2010-02-14PPC: Add USB per default on U3Alexander Graf
Linux with CONFIG_PPC64 doesn't support ADB devices anymore, so we have to use USB for keyboard and mouse. This patch enables USB per default on U3 and adds a virtual keyboard and mouse there. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2010-02-14PPC: Get rid of segfaults in DBDMA emulationAlexander Graf
While trying to find the right channel number for the DBDMA emulation I stumbled across segmentation faults that were purely triggered by the guest. The guest should never have the possiblity to segfault us, so let's check all indirect function calls on a channel, so the code even works for channels that have not been reserved.

2010-02-14PPC: Use macio IDE controller for NewworldAlexander Graf
Per default Linux doesn't come with a lot of storage adapters enabled on Mac configurations. The one that's pretty much always present is the pmac-ide, while the cmd64x is almost never included in any distribution. So let's switch to use the MacIO based IDE controller. There is corresponding OpenBIOS code to get interrupts working properly. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2010-02-14PPC: tell the guest about the time base frequencyAlexander Graf
Our guest systems need to know by how much the timebase increases every second, so there usually is a "timebase-frequency" property in the cpu leaf of the device tree. This property is missing in OpenBIOS. With qemu, Linux's fallback timebase speed and qemu's internal timebase speed match up. With KVM, that is no longer true. The guest is running at the same timebase speed as the host. This leads to massive timing problems. On my test machine, a "sleep 2" takes about 14 seconds with KVM enabled. This patch exports the timebase frequency to OpenBIOS, so it can then put them into the device tree. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2010-02-14PPC: Make interrupts workAlexander Graf
The interrupt code as is didn't really work for me. I couldn't even convince Linux to take interrupt 9 in an interrupt-map. So let's do this right. Let's map all PCI interrupts to 0x1b - 0x1e. That way we're at least a small step closer to what real hardware does. I also took the interrupt pin to line conversion from OpenBIOS, which at least assures us we're compatible with our firmware :-).

2010-02-14PPC: Include dump of lspci -nn on real G5Alexander Graf
To ease debugging and to know what we're lacking, I found it really useful to have an lspci dump of a real U3 based G5 around. So I added a comment for it. If people don't think it's important enough to include this information in the sources, just don't apply this patch. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Michael S.

2010-02-14PPC: Use Mac99_U3 type on ppc64Alexander Graf
The "Mac99" type so far defines a "U2" based configuration. Unfortunately, there have never been any U2 based PPC64 machines. That's what the U3 was developed for. So let's split the Mac99 machine in a PPC64 and a PPC32 machine. The PPC32 machine stays "Mac99", while the PPC64 one becomes "Mac99_U3". All peripherals stay the same.

2010-02-14PPC: Uninorth config space accessorAlexander Graf
The Uninorth PCI bridge requires different layouts in its PCI config space accessors. This patch introduces a conversion function that makes it compatible with the way Linux accesses it. I also kept an OpenBIOS compatibility hack in. I think it'd be better to take small steps here and do the config space access rework in OpenBIOS later on. When that's done we can remove that hack.

2010-02-14rwhandler: simplified way to register for mem/ioMichael S. Tsirkin
Some users prefer a single callback with length passed as parameter to using b/w/l callbacks. It would maybe be cleaner to just pass length to existing callbacks but that's a lot of churn. So for now add a wrapper. For convenience use pcibus_t for address so a single callback can be used for pci io and pci memory. I did have to resort to preprocessor to reduce code duplication. It is however slightly more straightforward, and better contained than what we had with pci_host_template.h. Again, it would go away if we just passed len to existing callbacks.

2010-02-10block: add topology qdev propertiesChristoph Hellwig
Add three new qdev properties to export block topology information to the guest. This is needed to get optimal I/O alignment for RAID arrays or SSDs. The options are: - physical_block_size to specify the physical block size of the device, this is going to increase from 512 bytes to 4096 kilobytes for many modern storage devices - min_io_size to specify the minimal I/O size without performance impact, this is typically set to the RAID chunk size for arrays. - opt_io_size to specify the optimal sustained I/O size, this is typically the RAID stripe width for arrays. I decided to not auto-probe these values from blkid which might easily be possible as I don't know how to deal with these issues on migration. Note that we specificly only set the physical_block_size, and not the logial one which is the unit all I/O is described in. The reason for that is that IDE does not support increasing the logical block size and at last for now I want to stick to one meachnisms in queue and allow for easy switching of transports for a given backing image which would not be possible if scsi and virtio use real 4k sectors, while ide only uses the physical block exponent. To make this more common for the different block drivers introduce a new BlockConf structure holding all common block properties and a DEFINE_BLOCK_PROPERTIES macro to add them all together, mirroring what is done for network drivers. Also switch over all block drivers to use it, except for the floppy driver which has weird driveA/driveB properties and probably won't require any advanced block options ever. Example usage for a virtio device with 4k physical block size and 8k optimal I/O size: -drive file=scratch.img,media=disk,cache=none,id=scratch \ -device virtio-blk-pci,drive=scratch,physical_block_size=4096,opt_io_size=8192 aliguori: updated patch to take into account BLOCK events Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2010-02-10qemu-img: use the heap instead of the huge stack array for win32TeLeMan
The default stack size of PE is 1MB on win32 and IO_BUF_SIZE in img_convert() & img_rebase() is 2MB, so qemu-img will crash when doing "convert" & "rebase" on win32.

