2010-03-19Convert atexit users to exit_notifierAnthony Liguori
All of these users have global state so we really don't see a benefit from exit_notifier. However, using exit_notifier means that there's one less justification for having global state in the first place. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-03-19Rewrite mouse handlers to use QTAILQ and to have an activation functionAnthony Liguori
And convert usb-hid to use it (to avoid regression with bisection) Right now, when we do info mice and we've added a usb tablet, we don't see it until the guest starts using the tablet. We implement this behavior in order to provide a means to delay registration of a mouse handler since we treat the last registered handler as the current handler. This is a usability problem though as we would like to give the user feedback that they've either 1) not added an absolute device 2) there is an absolute device but the guest isn't using it 3) we have an absolute device and it's active. By using QTAILQ and having an explicit activation function that moves the handler to the front of the queue, we can implement the same semantics as before with respect to automatically switching to usb tablet while providing the user with a whole lot more information.

2010-03-18Replace assert(0) with abort() or cpu_abort()Blue Swirl
When building with -DNDEBUG, assert(0) will not stop execution so it must not be used for abnormal termination. Use cpu_abort() when in CPU context, abort() otherwise. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2010-03-17hw/usb-msd: fix some usb requestsArnaud Patard (Rtp)
The usb-msd device emulation needs some small tweaks in the requests emulations. For instance, the reset/maxlun requests are class/interface specific so requests for them with the type class and recipient interface bits sets have to be handled.

2010-03-17disentangle tcg and deadline calculationPaolo Bonzini
Just tell main_loop_wait whether to be blocking or nonblocking, so that there is no need to call qemu_cpus_have_work from the timer subsystem.

2010-03-17balloon: Do not save VM state wrt asynchronous virtio operationsAdam Litke
When working with the VM state (for loadvm/savevm and migration), it is not valid to load and store pointers since the validity of those pointers cannot be assured in the new qemu address space. Therefore, virtio_balloon_save() and virtio_balloon_load() must not handle the stats-related fields in struct VirtIOBalloon. If a memory stats request is in-flight at the time of a migration or savevm, the request will not complete and should be resubmitted once migration or loadvm completes. Note that this extremely small race window can only be triggered using QMP so it is not possible to hang the user monitor.

2010-03-17block: add logical_block_size propertyChristoph Hellwig
Add a logical block size attribute as various guest side tools only increase the filesystem sector size based on it, not the advisory physical block size. For scsi we already have support for a different logical block size in place for CDROMs that we can built upon. Only my recent block device characteristics VPD page needs some fixups. Note that we leave the logial block size for CDROMs hardcoded as the 2k value is expected for it in general. For virtio-blk we already have a feature flag claiming to support a variable logical block size that was added for the s390 kuli hypervisor. Interestingly it does not actually change the units in which the protocol works, which is still fixed at 512 bytes, but only communicates a different minimum I/O granularity. So all we need to do in virtio is to add a trap for unaligned I/O and round down the device size to the next multiple of the logical block size. IDE does not support any other logical block size than 512 bytes. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2010-03-17Large page TLB flushPaul Brook
QEMU uses a fixed page size for the CPU TLB. If the guest uses large pages then we effectively split these into multiple smaller pages, and populate the corresponding TLB entries on demand. When the guest invalidates the TLB by virtual address we must invalidate all entries covered by the large page. However the address used to invalidate the entry may not be present in the QEMU TLB, so we do not know which regions to clear. Implementing a full vaiable size TLB is hard and slow, so just keep a simple address/mask pair to record which addresses may have been mapped by large pages. If the guest invalidates this region then flush the whole TLB. Signed-off-by: Paul Brook <paul@codesourcery.com>
2010-03-16monitor: convert do_device_add() to QObjectMarkus Armbruster
2010-03-16monitor: Use argument type 'O' for device_addMarkus Armbruster
While there, improve the params help text.
2010-03-16qemu-option: Move the implied first name into QemuOptsListMarkus Armbruster
We sometimes permit omitting the first option name, for example -device foo is short for -device driver=foo. The name to use ("driver" in the example) is passed as argument to qemu_opts_parse(). For each QemuOptsList, we use at most one such name. Move the name into QemuOptsList, and pass whether to permit the abbreviation. This ensures continued consistency, and simplifies the commit after next in this series.
2010-03-16error: Convert do_device_add() to QErrorMarkus Armbruster
Conversion to QObject is still missing.
2010-03-16Revert "qdev: Use QError for 'device not found' error"Markus Armbruster
This reverts commit 3ced9f7a36189aed94d8bf86f3f5087a53012455. The next commit will convert all of qdev_device_add() to QError, and it'll be clearer with this partial conversion reverted.

