| | | | | | | | | | | | | after balloon operations in an HVM guest. This removes the I/O port hack from the guest OS, and from ioemu. Also we flush on reservation *increases* as well as decreases. This is necessary until qemu-dm can demand-fault page mappings into existing valid buckets. Signed-off-by: Steven Hand <steven@xensource.com> Signed-off-by: Keir Fraser <keir@xensource.com>

* [hvm] Keep track of time offset between domain time and dom0 time.Christian Limpach2007-04-034-0/+111
| | | | | | | | | | On each rtc time update from the hvm domain, we send an ioreq request to qemu which then updates the time offset xenstore entry. The time offset is preserved across reboot and can be set on domain creation by setting the rtc_timeoffset variable in a config file.

| | | | | | | | | - convert raw "install" command to use $(INSTALL) - convert some $(INSTALL) to $(INSTALL_DATA) as appropriate - modify the specific $(INSTALL) definitions to use -p. Original patch by Ben Thomas <ben@virtualiron.com> Signed-off-by: Keir Fraser <keir@xensource.com>

* [QEMU] Clear TD status field explicitly when it's fetched.kfraser@localhost.localdomain2007-01-241-0/+8
| | | | | | | | | | | | | | | | | In current Qemu-dm, UHC will set some status bits of TD in status updating stage, but never process the status bit if relevant condition does not occur, leaving it as it is. When a TD is fetched with some status bits are set to 1, it will return to Guest OS with these bits set to 1 even this TD is executed successfully. Some Windows OS, e.g. Windows 2000, will check status bits of TD in UHC interrupt routine, treat it as a unsuccessful one if some status bits are set to 1 and discard the data. Other Windows OS just check USBSTS of UHC, ignoring status field of TD unless the value of USBSTS indicates occurrence of error. With this patch, USB mouse/tablet in Windows 2000 works correctly.

| * [IOEMU] Process reset requests before returning control to the guest.Ian Campbell2007-01-031-0/+21
| | | | | | | | | | | | | | | | | | | | | | | | Since 12899:4ae4bdee00e Xen only pays attention the first shutdown or reboot request for a domain. When a reset if requested we need to make the SCHEDOP_remote_shutdown hypercall before we return control to the guest so that it wins the "race" with the heuristic in xen/arch/x86/hvm/hvm.c:hvm_vcpu_down() which causes a powerdown.
