2017-05-11ppc/xics: preserve P and Q bits for KVM IRQsSam Bobroff2-0/+14
Kernel commit 17d48610ae0f ("KVM: PPC: Book 3S: XICS: Implement ICS P/Q states") added new bits to the state used by KVM IRQs. Currently, QEMU does not preserve these bits, so migrating (or otherwise saving and restoring) the guest state causes the P and Q bits to be cleared. Clearing the P bit has no effect, because the kernel will set it based on other data, but the loss of a set Q bit will cause a lost interrupt. This patch preserves the P and Q bits, correcting the problem. Signed-off-by: Sam Bobroff <sam.bobroff@au1.ibm.com> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

2017-05-11target/ppc: do not reset reserve_addr in exec_enterNikunj A Dadhania2-9/+3
In case when atomic operation is not supported, exit_atomic is called and we stop the world and execute the atomic operation. This results in a following call chain: tcg_gen_atomic_cmpxchg_tl() -> gen_helper_exit_atomic() -> HELPER(exit_atomic) -> cpu_loop_exit_atomic() -> EXCP_ATOMIC -> qemu_tcg_cpu_thread_fn() => case EXCP_ATOMIC -> cpu_exec_step_atomic() -> cpu_step_atomic() -> cc->cpu_exec_enter() = ppc_cpu_exec_enter() Sets env->reserve_addr = -1; But by the time it return back, the reservation is erased and the code fails, this continues forever and the lock is never taken. Instead set this in powerpc_excp() Now that ppc_cpu_exec_enter() doesn't have anything meaningful to do, let us get rid of the function.

2017-05-11ppc/pnv: restrict BMC object to the BMC simulatorCédric Le Goater1-1/+1
Today, when a PowerNV guest runs, it uses the sensor definitions of the BMC simulator to populate the device tree. But an external IPMI BMC could also be used and, in that case, it is not (yet) possible to retrieve the sensor list. Generating the OEM SEL event for shutdown or reboot also does not make sense as it should be generated on the BMC side. This change allows a guest to use an 'ipmi-bmc-extern' backend to the 'isa-ipmi-bt' device and a 'chardev' for transport such as : -chardev socket,id=ipmi0,host=localhost,port=9002,reconnect=10 \ -device ipmi-bmc-extern,id=bmc0,chardev=ipmi0 \ -device isa-ipmi-bt,bmc=bmc0,irq=10 and connect to a BMC simulator, the OpenIPMI ipmi_sim simulator for instance.

2017-05-09test-qga: Actually test 0xff sync bytesEric Blake2-7/+42
Commit 62c39b3 introduced test-qga, and at face value, appears to be testing the 'guest-sync' behavior that is recommended for guests in sending 0xff to QGA to force the parser to reset. But this aspect of the test has never actually done anything: the qmp_fd() call chain converts its string argument into QObject, then converts that QObject back to the actual string that is sent over the wire - and the conversion process silently drops the 0xff byte from the string sent to QGA, thus never resetting the QGA parser. An upcoming patch will get rid of the wasteful round trip through QObject, at which point the string in test-qga will be directly sent over the wire. But fixing qmp_fd() to actually send 0xff over the wire is not all we have to do - the actual QMP parser loudly complains that 0xff is not valid JSON, and sends an error message _prior_ to actually parsing the 'guest-sync' or 'guest-sync-delimited' command. With 'guest-sync', we cannot easily tell if this error message is a result of our command - which is WHY we invented the 'guest-sync-delimited' command. So for the testsuite, fix things to only check 0xff behavior on 'guest-sync-delimited', and to loop until we've consumed all garbage prior to the requested delimiter, which is compatible with the documented actions that a real QGA client is supposed to do. Ideally, we'd fix the QGA JSON parser to silently ignore 0xff rather than sending an error message back, at which point we could enhance this test for 'guest-sync' as well as for 'guest-sync-delimited'. But for the sake of this patch, our testing of 'guest-sync' is no worse than it was pre-patch, because we have never been sending 0xff over the wire in the first place.

2017-05-08trace: disallow more than 10 arguments per trace eventDaniel P. Berrange1-0/+4
The UST trace backend can only cope with upto 10 arguments. To ensure we don't exceed the limit when UST is not compiled in, disallow more than 10 arguments upfront. This prevents the case where: commit 0fc8aec7de64f2bf83a274a2a38b938ce03425d2 Author: Zhang Chen <zhangchen.fnst@cn.fujitsu.com> Date: Tue Apr 18 10:20:20 2017 +0800 COLO-compare: Optimize tcp compare trace event Optimize two trace events as one, adjust print format make it easy to read. rename trace_colo_compare_pkt_info_src/dst to trace_colo_compare_tcp_info. regressed the fix done in commit 2dfe5113b11ce0ddb08176ebb54ab7ac4104b413 Author: Alex Bennée <alex.bennee@linaro.org> Date: Fri Oct 28 14:25:59 2016 +0100 net: split colo_compare_pkt_info into two trace events It seems there is a limit to the number of arguments a UST trace event can take and at 11 the previous trace command broke the build. Split the trace into a src pkt and dst pkt trace to fix this.

2017-05-08gdbstub: implement remote debugging protocol escapes for command receiveDoug Gale1-9/+99
- decode escape sequences - decompress run-length encoding escape sequences - report command parsing problems to output when debug output is enabled - reject packet checksums that are not valid hex digits - compute the checksum based on the packet stream, not based on the decoded packet Tested with GDB and QtCreator integrated debugger on SMP QEMU instance.
