A customer with Fedora 22 x86_64 and qemu-ppc64le 2.1.3 running AT8.0.3 gdb connected to QEMU gdbserver (QEMU running with '-g <port-number>' option) is unable to access part of the ppc64le registers. Here is the output when trying to access VSX registers: i r $vs0 Invalid register `vs0' i r vs0 Invalid register `vs0' i r $vs32 Invalid register `vs32' i r $vr0 vr0 {uint128 = 0x00000000000000000000000000000000, v4_float = {0x0, 0x0, 0x0, 0x0}, v4_int32 = {0x0, 0x0, 0x0, 0x0}, v8_int16 = {0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0}, v16_int8 = {0x0 <repeats 16 times>}} Here are the upstream QEMU commits to fix TCG guests on all platforms: http://git.qemu.org/?p=qemu.git;a=commit;h=376dbce0e3abe456fb8c7a3cd40dc369f8b33d30 http://git.qemu.org/?p=qemu.git;a=commit;h=385abeb3e356452eace44f3fe15e18c2532dcaa7 http://git.qemu.org/?p=qemu.git;a=commit;h=87601e2d5c22d9c1fef0e09978d377f46336c1db http://git.qemu.org/?p=qemu.git;a=commit;h=ea499e71506c91aa259a7fdccf1d6b2022f5b530 http://git.qemu.org/?p=qemu.git;a=commit;h=95f5b540abd964ac3bc9c63434d07681a5a175eb http://git.qemu.org/?p=qemu.git;a=commit;h=1438eff302cbc6c85d477fd7181b8a9aeea2efd7 The following patch is also required to fix KVM guests on ppc64le platforms: http://git.qemu.org/?p=qemu.git;a=commit;h=3a4b791b4c13e02537a5cc572fa3de70bc5f68da ------- Comment From MENANTEA.com 2016-02-08 08:19 EDT------- I tried to build qemu-2.5.0-4 in koji based on fedora f24/rawhide including patches corresponding to commits described above but I get another problem on qemu build (not related to commits) referenced as: https://bugzilla.redhat.com/show_bug.cgi?id=1305512 qemu-2.4.1-7.fc23 has been submitted as an update to Fedora 23. https://bodhi.fedoraproject.org/updates/FEDORA-2016-b49aaf2c56 qemu-2.4.1-7.fc23 has been pushed to the Fedora 23 testing repository.
