2014-07-14serial: change retry logic to avoid concurrencyKirill Batuzov
Whenever serial_xmit fails to transmit a byte it adds a watch that would call it again when the "line" becomes ready. This results in a retry chain: serial_xmit -> add_watch -> serial_xmit Each chain is able to transmit one character, and for every character passed to serial by the guest driver a new chain is spawned. The problem lays with the fact that a new chain is spawned even when there is one already waiting on the watch. So there can be several retry chains waiting concurrently on one "line". Every chain tries to transmit current character, so character order is not messed up. But also every chain increases retry counter (tsr_retry). If there are enough concurrent chains this counter will hit MAX_XMIT_RETRY value and the character will be dropped. To reproduce this bug you need to feed serial output to some program consuming it slowly enough. A python script from bug #1335444 description is an example of such program. This commit changes retry logic in the following way to avoid concurrency: instead of spawning a new chain for each character being transmitted spawn only one and make it transmit characters until FIFO is empty. The change consists of two parts: - add a do {} while () loop in serial_xmit (diff is a bit erratic for this part, diff -w will show actual change), - do not call serial_xmit from serial_ioport_write if there is one waiting on the watch already. This should fix another issue causing bug #1335444. Signed-off-by: Kirill Batuzov <batuzovk@ispras.ru> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-07-14qemu-char: fix deadlock with "-monitor pty"Paolo Bonzini
qemu_chr_be_generic_open cannot be called with the write lock taken, because it calls client code that may call qemu_chr_fe_write. This actually happens for the monitor: 0x00007ffff27dbf79 in __GI_raise (sig=sig@entry=6) 0x00007ffff27df388 in __GI_abort () 0x00005555555ef489 in error_exit (err=<optimized out>, msg=msg@entry=0x5555559796d0 <__func__.5959> "qemu_mutex_lock") 0x00005555558f9080 in qemu_mutex_lock (mutex=mutex@entry=0x555556248a30) 0x0000555555713936 in qemu_chr_fe_write (s=0x555556248a30, buf=buf@entry=0x5555563d8870 "QEMU 2.0.90 monitor - type 'help' for more information\r\n", len=56) 0x00005555556217fd in monitor_flush_locked (mon=mon@entry=0x555556251fd0) 0x0000555555621a12 in monitor_flush_locked (mon=0x555556251fd0) monitor_puts (mon=mon@entry=0x555556251fd0, str=0x55555634bfa7 "", str@entry=0x55555634bf70 "QEMU 2.0.90 monitor - type 'help' for more information\n") 0x0000555555624359 in monitor_vprintf (mon=0x555556251fd0, fmt=<optimized out>, ap=<optimized out>) 0x0000555555624414 in monitor_printf (mon=<optimized out>, fmt=fmt@entry=0x5555559105a0 "QEMU %s monitor - type 'help' for more information\n") 0x0000555555629806 in monitor_event (opaque=0x555556251fd0, event=<optimized out>) 0x000055555571343c in qemu_chr_be_generic_open (s=0x555556248a30) To avoid this, defer the call to an idle callback, which will be called as soon as the main loop is re-entered. In order to simplify the cleanup and do it in one place only, change pty_chr_close to call pty_chr_state. To reproduce, run with "-monitor pty", then try to read from the slave /dev/pts/FOO that it creates.

2014-07-11ui/gtk: Restore keyboard focus after Page changeJohn Snow
(Resending for correct email addresses via MAINTAINERS ...) In the GTK UI, after changing focus to the qemu monitor Notebook Page, when restoring focus to the virtual machine page, the keyboard focus is lost to a hidden GTK widget. Focus can only be restored to the virtual machine by pressing "tab" or any of the four directional arrow keys. Clicking in the window or grabbing/ungrabbing input does not restore keyboard focus to the child widget. This patch adjusts the Notebook page switching callback to automatically steal keyboard focus on the Page switch event, so that keyboard input does not appear to break or disappear after tabbing to the QEMU monitor.

When the ROP function is called from cirrus_bitblt_cputovideo_next(), we pass 0 for the pitch but only operate on one line at a time. The added test was tripping because after the initial substraction, the pitch becomes negative. Make the test only trip when the height is larger than one (ie. the pitch is actually used).

But not having a name defined makes QEMU treat it as an unknown and unmigratable feature flag (as any unknown feature may possibly require state to be migrated), and disable it by default on "-cpu host".

