Summary: ntdll: NtQuerySystemInformation(SYSTEM_PROCESSOR_PERFORMANCE_ INFORMATION) should provide NT-style 100ns units (.NET 1.x CLR) Product: Wine Version: 1.3.0 Platform: x86 URL: http://www.microsoft.com/DownLoads/details.aspx?family id=D7158DEE-A83F-4E21-B05A-009D06457787 OS/Version: Linux Status: NEW Keywords: dotnet, download, Installer Severity: normal Priority: P2 Component: ntdll AssignedTo: wine-bugs@winehq.org ReportedBy: focht@gmx.net
Hello,
after bug 17084 (.NET 1.0: imagehlp.ImageGetDigestStream needs more flesh (assembly registration fails)) was fixed, the installer still fails.
The first blocker is now the presence of some .NET registry keys that ought to help Mono but break the MS installer itself (path to v1.0.xxx Microsoft CLR core library is incorrectly constructed, leading to mscorwks.dll load failure). You can work around by deleting the following key before running the installer:
--- snip --- $ wine reg delete "HKLM\Software\Microsoft.NETFramework" --- snip ---
Near the end, the installer spawns "regasm.exe" tool several times to register various assemblies. Unfortunately the tool crashes with division by zero (+tid,+seh,+relay):
--- snip --- ... 0040:Call ntdll.NtQuerySystemInformation(00000008,031ce960,00000060,00000000) ret=792cf160 0040:Ret ntdll.NtQuerySystemInformation() retval=00000000 ret=792cf160 0040:trace:seh:raise_exception code=c0000094 flags=0 addr=0x79243177 ip=79243177 tid=0040 0040:trace:seh:raise_exception eax=00000000 ebx=ffffffff ecx=00000000 edx=00000000 esi=00000022 edi=00000001 0040:trace:seh:raise_exception ebp=031ce9f0 esp=031ce940 cs=0023 ds=002b es=002b fs=0063 gs=006b flags=00010246 --- snip ---
Interestingly there are other calls from the same addresses that don't crash:
--- snip --- 0020:Call ntdll.NtQuerySystemInformation(00000008,0320e960,00000060,00000000) ret=792cf160 0020:trace:ntdll:NtQuerySystemInformation (0x00000008,0x320e960,0x00000060,(nil)) 000d:Call KERNEL32.SwitchToThread() ret=7929a604 000d:Ret KERNEL32.SwitchToThread() retval=00000001 ret=7929a604 0020:Ret ntdll.NtQuerySystemInformation() retval=00000000 ret=792cf160 0020:Call KERNEL32.Sleep(000001f4) ret=792d00bc --- snip ---
Using additional "printf" style debugging to dump kernel+user+idle jiffies I noticed the crashes happen when the values accumulated only small changes in capture intervals. It seems the CLR employs some kind of cpu resource utilization calculation (using certain capture intervals) that breaks if the ticks/time units increment fall below some threshold.
Windows NT accounts SYSTEM_PROCESSOR_PERFORMANCE_INFORMATION values in 100ns units. See: http://msdn.microsoft.com/en-us/library/ms724509.aspx
I fixed dlls/ntdll/nt.c:NtQuerySystemInformation( SystemProcessorPerformanceInformation class) to convert jiffies to NT-style 100-ns units and it helped to keep the .NET CLR CPU usage calculation happy and to not let the regasm tool crash anymore (installer succeeded).
