* Allow xm to spawn vnc viewerKeir Fraser2008-07-304-50/+183
| | | | | | | | | | | | | | | | | | | | | | | | The new merged qemu no longer has the ability to spawn a vnc viewer process in the bowels of the xend/qemu stack. In this patch we provide support for this use case in a different manner - one more akin to the mechanism used for `xm console' and `xm create -c'. We introduce new xm options: xm create --vncviewer [--vncviewer-autopass] xm vncviewer [--vncviewer-autopass] These spawn a VNC viewer, obtaining the relevant information (including the port number and if you tell it your viewer supports it the password to use) directly from xenstore. Like xm console it waits in the foreground for the vnc port to become available; the timeout case isn't handled as well as it might be - it just causes the whole program (xm) to die with `Alarm clock' but this is difficult to deal with given the current structure of the xs Python lowlevel interface, which doesn't provide a timeout on the call to wait for a xenstore watch.

* vtd: Move dom0 RMRR check to intel_iommu_remove_device()Keir Fraser2008-07-301-23/+23
| | | | | | | | | | | | If put dom0 RMRR check in domain_context_unmap_one(), the devices with RMRR cannot be assigned to other domain, becuase domain_context_unmap_one() won't unmap context for them, and dom0 always owns them. This patch moves the check to intel_iommu_remove_device() which is only called by dom0 hypercall. This not only guarantees keeping RMRR mappings for dom0 during its booting, but also won't impact device assignment. Signed-off-by: Weidong Han <weidong.han@intel.com>

* xenconsoled: replace gettimeofday with clock_gettimeKeir Fraser2008-07-302-7/+7
| | | | | | | | | | | | Currently if someone changes the date on the host, xenconsoled may behave incorrectly due to the use of gettimeofday for the rate control algorithm. For example I was able to hang the console connected to a guest just setting the date forward 20 years. To solve the problem we need to use a time source that doesn't change start point, that is clock_gettime with CLOCK_MONOTONIC. The only bad side effect is that it introduces a dependency to librt, but I think is well worth it. Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com>

* x86, hvm: Fix issue with user-mode writes to read-only memory.Keir Fraser2008-07-291-6/+17
| | | | | | | | | | | | | | This patch fixes an issue where a guest could get stuck if a write to memory marked p2m_ram_ro happened from user mode. It would get misinterpreted as a user-mode page-table write, and the "dummy write" emulation necessary to skip over the instruction never got done. In looking into this, I also discovered that the user-mode page-table check is done in two places, the second (in emulate_map_dest) of which can never be reached and is just a waste of cycles. Tim Deegan requested that rather than completely removing that code, I'd leave it in for debug-builds with an added warning-print. Signed-off-by: Trolle Selander <trolle.selander@eu.citrix.com>

| | | | | | | | | | | | | | | 1. Only useful for NUMA systems, so turn it off on non-NUMA systems by default. 2. On NUMA systems, by default relate the DMA heap size to NUMA node 0 memory size (so that not all of node 0's memory ends up being 'DMA heap'). 3. Remove the 'dma emergency pool'. It's less useful now that running out of low memory isn;t as fatal as it used to be (e.g., when we needed to be able to allocate low-memory PAE page directories).

* x86: extend debug key 't' to collect useful clock skew infoKeir Fraser2008-07-281-14/+38
| | | | | | | | | | | | | | | | | By repeating "xm debug-key t; xm dmesg | tail -N" in dom0 (e.g. with the "watch" command), useful skew info about the machine can be collected, which will be very helpful for diagnosing customer problems on misbehaving machines. Patch details: 1) Min and max readings from the current sample are useless so get rid of those but retain the current maxdif (stime skew). 2) Remember max of skew, sum of skews, and a count so average skew can be displayed. 3) Also record info for cycles (tsc on x86, itc on ia64).

* x86: Roughly synchronise calls to local_time_calibration().Keir Fraser2008-07-281-3/+4
| | | | | | | | | This results in reduced skew; both max and average skew are reduced by between a factor of 2 and 3. Note that timers still fire at slightly different times because the next "round epoch" is still relative to local stime which still has some inter-processor skew.

* xend, pci passthru: Use Dstate transition to do FLR for integratedKeir Fraser2008-07-282-40/+64
| | | | | | | | | | | | | | devices without proper FLR capability. Currently integrated devices without proper FLR capability are not assignable. This is not nice since actually they may be assignable, but due to old BIOS the proper FLR capability is not exposed. We can use the previously-used Dstate transition method to do FLR for them. This works well and looks few issues are reported AFAIK. Maybe we can make a black list for the (rare) integrated devices that don't work with this method.
