2023-06-22q800: reimplement mac-io region aliasing using IO memory regionMark Cave-Ayland1-19/+81
The current use of aliased memory regions causes us 2 problems: firstly the output of "info qom-tree" is absolutely huge and difficult to read, and secondly we have already reached the internal limit for memory regions as adding any new memory region into the mac-io region causes QEMU to assert with "phys_section_add: Assertion `map->sections_nb < TARGET_PAGE_SIZE' failed". Implement the mac-io region aliasing using a single IO memory region that applies IO_SLICE_MASK representing the maximum size of the aliased region and then forwarding the access to the existing mac-io memory region using the address space API.

2022-10-24m68k: write bootinfo as rom section and re-randomize on rebootJason A. Donenfeld3-59/+111
Rather than poking directly into RAM, add the bootinfo block as a proper ROM, so that it's restored when rebooting the system. This way, if the guest corrupts any of the bootinfo items, but then tries to reboot, it'll still be restored back to normal as expected. Then, since the RNG seed needs to be fresh on each boot, regenerate the RNG seed in the ROM when reseting the CPU.

Following a change on the kernel side (see link), pass BI_RNG_SEED instead of BI_VIRT_RNG_SEED. This should have no impact on compatibility, as there will simply be no effect if it's an old kernel, which is how things have always been. We then use this as an opportunity to add this to q800, since now we can, which is a nice improvement.

2022-07-06m68k: use correct variable name in boot info string macroJason A. Donenfeld1-1/+1
Every time this macro is used, the caller is passing in "parameters_base", so this bug wasn't spotted. But the actual macro variable name is "base", so use that instead. Signed-off-by: Jason A.

2022-05-19ptimer: Rename PTIMER_POLICY_DEFAULT to PTIMER_POLICY_LEGACYPeter Maydell2-2/+2
The traditional ptimer behaviour includes a collection of weird edge case behaviours. In 2016 we improved the ptimer implementation to fix these and generally make the behaviour more flexible, with ptimers opting in to the new behaviour by passing an appropriate set of policy flags to ptimer_init(). For backwards-compatibility, we defined PTIMER_POLICY_DEFAULT (which sets no flags) to give the old weird behaviour. This turns out to be a poor choice of name, because people writing new devices which use ptimers are misled into thinking that the default is probably a sensible choice of flags, when in fact it is almost always not what you want. Rename PTIMER_POLICY_DEFAULT to PTIMER_POLICY_LEGACY and beef up the comment to more clearly say that new devices should not be using it. The code-change part of this commit was produced by sed -i -e 's/PTIMER_POLICY_DEFAULT/PTIMER_POLICY_LEGACY/g' $(git grep -l PTIMER_POLICY_DEFAULT) with the exception of a test name string change in tests/unit/ptimer-test.c which was added manually.

2022-03-21Use g_new() & friends where that makes obvious senseMarkus Armbruster1-1/+1
g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer, for two reasons. One, it catches multiplication overflowing size_t. Two, it returns T * rather than void *, which lets the compiler catch more type errors. This commit only touches allocations with size arguments of the form sizeof(T).

2022-03-09mos6522: implement edge-triggering for CA1/2 and CB1/2 control line IRQsMark Cave-Ayland1-4/+5
The mos6522 datasheet describes how the control lines IRQs are edge-triggered according to the configuration in the PCR register. Implement the logic according to the datasheet so that the interrupt bits in IFR are latched when the edge is detected, and cleared when reading portA/portB or writing to IFR as necessary. To maintain bisectibility this change also updates the SCSI, SCSI data, Nubus and VIA2 60Hz/1Hz clocks in the q800 machine to be negative edge-triggered as confirmed by the PCR programming in all of Linux, NetBSD and MacOS.

"qemu-system-m68k -M q800 -bios /dev/null" crashes with a segfault in q800_init(). This happens because the code doesn't check that rom_ptr() returned a non-NULL pointer . To avoid NULL pointer, don't allow 0 sized file and use bios_size with rom_ptr().
