2021-07-02hw/mips/jazz: Map the UART devices unconditionallyPhilippe Mathieu-Daudé
When using the Magnum ARC firmware we can see accesses to the UART1 being rejected, because the device is not mapped: $ qemu-system-mips64el -M magnum -d guest_errors,unimp -bios NTPROM.RAW Invalid access at addr 0x80007004, size 1, region '(null)', reason: rejected Invalid access at addr 0x80007001, size 1, region '(null)', reason: rejected Invalid access at addr 0x80007002, size 1, region '(null)', reason: rejected Invalid access at addr 0x80007003, size 1, region '(null)', reason: rejected Invalid access at addr 0x80007004, size 1, region '(null)', reason: rejected Since both UARTs are present (soldered on the board) regardless of whether there are character devices connected, map them unconditionally. (This code pre-dated commit 12051d82f004 which made it safe to pass NULL in as a chardev to serial devices.)

2021-03-08clock: Add ClockEvent parameter to callbacksPeter Maydell
The Clock framework allows users to specify a callback which is called after the clock's period has been updated. Some users need to also have a callback which is called before the clock period is updated. As the first step in adding support for notifying Clock users on pre-update events, add an argument to the ClockCallback to specify what event is being notified, and add an argument to the various functions for registering a callback to specify which events are of interest to that callback. Note that the documentation update renders correct the previously incorrect claim in 'Adding a new clock' that callbacks "will be explained in a following section".

we cannot in principle make the TCG Operations field definitions conditional on CONFIG_TCG in code that is included by both common_ss and specific_ss modules. Therefore, what we can do safely to restrict the TCG fields to TCG-only builds, is to move all tcg cpu operations into a separate header file, which is only included by TCG, target-specific code. This leaves just a NULL pointer in the cpu.h for the non-TCG builds. This also tidies up the code in all targets a bit, having all TCG cpu operations neatly contained by a dedicated data struct.

2021-01-04hw/mips: Add Loongson-3 machine supportHuacai Chen
Add Loongson-3 based machine support, it use liointc as the interrupt controler and use GPEX as the pci controller. Currently it can work with both TCG and KVM. As the machine model is not based on any exiting physical hardware, the name of the machine is "loongson3-virt". It may be superseded in future by a real machine model. If this happens, then a regular deprecation procedure shall occur for "loongson3-virt" machine. We now already have a full functional Linux kernel (based on Linux-5.4.x LTS) here: https://github.com/chenhuacai/linux Of course the upstream kernel is also usable (the kvm host side and guest side have both been upstream in Linux-5.9): https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git How to use QEMU/Loongson-3? 1, Download kernel source from the above URL; 2, Build a kernel with arch/mips/configs/loongson3_defconfig; 3, Boot a Loongson-3A4000 host with this kernel (for KVM mode); 4, Build QEMU-master with this patchset; 5, modprobe kvm (only necessary for KVM mode); 6, Use QEMU with TCG: qemu-system-mips64el -M loongson3-virt,accel=tcg -cpu Loongson-3A1000 -kernel <path_to_kernel> -append ... Use QEMU with KVM: qemu-system-mips64el -M loongson3-virt,accel=kvm -cpu Loongson-3A4000 -kernel <path_to_kernel> -append ... The "-cpu" parameter is optional here and QEMU will use the correct type for TCG/KVM automatically.
