* hvm, ioemu: Fix the ide/cdrom emulation error on FC7 guest.Keir Fraser2008-01-221-1/+4
| | | | | | | | | | | | | | | | | | | | | | The new libata-eh in the Linux kernel is throwing a fit over the QEMU cdrom device for two reasons: 1) DRQ can be set with ERR_STAT set. This is a violation of the ATAPI state machine. 2) After a TEST_UNIT_READY ATAPI command is sent ERR_STAT is getting set which is correct. But, when the OS issues another ATAPI command ERR_STAT is still set. Which is bad since the next expected command from the OS is REQUEST_SENSE to find out why ERR_STAT is set. bug this fixes: https://bugzilla.novell.com/show_bug.cgi?id=3D291775 Signed-off-by: Brandon Philips <bphilips@suse.de> Porting this qemu fix to xen.

* hvm: Extboot support for XenKeir Fraser2008-01-173-1/+129
| | | | | | | | | This patch adds extboot to Xen. It should be pretty harmless as the moment because it's never enabled. extboot allows arbitrary block devices to be used to boot guests including SCSI and PV disks. I've tested it with both Windows and Linux guests in QEMU. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
* HVM vif without bridge.Keir Fraser2008-01-081-1/+1
| | | | | | | | | | | | | | When using xen without a bridge but NAT or routing, HVM domains can't boot, and qemu-dm-n.log contains: config qemu network with xen bridge for tap0 xenbr0 bridge xenbr0 does not exist! That's because the qemu-ifup script always tries to add the vif to a default-named xenbr0 bridge. On the contrary, PV domains just work fine with the same configuration file except HVM parameters.

| | | | | | | | | | | | In HVM domain, MA_Transmit function in tcgbios sometimes become an error (TCG_NO_RESPONSE). The cause of the error is not to make connection of QEMU and TPMD instance within a timeout of MA_Transmit function.

The symptoms include video malfunction after restore, including black screen (which can often be fixed by asking the guest to redraw) but also missing font setup etc. The attached patch fixes this by saving the entire VGA memory buffer, just like the Xen ioemu Cirrus emulator does. I have reinterpreted the `is_vbe' byte, which is related to CONFIG_BOCHS_VBE, as a general flags word. This enables my code to allow old images to be restored (albeit with loss of VGA memory), by using another bit in that word to indicate whether the VGA memory dump is present.

* [QEMU-DM] Upgrade emulated UART to 16550A.Keir Fraser2007-12-051-199/+276
| | | | | | | | | | | | | | | | | | | | This patch adds 16550 emulation to qemu-dm. I still consider it a work in progress, but from my testing, it consistently performs better than the old code already, sometimes considerably so (on my laptop, dumping out data over serial from a HVM DomU -> pty in Dom0 was up to 5.3 times faster than with the old 16450 code). I can consistenly reach full 115200 baud speeds over physical serial lines when the virtual device is backed by a phys port, which I never could with the old code. There are still some things to be done. I want to add proper error handling, so that overflow/framing & parity errors on the physical port get detected and reported by the virtual port. Also, now that FIFOs are in place, I believe performance could be improved significantly by putting some code into the hypervisor so that reads & writes from the FIFOs don't have to exit into qemu-dm at all. I'm also reading up on the specs for newer uarts with deeper FIFOs. Signed-off-by: Trolle Selander <trolle.selander@gmail.com>
* [QEMU-DM] Modem control line & msl/mcr register support.Keir Fraser2007-12-053-12/+144
| | | | | | | | | | | | | | | | | | | | | This patch enables handling of the modem/flow control lines of a serial port when the backend for the virtual port is a physical serial port. During initialization, it tries to load the msr with the detected status from the real port (this is consistent with physical uart, which starts with its msr values set according to the status of the modem status lines). If the ioctl returns -ENOTSUP, then the code assumes the backend is not a real serial port and will disable any further attempts to manipulate or read the physical port's line status. It's tries to be as "correct" as possible in its msr/msl handling, with the exception of modem line status change interrupts. A real 16550 uart apparently have a delay time of 250ns between when a modem status line changes and the IRQ line goes high. In this patch, an "idle" port is polled for line status changes only if the guest has enabled UART_IER_MSI is enabled, and only polled every 10 ms.

* qemu vnc auth 3/4: Add VNC auth support from upstream QEMUKeir Fraser2007-10-309-48/+1543
| | | | | | | | | | | | | | | | | | | This patch adds in the upstream QEMU VNC authentication code. This spports the previous VNC password auth scheme, as well as the VeNCrypt protocol extension. The latter allows for performing a TLS handshake, and client verification of the server identify using x509 certificates. It is also possible for the server to request a client certificate and validate that as a simple auth scheme. The code depends on GNU TLS for SSL APIs, and the configure script will auto-detect this. The image.py code is changed to deal with the new syntax for the -vnc option. In particular password authentication is now enabled by giving the 'password' flag, eg -vnc 0.0.0:1,password Signed-off-by: Daniel P. Berrange <berrange@redhat.com>

* x86, hvm: Improve standard VGA performanceKeir Fraser2007-10-262-5/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch improves the performance of Standard VGA, the mode used during Windows boot and by the Linux splash screen. It does so by buffering all the stdvga programmed output ops and memory mapped ops (both reads and writes) that are sent to QEMU. We maintain locally essential VGA state so we can respond immediately to input and read ops without waiting for QEMU. We snoop output and write ops to keep our state up-to-date. PIO input ops are satisfied from cached state without bothering QEMU. PIO output and mmio ops are passed through to QEMU, including mmio read ops. This is necessary because mmio reads can have side effects. I have changed the format of the buffered_iopage. It used to contain 80 elements of type ioreq_t (48 bytes each). Now it contains 672 elements of type buf_ioreq_t (6 bytes each). Being able to pipeline 8 times as many ops improves VGA performance by a factor of 8. I changed hvm_buffered_io_intercept to use the same registration and callback mechanism as hvm_portio_intercept rather than the hacky hardcoding it used before. In platform.c, I fixed send_timeoffset_req() to sets its ioreq size to 8 (rather than 4), and its count to 1 (which was missing).

* pv-qemu 8/10: Add pv console to QEMU paravirt machineKeir Fraser2007-10-255-1/+468
| | | | | | | | | | | | | | | | This patch adds a paravirt console driver to qemu-dm. This is used when the QEMU machine type is 'xenpv', connecting to the ring buffer provided by the guest kernel. The '-serial' command line flag controls how the guest console is exposed. For parity with xenconsoled the '-serial pty' arg can be used. For guests which are running a qemu-dm device model, the xenconsoled daemon is no longer needed for guest consoles. The code for the xen_console.c is based on the original code in tools/console/daemon/io.c, but simplified; since its only dealing with a single guest there's no state tracking to worry about.