2010-03-16qdev: convert setting device properties to QErrorMarkus Armbruster
2010-03-16qdev: Hide "ptr" properties from usersMarkus Armbruster
Users can't set them, so qdev_device_help() shouldn't list them. Fix that. Also make qdev_prop_parse() hide them instead of printing a meaningless "has no parser" error message. Their value means nothing to users, so qdev_print_props() shouldn't print it. Fix by removing their print method. Their only use is dirty hacks. Document that.
2010-03-16qdev: Hide "no_user" devices from usersMarkus Armbruster
Users can't create them, so qdev_device_help() shouldn't list them. Fix that. Also make qdev_device_add() pretend they don't exist. Before, it rejected them with a "can't be added via command line" message, which wasn't quite right for monitor command device_add.
2010-03-16qdev: Factor qdev_create_from_info() out of qdev_create()Markus Armbruster
To make it obvious that -device and device_add can't die in hw_error().
2010-03-16qdev: Fix -device and device_add to handle unsuitable bus gracefullyMarkus Armbruster
"device_add isa-serial,bus=pci.0" kills QEMU. Not good.
2010-03-16error: Rename qemu_error_new() to qerror_report()Markus Armbruster
2010-03-16error: Replace qemu_error() by error_report()Markus Armbruster
error_report() terminates the message with a newline. Strip it it from its arguments. This fixes a few error messages lacking a newline: net_handle_fd_param()'s "No file descriptor named %s found", and tap_open()'s "vnet_hdr=1 requested, but no kernel support for IFF_VNET_HDR available" (all three versions). There's one place that passes arguments without newlines intentionally: load_vmstate(). Fix it up.
2010-03-16error: Don't abuse qemu_error() for non-error in scsi_hot_add()Markus Armbruster
Commit 30d335d6 converted an informational message from monitor_printf() to qemu_error(), probably because the latter doesn't need a mon argument. A later commit will make qemu_error() print additional stuff that is only appropriate for proper errors, and then this will break. Clean it up.
2010-03-16error: Don't abuse qemu_error() for non-error in qbus_find()Markus Armbruster
qbus_find() adds an informational line to error messages, and prints both lines with one qemu_error(). Use error_printf() for the informational line instead. While there, simplify: instead of printing buffers filled by qbus_list_bus() and qbus_list_dev() in one go, make them print it.
2010-03-16error: Don't abuse qemu_error() for non-error in qdev_device_help()Markus Armbruster
qdev_device_help() prints device information with qemu_error(). A later commit will make qemu_error() print additional stuff that is only appropriate for proper errors, and then this will break. Use error_printf() instead. While there, simplify: instead of printing a buffer filled by qdev_print_devinfo() in one go, make qdev_print_devinfo() print it.
2010-03-16error: Move qemu_error & friends into their own headerMarkus Armbruster
2010-03-16block: Simplify usb_msd_initfn() test for "can read bdrv key"Markus Armbruster
The old test assumes that "hotplugged" implies "we have a current monitor for reading the key". This is in fact true, but it's not obviously true. Aside: if it were false, we could pass a null pointer to monitor_read_bdrv_key_start(), which would then crash. The previous commit permits us to check for "we have a current monitor" directly, so do that.
2010-03-16pc: Factor common code out of pc_boot_set() and cmos_init()Markus Armbruster
Code duplicated in commit 0ecdffbb. The two versions are similar, but not identical: * cmos_init() reports errors to stderr, pc_boot_set() via qemu_error(). The latter is fine for both, so pick that for the common code. * cmos_init() obeys fd_bootchk, pc_boot_set() ignores it. Make it a parameter of the common code.
2010-03-16pc: Fix error reporting for -boot onceMarkus Armbruster
Commit 0ecdffbb created pc_boot_set() for use from monitor command "boot_set", via qemu_boot_set(). pc_boot_set() reports errors to cur_mon, which works fine for monitor code. Commit e0f084bf reused the function int reset handler restore_boot_devices(). Use of cur_mon is problematic in that context. For instance, the "Too many boot devices for PC" error for "-boot order=abcdefgh,once=c" goes to the monitor instead of stderr. The monitor may not even exist. Fix by switching to qemu_error().
2010-03-16load_elf: replace the address addend by a translation functionAurelien Jarno
A few machines need to translate the ELF header addresses into physical addresses. Currently the only possibility is to add a value to the addresses. This patch replaces the addend argument by and a translation function and an opaque passed to the function. A NULL function does not translate the address. The patch also convert all machines that have an addend, simplify the PowerPC kernel loading and fix the MIPS kernel loading using this new feature. Other machines may benefit from this feature.

Real pcnet device (AT2450) apparently has subsystem device and vendor id set to 0, this is out of spec (which requires that vendor id is obtained from PCI SIG) but windows xp driver seems to need this in order to associate. qemu sets pci subsystem id to qumranet/qemu since d350d97d196a632b6c7493acf07a061017fc6f7d, debian does not yet have this patch. https://bugzilla.redhat.com/show_bug.cgi?id=521247 Signed-off-by: Michael S.
