[Bug 23992] RFE: Add support for MS-DOS FPU compatibility mode
https://bugzilla.kernel.org/show_bug.cgi?id=23992 --- Comment #4 from Samuel Thibault samuel.thiba...@ens-lyon.org 2011-08-15 18:31:28 --- No, it is not a known issue. Which task(s) did you install? Note that you do not need to install GNU/Hurd to build GNU Mach, just git clone git.savannah.gnu.org:/srv/git/hurd/gnumach.git and autoreconf -i ./configure make. If you have a 64bit box, you need to cross-compile: CPP='gcc -m32 -E -x c -undef -ansi' CC='gcc -m32' LD='ld -melf_i386' ./configure --host=i686-unknown-linux-gnu Thinking again about, IIRC the kernel will just boot fine, it's only in some application use case that the issue shows up. I'll attach a patch which shows the CR0 value before and after Mach changes it. The 0x20 flag currently shows up both before and after. It should only show up after (because Mach sets it). To easily get the boot logs, pass console=com0 as kernel parameter during the multiboot command, that will direct logs to the serial port. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are watching the assignee of the bug. -- To unsubscribe from this list: send the line unsubscribe kvm in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

https://bugzilla.kernel.org/show_bug.cgi?id=23992 --- Comment #2 from Samuel Thibault samuel.thiba...@ens-lyon.org 2011-08-12 09:47:56 --- Well, yes, of course, I didn't wait for KVM to fix this bug and let people think that GNU Mach just does not work while it's actually KVM which has a bug... Right after submitting the bug I've made GNU Mach enable CR0_NE. The simplest way to test is probably to checkout revision 8d4fdfbe43628119fc87920239704fe3d240d8a2 of git://git.sv.gnu.org/hurd/gnumach.git and try to boot it e.g. using grub's multiboot command. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are watching the assignee of the bug. -- To unsubscribe from this list: send the line unsubscribe kvm in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Category: None Group: None Status: Closed Resolution: Later Priority: 5 Private: No Submitted By: Samuel Thibault (youpi_486) Assigned to: Nobody/Anonymous (nobody) Summary: Doesn't support MS-DOS compatibility FPU mode Initial Comment: Hello, Apparently, KVM always enables CR0_NE, i.e. FPU errors are always reported via the EXCP10_COPR exception rather than via the FPU interrupt. This breaks operating systems which assume MS-DOS compatability mode, i.e. exceptions are always reported via the FPU interrupt (like GNU Mach). Samuel -- Comment By: Jes Sorensen (jessorensen) Date: 2010-11-29 17:17 Message: Hi, I checked with Avi, this is still not supported but patches are welcome, so I have opened an RFE in bugzilla.kernel.org and migrated the bug there: https://bugzilla.kernel.org/show_bug.cgi?id=23992 Please use the bugzilla thread for further discussions of this problem.
