We never actually clear the TEMT (transmit sending register empty) flag when populating the TSR. We set the flag, but since it's never cleared, setting it is sort of pointless.. I found this with a unit test case. Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

I'm not sure if the retry logic has ever worked when not using FIFO mode. I found this while writing a test case although code inspection confirms it is definitely broken. The TSR retry logic will never actually happen because it is guarded by an 'if (s->tsr_rety > 0)' but this is the only place that can ever make the variable greater than zero. That effectively makes the retry logic an 'if (0)'. I believe this is a typo and the intention was >= 0. Once this is fixed though, I see double transmits with my test case. This is because in the non FIFO case, serial_xmit may get invoked while LSR.THRE is still high because the character was processed but the retransmit timer was still active. We can handle this by simply checking for LSR.THRE and returning early. It's possible that the FIFO paths also need some attention.

Some locale settings let make fail or create wrong results because tr '[:lower:]' '[:upper:]' which is used to convert from lower to upper case depends on the locale. With locale tr_TR.UTF-8, lower case 'i' is not converted to 'I'. This results in wrong entries in config-host.h like these ones: #define CONFIG_QEMU_PREFiX "/usr/local" #define CONFIG_QEMU_BiNDiR "/usr/local/bin" This problem was reported by Emre Ersin. The same problem occurs when configure creates the target specific files config-target.mak. They get wrong declarations: TARGET_CRiS=y TARGET_i386=y TARGET_MiCROBLAZE=y TARGET_MiPS64=y TARGET_MiPS=y TARGET_UNiCORE32=y It is sufficient to restrict the conversion to the characters a-z. Using this explicit range avoids the dependency on the locale settings and is also shorter. v2: POSIX says that 'tr a-z' is unspecified outside of the POSIX locale, so we must set LC_ALL=C to make sure that we are using POSIX (hint from Eric Blake, thanks).

The idea behind qtest is pretty simple. Instead of executing a CPU via TCG or KVM, rely on an external process to send events to the device model that the CPU would normally generate. qtest presents itself as an accelerator. In addition, a new option is added to establish a qtest server (-qtest) that takes a character device. This is what allows the external process to send CPU events to the device model. qtest uses a simple line based protocol to send the events. Documentation of that protocol is in qtest.c. I considered reusing the monitor for this job. Adding interrupts would be a bit difficult. In addition, logging would also be difficult. qtest has extensive logging support. All protocol commands are logged with time stamps using a new command line option (-qtest-log). Logging is important since ultimately, this is a feature for debugging.

This lets the user specify the desired semantics. By default, the RTC will follow adjustments from the host's NTP client, and will remain in sync when the virtual machine is stopped. The previous behavior, which provides determinism with both icount and qtest, remains available with "-rtc clock=vm". pl031 supports migration, so we need to convert the time base from rtc_clock to vm_clock and back for backwards compatibility. (The rtc_clock may not be synchronized on the two machines, especially with savevm/loadvm, so the conversion is needed anyway. And since any time base will do, why not pick the one base that is backwards compatible). Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com> Signed-off-by: NPeter Maydell <peter.maydell@linaro.org>

This patch replaces the ARM_FEATURE_VFP3 test when reading MVFR registers with a test for a new feature flag ARM_FEATURE_MVFR, and sets this feature for all ARMv6K cores (ARM1156 is not a v6K core, yet supports MVFR; qemu does not support ARM1156 at this time.) MVFR0 and MVFR1 were introduced in ARM1136JF-S r1p0 (ARMv6K, VFPv2) and are present in ARM1156T2F-S (non-v6K), ARM1176JZF-S, ARM11MPCore and newer cores.
