2019-12-18Add use of RCU for qemu_logfile.Robert Foley2-10/+64
This now allows changing the logfile while logging is active, and also solves the issue of a seg fault while changing the logfile. Any read access to the qemu_logfile handle will use the rcu_read_lock()/unlock() around the use of the handle. To fetch the handle we will use atomic_rcu_read(). We also in many cases do a check for validity of the logfile handle before using it to deal with the case where the file is closed and set to NULL. The cases where we write to the qemu_logfile will use atomic_rcu_set(). Writers will also use call_rcu() with a newly added qemu_logfile_free function for freeing/closing when readers have finished.

qemu_log_lock() now returns a handle and qemu_log_unlock() receives a handle to unlock. This allows for changing the handle during logging and ensures the lock() and unlock() are for the same file. Also in target/tilegx/translate.c removed the qemu_log_lock()/unlock() calls (and the log("\n")), since the translator can longjmp out of the loop if it attempts to translate an instruction in an inaccessible page.

2019-12-18error: make Error **errp const where it is appropriateVladimir Sementsov-Ogievskiy1-3/+3
Mostly, Error ** is for returning error from the function, so the callee sets it. However these three functions get already filled errp parameter. They don't change the pointer itself, only change the internal state of referenced Error object. So we can make it Error *const * errp, to stress the behavior.

2019-12-17object: Improve documentation of interfacesGreg Kurz1-2/+8
QOM interfaces allow a limited form of multiple inheritance, at the condition of being stateless. That is, they cannot be instantiated and a pointer to an interface shouldn't be dereferenceable in any way. This is achieved by making the QOM instance type an incomplete type, which is, as mentioned by Markus Armbruster, the closest you can get to abstract class in C. Incomplete types are widely used to hide implementation details, but people usually expect to find at least one place where the type is fully defined. The fact that it doesn't happen with QOM interfaces is quite disturbing, especially since it isn't documented anywhere as recently discussed in this thread: https://lists.gnu.org/archive/html/qemu-devel/2019-12/msg01579.html Amend the documentation in the object.h header file to provide more details about why and how to implement QOM interfaces using incomplete types.

Drop the "accel" property from MachineState, and instead desugar "-machine accel=" to a list of "-accel" options. This has a semantic change due to removing merge_lists from -accel. For example: - "-accel kvm -accel tcg" all but ignored "-accel kvm". This is a bugfix. - "-accel kvm -accel thread=single" ignored "thread=single", since it applied the option to KVM. Now it fails due to not specifying the accelerator on "-accel thread=single". - "-accel tcg -accel thread=single" chose single-threaded TCG, while now it will fail due to not specifying the accelerator on "-accel thread=single". Also, "-machine accel" and "-accel" become incompatible. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2019-12-17vl: merge -accel processing into configure_acceleratorsPaolo Bonzini1-1/+3
The next step is to move the parsing of "-machine accel=..." into vl.c, unifying it with the configure_accelerators() function that has just been introduced. This way, we will be able to desugar it into multiple "-accel" options, without polluting accel/accel.c. The CONFIG_TCG and CONFIG_KVM symbols are not available in vl.c, but we can use accel_find instead to find their value at runtime. Once we know that the binary has one of TCG or KVM, the default accelerator can be expressed simply as "tcg:kvm", because TCG never fails to initialize.

2019-12-17Remove the core bluetooth codeThomas Huth2-2197/+0
It's been deprecated since QEMU v3.1. We've explicitly asked in the deprecation message that people should speak up on qemu-devel in case they are still actively using the bluetooth part of QEMU, but nobody ever replied that they are really still using it. I've tried it on my own to use this bluetooth subsystem for one of my guests, but I was also not able to get it running anymore: When I was trying to pass-through a real bluetooth device, either the guest did not see the device at all, or the guest crashed. Even worse for the emulated device: When running qemu-system-x86_64 -bt device:keyboard QEMU crashes once you hit a key. So it seems like the bluetooth stack is not only neglected, it is completely bitrotten, as far as I can tell. The only attention that this code got during the past years were some CVEs that have been spotted there. So this code is a burden for the developers, without any real benefit anymore. Time to remove it. Note: hw/bt/Kconfig only gets cleared but not removed here yet. Otherwise there is a problem with the *-softmmu/config-devices.mak.d dependency files - they still contain a reference to this file which gets evaluated first on some build hosts, before the file gets properly recreated. To avoid breaking these builders, we still need the file around for some time. It will get removed in a couple of weeks instead.

The XSCOM bus is implemented with a QOM interface, which is mostly generic from a CPU type standpoint, except for the computation of addresses on the Pervasive Connect Bus (PCB) network. This is handled by the pnv_xscom_pcba() function with a switch statement based on the chip_type class level attribute of the CPU chip. This can be achieved using QOM. Also the address argument is masked with PNV_XSCOM_SIZE - 1, which is for POWER8 only. Addresses may have different sizes with other CPU types.

2019-12-17ppc/pnv: Pass content of the "compatible" property to pnv_dt_xscom()Greg Kurz1-1/+2
Since pnv_dt_xscom() is called from chip specific dt_populate() hooks, it shouldn't have to guess the chip type in order to populate the "compatible" property. Just pass the compat string and its size as arguments.

2019-12-17ppc/pnv: Introduce PnvChipClass::xscom_core_base() methodGreg Kurz1-0/+1
The pnv_chip_core_realize() function configures the XSCOM MMIO subregion for each core of a single chip. The base address of the subregion depends on the CPU type. Its computation is currently open-code using the pnv_chip_is_powerXX() helpers. This can be achieved with QOM. Introduce a method for this in the base chip class and implement it in child classes.

2019-12-17ppc/pnv: Introduce PnvChipClass::intc_print_info() methodGreg Kurz1-0/+1
The pnv_pic_print_info() callback checks the type of the chip in order to forward to the request appropriate interrupt controller. This can be achieved with QOM. Introduce a method for this in the base chip class and implement it in child classes. This also prepares ground for the upcoming interrupt controller of POWER10 chips.

2019-12-17ppc/pnv: Introduce PnvMachineClass::dt_power_mgt()Greg Kurz1-2/+6
We add an extra node to advertise power management on some machines, namely powernv9 and powernv10. This is achieved by using the pnv_is_power9() and pnv_is_power10() helpers. This can be achieved with QOM. Add a method to the base class for powernv machines and have it implemented by machine types that support power management instead.

2019-12-17ppc/pnv: Introduce PnvMachineClass and PnvMachineClass::compatGreg Kurz1-0/+13
The pnv_dt_create() function generates different contents for the "compatible" property of the root node in the DT, depending on the CPU type. This is open coded with multiple ifs using pnv_is_powerXX() helpers. It seems cleaner to achieve with QOM. Introduce a base class for the powernv machine and a compat attribute that each child class can use to provide the value for the "compatible" property.
