2019-11-05q800: fix I/O memory mapLaurent Vivier
Linux kernel 5.4 will introduce a new memory map for SWIM device. (aee6bff1c325 ("m68k: mac: Revisit floppy disc controller base addresses")) Until this release all MMIO are mapped between 0x50f00000 and 0x50f40000, but it appears that for real hardware 0x50f00000 is not the base address: the MMIO region spans 0x50000000 through 0x60000000, and 0x50040000 through 0x54000000 is repeated images of 0x50000000 to 0x50040000.

2019-10-28hw/m68k: define Macintosh Quadra 800Laurent Vivier
If you want to test the machine, it doesn't yet boot a MacROM, but you can boot a linux kernel from the command line. You can install your own disk using debian-installer with: ./qemu-system-m68k \ -M q800 \ -serial none -serial mon:stdio \ -m 1000M -drive file=m68k.qcow2,format=qcow2 \ -net nic,model=dp83932,addr=09:00:07:12:34:57 \ -append "console=ttyS0 vga=off" \ -kernel vmlinux-4.15.0-2-m68k \ -initrd initrd.gz \ -drive file=debian-9.0-m68k-NETINST-1.iso \ -drive file=m68k.qcow2,format=qcow2 \ -nographic If you use a graphic adapter instead of "-nographic", you can use "-g" to set the size of the display (I use "-g 1600x800x24").

2019-10-28hw/m68k: add a dummy SWIM floppy controllerLaurent Vivier
SWIM (Sander-Wozniak Integrated Machine) is the floppy controller of the 680x0 Macintosh. This patch introduces only the basic support: it allows to switch from IWM (Integrated WOZ Machine) mode to the SWIM mode and makes the linux driver happy. It cannot read any floppy image.

2019-10-15ptimer: Rename ptimer_init() to ptimer_init_with_bh()Peter Maydell
Currently the ptimer design uses a QEMU bottom-half as its mechanism for calling back into the device model using the ptimer when the timer has expired. Unfortunately this design is fatally flawed, because it means that there is a lag between the ptimer updating its own state and the device callback function updating device state, and guest accesses to device registers between the two can return inconsistent device state. We want to replace the bottom-half design with one where the guest device's callback is called either immediately (when the ptimer triggers by timeout) or when the device model code closes a transaction-begin/end section (when the ptimer triggers because the device model changed the ptimer's count value or other state). As the first step, rename ptimer_init() to ptimer_init_with_bh(), to free up the ptimer_init() name for the new API. We can then convert all the ptimer users away from ptimer_init_with_bh() before removing it entirely. (Commit created with git grep -l ptimer_init | xargs sed -i -e 's/ptimer_init/ptimer_init_with_bh/' and three overlong lines folded by hand.)

2019-10-01hw/m68k/next-cube: Avoid static RTC variables and introduce control registerThomas Huth
Coverity currently complains that the "if (0x00 & (0x80 >> (phase - 8))" in next-cube.c can never be true. Right it is. The "0x00" is meant as value of the control register of the RTC, which is currently not implemented yet. Thus, let's add a register variable for this now. However, the RTC registers are currently defined as static variables in nextscr2_write(), which is quite ugly. Thus let's also move the RTC variables to the main machine state instead. In the long run, we should likely even refactor the whole RTC code into a separate device in a separate file, but that's something for calm winter nights later... as a first step, cleaning up the static variables and shutting up the warning from Coverity should be sufficient.

2019-02-05elf: Add optional function ptr to load_elf() to parse ELF notesLiam Merwick
This patch adds an optional function pointer, 'elf_note_fn', to load_elf() which causes load_elf() to additionally parse any ELF program headers of type PT_NOTE and check to see if the ELF Note is of the type specified by the 'translate_opaque' arg. If a matching ELF Note is found then the specfied function pointer is called to process the ELF note. Passing a NULL function pointer results in ELF Notes being skipped. The first consumer of this functionality is the PVHboot support which needs to read the XEN_ELFNOTE_PHYS32_ENTRY ELF Note while loading the uncompressed kernel binary in order to discover the boot entry address for the x86/HVM direct boot ABI.

2017-09-19cpu: make cpu_generic_init() abort QEMU on errorIgor Mammedov
Almost every user of cpu_generic_init() checks for returned NULL and then reports failure in a custom way and aborts process. Some users assume that call can't fail and don't check for failure, though they should have checked for it. In either cases cpu_generic_init() failure is fatal, so instead of checking for failure and reporting it various ways, make cpu_generic_init() report errors in consistent way and terminate QEMU on failure.

2016-10-08m68k: change default system clock for m5208evbGreg Ungerer
The shipping default setting for the Freescale M5208EVB board is to run the CPU at 166.67MHz. The current qemu emulation code for this board is defaulting to 66MHz. This results in time appearing to run way to slowly. So a "sleep 5" in a standard ColdFire Linux build takes almost 15 seconds in real time to actually complete. Change the hard coded default to match the default hardware setting.

2016-03-22include/qemu/osdep.h: Don't include qapi/error.hMarkus Armbruster
Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the Error typedef. Since then, we've moved to include qemu/osdep.h everywhere. Its file comment explains: "To avoid getting into possible circular include dependencies, this file should not include any other QEMU headers, with the exceptions of config-host.h, compiler.h, os-posix.h and os-win32.h, all of which are doing a similar job to this file and are under similar constraints." qapi/error.h doesn't do a similar job, and it doesn't adhere to similar constraints: it includes qapi-types.h. That's in excess of 100KiB of crap most .c files don't actually need. Add the typedef to qemu/typedefs.h, and include that instead of qapi/error.h. Include qapi/error.h in .c files that need it and don't get it now. Include qapi-types.h in qom/object.h for uint16List. Update scripts/clean-includes accordingly. Update it further to match reality: replace config.h by config-target.h, add sysemu/os-posix.h, sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h comment quoted above similarly. This reduces the number of objects depending on qapi/error.h from "all of them" to less than a third. Unfortunately, the number depending on qapi-types.h shrinks only a little. More work is needed for that one. Signed-off-by: Markus Armbruster <armbru@redhat.com> [Fix compilation without the spice devel packages. - Paolo] Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2016-03-04loader: Add data swap option to load-elfPeter Crosthwaite
Some CPUs are of an opposite data-endianness to other components in the system. Sometimes elfs have the data sections layed out with this CPU data-endianness accounting for when loaded via the CPU, so byte swaps (relative to other system components) will occur. The leading example, is ARM's BE32 mode, which is is basically LE with address manipulation on half-word and byte accesses to access the hw/byte reversed address. This means that word data is invariant across LE and BE32. This also means that instructions are still LE. The expectation is that the elf will be loaded via the CPU in this endianness scheme, which means the data in the elf is reversed at compile time. As QEMU loads via the system memory directly, rather than the CPU, we need a mechanism to reverse elf data endianness to implement this possibility.

Replace hw_error() by error_report(); exit(1). Matches how we report these errors in other machine initializations.
