Most callers know which monitor type they want to have. Instead of calling monitor_init() with flags that can describe both types of monitors, make monitor_init_{hmp,qmp}() public interfaces that take specific bools instead of flags and call these functions directly.

Monitor.flags contains three different flags: One to distinguish HMP from QMP; one specific to HMP (MONITOR_USE_READLINE) that is ignored with QMP; and another one specific to QMP (MONITOR_USE_PRETTY) that is ignored with HMP. Split the flags field into three bools and move them to the right subclass. Flags are still in use for the monitor_init() interface.

Move the monitor core infrastructure from monitor/misc.c to monitor/monitor.c. This is code that can be shared for all targets, so compile it only once. What remains in monitor/misc.c after this patch is mostly monitor command implementations (which could move to hmp-cmds.c or qmp-cmds.c later) and code that requires a system emulator or is even target-dependent (including HMP command completion code). The amount of function and particularly extern variables in monitor_int.h is probably a bit larger than it needs to be, but this way no non-trivial code modifications are needed. The interfaces between all monitor parts can be cleaned up later.

Currently, struct Monitor mixes state that is only relevant for HMP, state that is only relevant for QMP, and some actually shared state. In particular, a MonitorQMP field is present in the state of any monitor, even if it's not a QMP monitor and therefore doesn't use the state. As a first step towards a clean separation between QMP and HMP, let MonitorQMP extend Monitor and create a MonitorQMP object only when the monitor is actually a QMP monitor. Some places accessed Monitor.qmp unconditionally, even for HMP monitors. They can't keep doing this now, so during the conversion, they are either changed to become conditional on monitor_is_qmp() or to assert() that they always get a QMP monitor.

Instead of mixing HMP and QMP monitors in the same function, separate the monitor creation function for both. While in theory, one could pass both MONITOR_USE_CONTROL and MONITOR_USE_READLINE before this patch and both flags would do something, readline support is tightly coupled with HMP: QMP never feeds its input to readline, and the tab completion function treats the input as an HMP command. Therefore, this configuration is useless. After this patch, the QMP path asserts that MONITOR_USE_READLINE is not set. The HMP path can be used with or without MONITOR_USE_READLINE, like before.

The "QEMU compared to other emulators" section of our documentation hasn't been updated since 2015 (and parts of the text are even older). We're clearly not very well placed to track the evolution of a dozen other emulation projects, and an inaccurate or out of date comparison doesn't serve anybody, so we're best off just removing the whole documentation section. If anybody cares strongly about maintaining a comparison page, it's probably better to do that on the project's wiki where we can update it more dynamically.

The GICv3 specification says that the GICD_TYPER.SecurityExtn bit is RAZ if GICD_CTLR.DS is 1. We were incorrectly making it RAZ if the security extension is unsupported. "Security extension unsupported" always implies GICD_CTLR.DS == 1, but the guest can also set DS on a GIC which does support the security extension. Fix the condition to correctly check the GICD_CTLR.DS bit. Signed-off-by: NPeter Maydell <peter.maydell@linaro.org> Message-id: 20190524124248.28394-3-peter.maydell@linaro.org

The GIC ID registers cover an area 0x30 bytes in size (12 registers, 4 bytes each). We were incorrectly decoding only the first 0x20 bytes.