2010-02-10don't dereference NULL after failed strdupJim Meyering
Most of these are obvious NULL-deref bug fixes, for example, the ones in these files: block/curl.c net.c slirp/misc.c and the first one in block/vvfat.c. The others in block/vvfat.c may not lead to an immediate segfault, but I traced the two schedule_rename(..., strdup(path)) uses, and a failed strdup would appear to trigger this assertion in handle_renames_and_mkdirs: assert(commit->path); The conversion to use qemu_strdup in envlist_to_environ is not technically needed, but does avoid a theoretical leak in the caller when strdup fails for one value, but later succeeds in allocating another buffer(plausible, if one string length is much larger than the others). The caller does not know the length of the returned list, and as such can only free pointers until it hits the first NULL. If there are non-NULL pointers beyond the first, their buffers would be leaked. This one is admittedly far-fetched. The two in linux-user/main.c are worth fixing to ensure that an OOM error is diagnosed up front, rather than letting it provoke some harder-to-diagnose secondary error, in case of exec failure, or worse, in case the exec succeeds but with an invalid list of command line options. However, considering how unlikely it is to encounter a failed strdup early in main, this isn't a big deal. Note that adding the required uses of qemu_strdup here and in envlist.c induce link failures because qemu_strdup is not currently in any library they're linked with. So for now, I've omitted those changes, as well as the fixes in target-i386/helper.c and target-sparc/helper.c. If you'd like to see the above discussion (or anything else) in the commit log, just let me know and I'll be happy to adjust. >From 9af42864fd1ea666bd25e2cecfdfae74c20aa8c7 Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyering@redhat.com> Date: Mon, 8 Feb 2010 18:29:29 +0100 Subject: [PATCH] don't dereference NULL after failed strdup Handle failing strdup by replacing each use with qemu_strdup, so as not to dereference NULL or trigger a failing assertion. * block/curl.c (curl_open): s/\bstrdup\b/qemu_strdup/ * block/vvfat.c (init_directories): Likewise.

2010-02-10QMP: Don't leak on connection closeLuiz Capitulino
QMP's chardev event callback doesn't call json_message_parser_destroy() on CHR_EVENT_CLOSED. As the call to json_message_parser_init() on CHR_EVENT_OPENED allocates memory, we'are leaking on close.

2010-02-10QError: Don't abort on multiple faultsLuiz Capitulino
Ideally, Monitor code should report an error only once and return the error information up the call chain. To assure that this happens as expected and that no error is lost, we have an assert() in qemu_error_internal(). However, we still have not fully converted handlers using monitor_printf() to report errors. As there can be multiple monitor_printf() calls on an error, the assertion is easily triggered when debugging is enabled; and we will get a memory leak if it's not. The solution to this problem is to allow multiple faults by only reporting the first one, and to release the additional error objects. A better mechanism to report multiple errors to programmers is underway. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2010-02-10QMP: Introduce the qmp_capabilities commandLuiz Capitulino
This command will be used to enable QMP capabilities advertised by the capabilities array. Note that it will be mandatory to issue this command in order to make QMP functional (although this behavior is not being enforced by this commit). Also, as we don't have any capabilities yet, the new command doesn't accept any arguments. I will postpone the decision for a format for this until we get our first capability. Finally, this command is visible from the user Monitor too, in the meaning that you can execute it but it won't do anything. Making it only visible in QMP is beyond this series' goal, as it requires changes in unrelated places.

It might be useful to clients to check QEMU's version before negotiating features, though. To allow that, this commit adds the QEMU's version object to the greeting message.

2010-02-10segfault due to buffer overrun in usb-serialDavid S. Ahern
This fixes a segfault due to buffer overrun in the usb-serial device. The memcpy was incrementing the start location by recv_used yet, the computation of first_size (how much to write at the end of the buffer before wrapping to the front) was not accounting for it. This causes the next element after the receive buffer (recv_ptr) to get overwritten with random data.

2010-02-10audio streaming from usb devicesDavid S. Ahern
I have streaming audio devices working within qemu-kvm. This is a port of the changes to qemu. Streaming audio generates a series of isochronous requests that are repetitive and time sensitive. The URBs need to be submitted in consecutive USB frames and responses need to be handled in a timely manner. Summary of the changes for isochronous requests: 1. The initial 'valid' value is increased to 32. It needs to be higher than its current value of 10 since the host adds a 10 frame delay to the scheduling of the first request; if valid is set to 10 the first isochronous request times out and qemu cancels it. 32 was chosen as a nice round number, and it is used in the path where a TD-async pairing already exists. 2. The token field in the TD is *not* unique for isochronous requests, so it is not a good choice for finding a matching async request. The buffer (where to write the guest data) is unique, so use that value instead. 3. TD's for isochronous request need to be completed in the async completion handler so that data is pushed to the guest as soon as it is available. The uhci code currently attempts to process complete isochronous TDs the next time the UHCI frame with the request is processed. The results in lost data since the async requests will have long since timed out based on the valid parameter. Increasing the valid value is not acceptable as it introduces a 1+ second delay in the data getting pushed to the guest. 4. The frame timer needs to be run on 1 msec intervals. Currently, the expire time for the processing the next frame is computed after the processing of each frame. This regularly causes the scheduling of frames to shift in time. When this happens the periodic scheduling of the requests is broken and the subsequent request is seen as a new request by the host resulting in a 10 msec delay (first isochronous request is scheduled for 10 frames from when the URB is submitted). [ For what's worth a small change is needed to the guest driver to have more outstanding URBs (at least 4 URBs with 5 packets per URB).] Signed-off-by: David Ahern <daahern@cisco.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2010-02-10Documentation: Use UTF-8 encoding and fix one wrong encodingStefan Weil
At least for Linux distributions UTF-8 is now standard, so the QEMU documentation should use this encoding, too.

So the texinfo keywords @documentlanguage and @documentencoding now document the language and the encoding. The special character was changed to UTF-8 (it could also have been changed to an x, but the original cross looks really nice if it is displayed correctly).