2014-07-09watchdog: fix deadlock with -watchdog-action pausePaolo Bonzini
qemu_clock_enable says: /* Disabling the clock will wait for related timerlists to stop * executing qemu_run_timers. Thus, this functions should not * be used from the callback of a timer that is based on @clock. * Doing so would cause a deadlock. */ and it indeed does: vm_stop uses qemu_clock_enable on QEMU_CLOCK_VIRTUAL and watchdogs are based on QEMU_CLOCK_VIRTUAL, and we get a deadlock. Use qemu_system_vmstop_request_prepare()/qemu_system_vmstop_request() instead; yet another alternative could be a BH. I checked other occurrences of vm_stop and they should not have this problem. RUN_STATE_IO_ERROR could in principle (it depends on the code in the drivers) but it has been fixed by commit 2bd3bce, "block: asynchronously stop the VM on I/O errors", 2014-06-05.

2014-07-08target-ppc: Remove POWER7+ and POWER8E familiesAlexey Kardashevskiy
POWER8E is architecturally equal to POWER8 and POWER7+ is equal to POWER7. Also no user space tool makes any difference for CPU node name in the device tree (such as PowerPC,POWER7@0 vs. PowerPC,POWER7+@0). So there is no point in emulating POWER7+ and POWER8E apart from POWER7 and POWER8. Also, the previos patch implemented multiple PVR mask support per CPU class so POWER7 class now covers both POWER7 and POWER7+ CPUs, same is valid for POWER8/8E. This removes POWER7+ and POWER8E classes. This replaces references to POWER7P/POWER8E families with POWER7/POWER8 families.

2014-07-08target-ppc: Add pvr_match() callbackAlexey Kardashevskiy
So far it was enough to have a base PVR value and mask per CPU family such as POWER7 or POWER8. However there CPUs which are completely architecturally compatible but have different PVRs such as POWER7/POWER7+ and POWER8/POWER8E. For these CPUs, top 16 bits are CPU family and low 16 bits are the version. The families have PVR base values different enough so defining a mask which would cover both (or potentially more) CPUs within the family is not possible. This adds a pvr_match() callback to PowerPCCPUClass. The default handler simply compares PVR defined in the class. This implements ppc_pvr_match_power7/ppc_pvr_match_power8 callbacks for POWER7/8 families. These check for POWER7/POWER7+ and POWER8/POWER8E. This changes ppc_cpu_compare_class_pvr_mask() not to check masks but use the pvr_match() callback. Since all server CPUs use the same mask, this defines one mask value - CPU_POWERPC_POWER_SERVER_MASK - which is used everywhere now. This removes other mask definitions. This removes pvr_mask from PowerPCCPUClass as it is not used anymore. This removes pvr initialization for POWER7/8 families as it is not used to find the class, the pvr_match() callback is used instead.

2014-07-08PPC: Fix booke206 TLB with phys addrs > 32bitAlexander Graf
We were truncating physical addresses to 32bit when using qemu-system-ppc with a booke206 TLB implementation. This patch fixes that and makes the full address space available. Signed-off-by: Alexander Graf <agraf@suse.de>
2014-07-08target-ppc: Fix gdbstub for ppc64le-linux-userRichard Henderson
The bswap that's needed for system mode isn't required for user mode, and in fact breaks debugging. Signed-off-by: Richard Henderson <rth@twiddle.net> [agraf: fix apple gdbstub implementation] Signed-off-by: Alexander Graf <agraf@suse.de>
2014-07-08target-ppc: Change default cpu for ppc64le-linux-userRichard Henderson
The default, 970fx, doesn't support MSR_LE. So even though we set LE in ppc_cpu_reset, it gets cleared again in hreg_store_msr. Error out if a user-selected cpu model doesn't support LE.

2014-07-08target-ppc: KVMPPC_H_CAS fix cpu-version endianessLaurent Dufour
During KVMPPC_H_CAS processing, the cpu-version updated value is stored without taking care of the current endianess. As a consequence, the guest may not switch to the right CPU model, leading to unexpected results. If needed, the value is now converted.

pc,vhost,virtio fixes, test Bugfixes all over the place. There's a non bugfix here: re-enabling the vhost-user test, though the patch just brings back functionality that I disabled earlier to fix mingw build failures. This is now sorted, and keeping the unit test enabled seems important since the feature relies on an external server to work, so isn't easy to test. Signed-off-by: Michael S.
