f052c0f5b2 - VMX: Implemented missing SPP Misconfiguration condition (odd bits of SPP PTE entry are reserved) 
- VMX: Fix SPP walk and VMCS access memory type to WB (match memory type listed in IA32_VMX_BASIC MSR)

13aa25919a Revert "do not ignore MSR=0 even if ignore_bad_msrs is set" 
MSR=0 is valid MSR (used for Machine Check Architecture)

This reverts commit cf03c00ef0.

Add .gitattributes force eol to LF (no CR+LF) (#18) 
Add .gitattributes force eol to LF (no CR+LF).  People have different core.autocrlf configurations and It can turn Bochs repository into a mess.

text="auto" is for automatic end-of-line normalization. If Git decides that the content is text, its line endings are normalized to LF on checkin.

If the text attribute is unspecified, Git uses the core.autocrlf configuration variable to determine if the file should be converted.

So, when someone commits a file, Git guesses whether that file is a text file or not, and if it is, it will commit a version of the file where all CR + LF bytes are replaced with LF bytes.

Fix that the INIT signal remains pending even after delivery of VM-exit/#VMEXIT(INIT) (#16) 
* Clear pending INIT signal

When the INIT signal is translated into corresponding VM-exit/#VMEXIT,
the signal should no longer be marked as pending. Otherwise, the signal
would be (incorrectly) delivered again.

* Remove trailing space and fix an incorrect indent

Fix that the blocking by SMI bit maybe set when a VM-exit ends outside SMM (#15) 
* Fix that the blocking by SMI bit is set

The blocking by SMI bit of the guest interruptibility state VMCS should
not be set unless the VM-exit ends in SMM. This only happens under the
dual-monitor treatment, which is not implemented in Bochs.

* Remove trailing whitespaces

Fix two bugs around monitor/mwait
 2022-07-14 08:37:39 +03:00

b8f38eb8d3 Fix two bugs around monitor/mwait 
MONITOR relies on tickle_read_virtual to set the physical address, but it was
only doing so on TLB miss. So a MONITOR with a TLB hit would arm the most
recently accessed address instead of the requested one.

TLB invalidations disarmed the monitoring range, but didn't wake a CPU that
had already MWAIT-ed. Any instruction that invalidated TLB entries on other
CPUs could have caused an MWAIT-ing CPU to never wake.
