+Subject: [Qemu-devel] [kqemu patch] get Open/NetBSD to work with the kqemu
+ accelerator
+Date: Mon, 5 Nov 2007 22:00:12 +0200
+Message-ID: <281a8e2bec2c45bce8b89bf96457995c.fa6dd951@aerenchyma>
+To: qemu-devel@nongnu.org
+
+[sorry if this is the wrong list, but I haven't figured out any public
+ address where I could send kqemu bug reports and patches]
+
+Currently, both NetBSD and OpenBSD are hanging or crashing when running
+on qemu with the kqemu accelerator enabled.
+
+This happens because both systems are using a weird scheme where they
+are loading the GDT table with LGDT up-front (with the limit set to
+the maximum), but are growing the table and actually mapping the memory
+behind it only when needed.
+(see src/sys/arch/i386/i386/gdt.c in both source trees)
+
+That is causing the kqemu accelerator to generate a page fault in
+update_dt_cache() when trying to fill its 'soft' tlb with pages that
+are beyond the real end of the GDT table.
+
+With this diff applied, NetBSD and OpenBSD seem to run fine with
+kqemu + user-only virtualization (I've tried netbsd-4.0-rc2 and
+openbsd 4.2).
+
+Full virtualization (-kernel-kqemu) doesn't work yet for different
+reasons (I think).
+
+Regards,
+Adi

+Subject: [Qemu-devel] [PATCH 1/5] kqemu: x86-64: Run 16-bit-stack-return in
+ ring 0
+Date: Fri, 29 May 2009 19:18:31 +0200
+Message-ID: <20090529171831.14265.89986.stgit@mchn012c.ww002.siemens.net>
+To: qemu-devel@nongnu.org
+
+The fix-up code for returning to 16 bit stack segments is currently
+executed in ring 1. This has the side effect that the interrupt flag
+remains cleared on return from ring 1 to the guest's ring 3 as its
+IOPL is 0 (ie. iret can only modify IF when run in ring 0).
+
+Fix this by moving the 32 bit return trampoline into ring 0.

+ exception stack
+Date: Fri, 29 May 2009 19:18:31 +0200
+Message-ID: <20090529171831.14265.74474.stgit@mchn012c.ww002.siemens.net>
+To: qemu-devel@nongnu.org
+
+This is a KQEMU upstream bug: In case the non-trivial paths of
+LOAD_SEG_CACHE in exception_return are taken for both DS and ES, the
+current code will break as it assumes to read from the monitor's DS in
+the restore code for ES. Fix this by swapping both segments on the stack
+so that ES is always restored before DS.
