* vmx: Fix the 2nd argument of cpuid_count() in vmx_cpuid_intercept()Keir Fraser2007-12-291-1/+2
| | | | | | | For input 0x00000004, the value of "*ecx" has been overwritten by the cpuid() in hvm_cpuid(), causing a bad value passed to cpuid_count(). Signed-off-by: Dexuan Cui <dexuan.cui@intel.com>
* vtpm: Fix GetCapabilityOwner functionKeir Fraser2007-12-291-0/+15
| | | | | | | | GetCapabilityOwner function's behavior is different from that of a real tpm device. By the difference, a TPM Manager in an HVM domain could not detect whether TPM device has an owner or not. Signed-off-by: Kouichi YASAKI <yasaki.kouichi@jp.fujitsu.com>

* vt-d: Only setup rmrr identity mappings of the assigned devicesKeir Fraser2007-12-281-7/+10
| | | | | | | | | | | | | | Current implementation setups identity mappings for all the rmrrs whether the assigned device has rmrr or not. It's wasteful and not necessary, because only USB controllers and UMA integarated graphics devices have rmrr. This patch only setups rmrr identity mappings of the assigned devices. If the assigned devices don't have rmrr, needn't to setup rmrr identity mapping for guest. BTW, this patch fixes the VT-d bug (Fail to boot smp Linux guest with VT-d NIC assigned on IA32e platform).

* Fix pygrub handling of many kernelsKeir Fraser2007-12-271-4/+12
| | | | | | | | If there are a large number of kernel images configured in grub.conf there will be too many to fit in the limited size pygrub display. This patch fixes this so that the list of kernels scrolls as needed. Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
* gdbstub: Various fixes.Keir Fraser2007-12-2711-93/+406
| | | | | | | | | Highlights: - Removed panics and smp stop calls in favour of an smp pause mechanism. - Added x86_64 register mapping for gdb serial protocol support. Signed-off-by: Dan Doucette <doucette.daniel@gmail.com>

* tapaio check return value from read()Keir Fraser2007-12-271-2/+18
| | | | | | | | | | | | In tools/blktap/drivers/tapaio.c there is a call to read(2) whose return value is not checked. The attached patch attempts to do something vaguely sensible in cases of error. Fully comprehensive error handling in this area would be quite tough to introduce now but at least with this change when things go wrong you stand a chance of getting some information about what happened.

* Fix xend xenstore handling.Keir Fraser2007-12-273-23/+33
| | | | | | | | | xend can get into a situation where two processes are attempting to interact with the xenstore socket, with disastrous results. Fix the two bad users of xstransact, add a big warning, and fix the destructor so future mistakes will be detected earlier. Signed-off-by: John Levon <john.levon@sun.com>
* vmx: Map the VLAPIC access page as mmio-direct in the p2m. ThisKeir Fraser2007-12-271-2/+2
| | | | | | | | prevents emulated accesses to this page, which would not be handled in the correct way (VMX handles accesses to that page in non-root mode in a very super-special way). Signed-off-by: Keir Fraser <keir.fraser@citrix.com>
* hvm: For functions which translate virtual addresses to machineKeir Fraser2007-12-279-146/+164
| | | | | | | | | | | | | addresses, page faults should only be raised when the gva->gfn translation fails. These should be distinguished from gfn->mfn translation failures. The main effect of this is to change the behaviour of functions derived from __hvm_copy(), which now returns a three-way enumeration, and also can automatically inject #PF when the gva->gfn translation fails.

* hvm: Cannot use ring_3() macro on HVM guests. It does not work becauseKeir Fraser2007-12-278-16/+28
| | | | | | | | | the CS field is not saved/restored and also because CS.RPL does not always equal the DPL (e.g., when executing in real mode). Instead we must interrogate SS.DPL, or CPL directly (SVM supports this). Signed-off-by: Keir Fraser <keir.fraser@citrix.com>

* linux: Force build failure if modules build failsKeir Fraser2007-12-201-1/+1
| | | | | | | | | | | When building a linux kernel, if the modules build fails, then the build carries on regardless. The problem is simple - the "make modules" failure is not seen by the calling make since its return value is not what is returned. Signed-off-by: Mark McLoughlin <markmc@redhat.com>
* hvm: Fix TPMD and QEMU connectionKeir Fraser2007-12-201-0/+5
| | | | | | | | | | | | 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. Before the MA_Transmit function was called, the attached patch corrected so that connection of QEMU and TPMD might be completed. Signed-off-by: Kouichi YASAKI <yasaki.kouichi@jp.fujitsu.com>

* tools/examples/block better use of losetup -rKeir Fraser2007-12-191-3/+6
| | | | | | | | | | | | Use losetup -r when the vbd is specified to be readonly, but only if -r is supported (rather than always creating a writeable losetup mapping if possible). This was inspired by (but not derived from) a diff from the Fedora 8 patchset which uses -r iff the vbd is specified as readonly. We need to be cleverer upstream because not all systems have losetup -r. Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com>

* Fix master/slave handling in xenconsoled and qemuKeir Fraser2007-12-192-66/+141
| | | | | | | | | | | | | | | Fix a number of problems with the pty handling: - make openpty() implementation work on Solaris - set raw on the slave fd, not the master, as the master doesn't have a line discipline pushed on Solaris - make sure we don't leak the slave fd returned from openpty() - don't use the 'name' argument of openpty() as it's a security risk - note behaviour of a zero read of the master on Solaris - remove pointless tcget/setattr Signed-off-by: John Levon <john.levon@sun.com> Signed-off-by: Samuel Thibault <samuel.thibault@citrix.com>

* [IA64] xenoprof: various fix on linux-xen/perfmon.cAlex Williamson2007-12-171-13/+98
| | | | | | | | | | | | | | | | Various fixes on xen/arch/ia64/linux-xen/perfmon.c - Fix starting/stopping sampling. So far IPI is used. but psr.pp isn't preserved when nested interrupt case with VTi domain. Instead timer is used. - Redefines ia64_set_pmc() to enable sampling of all xen VMM/guest kernel/guest user process. It supports only generic pmc/pmd. - Twist xenpfm_write_pmcs() It is also used when turning on pmcs. So bailing out when error is not appropriate. Even when error occures, it should continue to update next cpu's pmcs. - Add gdprintk(XENLOG_DEUBG) and BUG_ON()s. Signed-off-by: Isaku Yamahata <yamahata@valinux.co.jp>
