2010-02-22Fix lost serial TX interrupts. Report receive overruns.Justin T. Gibbs1-8/+20
o Implement receive overrun status. The FreeBSD uart driver relies on this status in it's probe routine to determine the size of the FIFO supported. o As per the 16550 spec, do not overwrite the RX FIFO on an RX overrun. o Do not allow TX or RX FIFO overruns to increment the data valid count beyond the size of the FIFO. o For reads of the IIR register, only clear the "TX holding register emtpy interrupt" if the read reports this interrupt. This is required by the specification and avoids losing TX interrupts when other, higher priority interrupts (usually RX) are reported first. Signed-off-by: Justin T.

2010-02-19QEMU e820 reservation patchJes Sorensen2-0/+45
Hi, Kevin and I have agreed on the approach for this one now. So here is the latest version of the patch for QEMU, submitting e820 reservation entries via fw_cfg. Cheers, Jes Use qemu-cfg to provide the BIOS with an optional table of e820 entries. Notify the BIOS of the location of the TSS+EPT range to by reserving it via the e820 table. This matches a corresponding patch for Seabios, however older versions of Seabios will default to the hardcoded address range and stay compatible with current QEMU.

2010-02-19USB HID does not support Set_IdleKevin O'Connor1-2/+10
I found that the QEMU USB keyboard support does not work properly with the Set_Idle command. Once a non-zero value is given to Set_Idle, then the keyboard reports an event on every poll - not based on the time issued in the Set_Idle command. I changed the code (see patch below) and it works for me. I'm not that familiar with the qemu internals, so I'm not sure if this is the best way to implement this feature. -Kevin Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

While trying to find the right channel number for the DBDMA emulation I stumbled across segmentation faults that were purely triggered by the guest.

2010-02-14PPC: Use macio IDE controller for NewworldAlexander Graf1-5/+11
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 Graf3-0/+19
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 Graf1-3/+11
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: Use Mac99_U3 type on ppc64Alexander Graf5-2/+83
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 Graf1-1/+66
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.

2010-02-10block: add topology qdev propertiesChristoph Hellwig12-73/+83
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>

2010-02-10segfault due to buffer overrun in usb-serialDavid S. Ahern1-6/+22
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. Ahern1-12/+55
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>
