TODO: fix lgdt macro to work with GAAS and ML
Works with PIIX3 and cdrom on AHCI or SCSI controller
When cdrom is on IDE controller it doesn't seem to work
This command was removed in commit baa47fa5e0
because there was no way to get the CRx registers from a CONTEXT structure.
Previous code was also displaying current GDTR/LDTR and IDT.
Rewrite the code to use KdSystemDebugControl(SysDbgReadControlSpace, ...)
to get CRx, GDTR/LDTR and IDT values just before entering debugger.
WinDBG can do some local debugging using 'windbg -kl'. In that case,
WinDBG tries to directly use NtSystemDebugControl. If this function
returns an error, WinDBG extracts a driver from its resources.
WinDBG will send IOCTLs to this driver, and this driver will call
KdSystemDebugControl.
However, on livecd (where %SYSTEMROOT% is read-only), WinDBG is unable
to extract the driver from its resources, and can't use the driver to
call KdSystemDebugControl.
As a work-around, allow all control classes in NtSystemDebugControl
in case of livecd.
WinDBG local debugging now also works on livecd (windbg -kl).
- Add SEH probing for user buffer
- Mark some classes as i386 only
- Explicitly return STATUS_NOT_IMPLEMENTED on disabled classes (must use KdSystemDebugControl instead)
- Explicitly return STATUS_NOT_IMPLEMENTED on not implemented classes
- Return STATUS_INVALID_INFO_CLASS on all other classes
URLs are getting old. We have to
update URLs for documentation
purpose.
JIRA issue: CORE-19963
- Refresh old URLs.
- Add " (DEAD_LINK)" labels
to dead links.
- Use MS Learn links rather
than MSDN ones.
- Some dead links revived by
Web Archive.
- Don't change Wine Tests
and Wine Sync.
- Don't change 3rd party libraries.
- Don't append "redirected" labels.
The VolumePath buffer returned by IOCTL_MOUNTMGR_QUERY_DOS_VOLUME_PATH
contains one string stored as a multi-NUL-terminated string, whose
total length is given by its `MultiSzLength` member.
The DosName UNICODE_STRING just returns the (single) string as a normal
NUL-terminated string. So, we need to remove the two NUL-terminators
from the `MultiSzLength` count to retrieve the correct length.
PAGE_ROUND_DOWN macro seems to not work correctly with LONGLONG values. It creates some random freezes in the 1st-stage setup after commit 69bf140506.
It's fixed by creating PAGE_ROUND_UP_64 and PAGE_ROUND_DOWN_64 macros for 64-bit only data types.
