom.h and in turn, forward-looking, to homogenize its include order. cpu_init() must still return a CPUARMState for backwards and cross-target compatibility, so adjust the cpu_init macro.

2012-04-26usb: add serial number generatorGerd Hoffmann10-0/+42
This patch adds a function which creates unique serial numbers for usb devices and puts it into use. Windows guests tend to become unhappy if they find two identical usb devices in the system. Effects range from non-functional devices (with yellow exclamation mark in device manager) to BSODs. Handing out unique serial numbers to devices fixes this. With this patch applied almost all emulated devices get a generated, unique serial number. There are two exceptions: * usb-storage devices will prefer a user-specified serial number and will only get a generated number in case the serial property is unset. * usb-hid devices keep the fixed serial number "42" as it is used to signal "remote wakeup actually works".

2012-04-26usb-xhci: Use PCI DMA helper functionsDavid Gibson1-98/+92
Shortly before 1.0, we added helper functions / wrappers for doing PCI DMA from individual devices. This makes what's going on clearer and means that when we add IOMMU support somewhere in the future, only the general PCI code will have to change, not every device that uses PCI DMA. However, usb-xhci is not using these wrappers, despite being a PCI only device. This patch remedies the situation, using the pci dma functions instead of direct calls to cpu_physical_memory_{read,write}(). Likewise address parameters for DMA are changed to dma_addr_t instead of target_phys_addr_t.
