Hi All,
In the updated Cygwin (3.1.4), /proc/cpuinfo still reports the microcode
version wrong.
Compare:
Cygwin:
$ uname -a
CYGWIN_NT-6.1 xxx 3.1.4(0.340/5/3) 2020-02-19 08:49 x86_64 Cygwin
$ cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 23
model name : Intel(R) Xeon(R) CPU X5470 @ 3.33GHz
stepping : 10
microcode : 0xFFFFFFF0
cpu MHz : 3340.000
Linux:
$ cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 23
model name : Intel(R) Xeon(R) CPU X5470 @ 3.33GHz
stepping : 10
microcode : 0xa0b
I checked the Windows registry, and the data stored there seem to identify the
CPU correctly.
HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\CentralProcessor\0
Component Information REG_BINARY 00000000000000000000000000000000

3GHz
VendorIdentifier REG_SZ GenuineIntel
FeatureSet REG_DWORD 0x215b3ffe
~MHz REG_DWORD 0xd05
Update Signature REG_BINARY 000000000B0A0000
Update Status REG_DWORD 0x0
Previous Update Signature REG_BINARY 00000000070A0000
Platform ID REG_DWORD 0x40
(Intel's CPU ID utility does so as well, "CPU Revision: A0B".)
Any ideas, why Cygwin is off?
Thanks,
Anton
