* [qemu] Initialize vga from within qemu for when the bios doesn't do so.chris@kneesaa.uk.xensource.com2006-07-266-29/+301
| | | | | | | | | | | | | On xen/x86, vga bios is copied to 0xC0000 by guest firmware. However on ia64 platform, native firmware depends on some initialization vga state at power on and so does guest firmware. That's why that vga bios initialization stub is required for vti domain, to match platform requirement.

We tested: in ia32 guest: a. Installation and boot of Windows XP sp2 and 2003 server in ACPI mode b when boot to both window, no yellow mark in device manger and USB, network card and IDE DMA are working. c. clean boot (without ACPI related errors) on UP and 4 vcpu rhel4u1 SMP guest and got ioapic Interrupt assigned according to ACPI DSDT table's _PRT table's GSI. To minimize the implementation efforts to satisfy the ACPI OS installation and boot, we implemented ACPI only event logical model by emulating ACPI hardware based on PIIX4 (Intel 82371ab) by: Populating the PIIX4 ACPI bridge PCI configuration space; Adding ACPI timer (required during windows installation/boot), PM1 event register block and PM1 control register block (both are required during installation/boot, shutdown, entering and leaving PM S state if adding those features later), we provided full ACPI hardware registers above using byte/word/dword access per ACPI spec requirement. The patch also fixed many existing hvm ACPI related bugs, such as warnings when boot to ACPI UP and SMP guest Linux OS; adding new ACPI _PRT table reporting PCI IRQ routing table in PIC mode, adding new _PRT table in APIC mode, that fixed no IRQ GSI cause it is forced to shutdown when OS find new device to assign IRQ without ACPI event service; The patch also fixed the ACPI DSDT table's PCI resource conflict with guest e820 table when booting and installing ACPI Windows; we also added ACPI shutdown service by incorporating the code in ACPI "hardware enable register writer" from Ben's Virtual Iron's team's patch in changeset 9989:f8d20c3e4225. We only provide minimum power management requirement support per spec-c1 and S5 for shutdown, may be S4 (hibernating which is meaningful for user to save their working section) in the future. Please note, current patch needs to have following switches in guest configuration to enable proper ACPI support a. need to add ACPI=1 (apic=1 if boot SMP Linux guest plus vcpu= number want to test) in xmexample.hvm b. need to add USB support: USB=1 and usbdevice='device' (or ='tablet') as the pm register base is static..., I will adding dynamic ACPI FADT table for pm register base pointer later. When installing guest OS in ACPI mode, need to manually tell Windows setup program to install single core ACPI HAL: After passing the 1st screen of windows setup of install Windows, the first thing you'll see at the bottom of the screen is the option to press F6 if you need to install a SCSI or RAID controller. Don't press F6. Press F5 instead. This will take you to a separate menu of Hardware Abstraction Layer's where you can choose an appropriate HAL .The choices will be: ACPI Multiprocessor PC ACPI Uniprocessor PC Advanced Configuration and Power Interface (ACPI) PC ...

* [HVM][DM] Backport the USB support from QEMU 0.8.1 to the current Xenkaf24@firebug.cl.cam.ac.uk2006-06-1214-115/+2971
| | | | | | | | | | | | | | | | | | | | | | | | | | device model. To support USB there are two new optional config lines that can be added to the guest config file: usb=1 This will enable USB without defining a specific USB device. This option is assumed and not needed if the `usbdevice' option is given. usbdevice='device' This will enable USB and also enable support for the given device. Currently, the only two devices are `mouse' (a PS/2 mouse) and `tablet' (an absolute pointing device). The advantage of `tablet' is that Windows guests will automatically recognize and support this device so specifying the config line: usbdevice='tablet' will create a mouse that works transparently with Windows guests under VNC. (Linux doesn't recognize the USB tablet yet so Linux guests under VNC will still need the Summagraphics emulation.) Signed-off-by: Don Dugger <donald.d.dugger@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | Summagraphics port to float. qemu will emulate up to 4 serial lines (COM1 - COM4). One of these lines supports a Summagraphics protocol. This has changed recently, and it's now always COM2. This patch allows the user to specify to qemu which lines should be serial lines, and the code will place the Summagraphics compatible line at just above the last specified serial line. qemu defaults serial line 0 (COM1) to be "vc", resulting in the Summagraphics support residing on COM2. This is in keeping with the current behavior. The results, via qemu command line, are: <none> COM2 -serial x COM2 -serial x -serial x COM3 -serial x -serial x -serial x COM4 -serial x -serial x -serial x -serial x <none> The results are deterministic, and allow the use of up to 4 serial lines including none with Summagraphics support. There is no change from current behavior, unless requested. Signed-off-by: Ben Thomas <ben@virtualiron.com>

| | | | | | | | | | | | There are some usage scenarios in which differing user domains want to be using different base TOD clocks. This patch adds the ability to specify the base TOD time difference.

This involves adding S5 information to the ASL file; adding ACPI I/O address processing to qemu and modifying the FADT to point to these specific I/O addresses. Note that this is a rudimentary implementation, which is expected to allow growth over time. Currently, only allow/detect writes to one of the PM registers, even though the S5 package specifies data for both. Currently, this is sufficient for the kernels tested. (Specifically, use of _PST, and _GST and other methods are unnecessary and not implemented.) Signed-off-by: Ben Thomas <ben@virtualiron.com>
* Fix the cirrus vga model to not leak memory when switching betweenkaf24@firebug.cl.cam.ac.uk2006-05-125-117/+50
| | | | | | | | | | | | | | | | | initial vga mode and linear framebuffer. When creating device model, the vga memory is allocated through xc_domain_memory_increase_reservation(), however, when switch to use linear framebuffer, we didn't free that memory, and re-allocate the vga memory through set_mm_mapping(), that caused memory leak. Now it is changed to just using qemu_malloc when create device model, and free that memory when switch to linear framebuffer. After unset_vram_mapping(), the old memory pointer should be unmapped; after set_vram_mapping(), the old memory should be freed. Signed-off-by: Yunhong Jiang <yunhong.jiang@intel.com>

This approach uses the new sched_op to handle other domains than the current domain. The new code, SCHEDOP_remote_shutdown, is very much like SCHEDOP_shutdown, but is called with the id of the domain which is to be shut down. This allows fully virtualized shutdown and para-virtualized shutdown to be identical from that point forward. A paravirtualized domain uses sched_op to shut down and set the reason code. This will send a VIRQ_DOM_EXC, which can be handled in dom0 by control software. In some ways, this resembles SIGCHILD/waitpid, and is a reasonable model. The fully virtualized case has qemu invoke xm directly. This is a different path than paravirtualized. It also removes decision and policy making choices from the rest of the control software and places it within qemu. When any dom0 logic eventually gets a VIRQ_DOM_EXC, the information about the domain is gone having been destroyed by xm. A libxenctrl wrapper, xc_shutdown_domain has been added and qemu now calls it. As a freebie, #if 0 some very verbose logging code in qemu. Totally unrelated, but as long as I was there...
