| * mac_newworld: always enable disable_direct_reg3_writes for ADB machinesMark Cave-Ayland2018-07-031-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Commit 84051eb400 "adb: add property to disable direct reg 3 writes" added a workaround for MacOS 9 incorrectly setting the mouse address during boot of PMU machines. Further testing has shown that since fb6649f172 "adb: fix read reg 3 byte ordering" this can still sometimes happen with the CUDA mac99 machine, so let's enable this workaround for all New World machines using ADB for now.

* mac_newworld: add via machine option to control mac99 VIA/ADB configurationMark Cave-Ayland2018-06-161-7/+62
| | | | | | | | | | | | | | | | This option allows the VIA configuration to be controlled between 3 different possible setups: cuda, pmu-adb and pmu with USB rather than ADB keyboard/mouse. For the moment we don't do anything with the configuration except to pass it to the macio device (the via-cuda parent) and also to the firmware via the fw_cfg interface so that it can present the correct device tree. The default is cuda which is the current default and so will have no change in behaviour.

* hw: Default -drive to if=ide explicitly where it worksMarkus Armbruster2017-02-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Block backends defined with -drive if=ide are meant to be picked up by machine initialization code: a suitable frontend gets created and wired up automatically. if=ide drives not picked up that way can still be used with -device as if they had if=none, but that's unclean and best avoided. Unused ones produce an "Orphaned drive without device" warning. -drive parameter "if" is optional, and the default depends on the machine type. If a machine type doesn't specify a default, the default is "ide". Many machine types default to if=ide, even though they don't actually have an IDE controller. A future patch will change these defaults to something more sensible. To prepare for it, this patch makes default "ide" explicit for the machines that actually pick up if=ide drives: * alpha: clipper * arm/aarch64: spitz borzoi terrier tosa * i386/x86_64: generic-pc-machine (with concrete subtypes pc-q35-* pc-i440fx-* pc-* isapc xenfv) * mips64el: fulong2e * mips/mipsel/mips64el: malta mips * ppc/ppc64: mac99 g3beige prep * sh4/sh4eb: r2d * sparc64: sun4u sun4v Note that ppc64 machine powernv already sets an "ide" default explicitly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* loader: Add data swap option to load-elfPeter Crosthwaite2016-03-041-2/+3
| | | | | | | | | | | | | | | | | | | | | | | 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.

* hw: Don't use hw_error() for machine initialization errorsMarkus Armbruster2016-01-131-5/+6
| | | | | | | | | | | | | | | | | | Printing CPU registers is not helpful during machine initialization. Moreover, these are straightforward configuration or "can get resources" errors, so dumping core isn't appropriate either. Replace hw_error() by error_report(); exit(1). Matches how we report these errors in other machine initializations.

* PPC: mac99: Always add USB controllerAlexander Graf2015-11-121-1/+2
| | | | | | | | | | | | | The mac99 machines always have a USB controller. Usually not having one around doesn't hurt quite as much, but Mac OS 9 really really wants one or it crashes on bootup. So always add OHCI to make it happy.

So instead of requiring each subclass to set MachineClass::name manually, we can now set it automatically at the TYPE_MACHINE class_base_init() function.

* Fix bad error handling after memory_region_init_ram()Markus Armbruster2015-09-181-1/+1

Before the commit, we report the error and exit(1), in one place, ram_block_add(). The commit lifts the error handling up the call chain some, to three places. Fine. Except it uses &error_abort in these places, changing the behavior from exit(1) to abort(), and thus undoing the work of commit 3922825 "exec: Don't abort when we can't allocate guest memory". The three places are: * memory_region_init_ram() Commit 4994653 (right after commit ef701d7) lifted the error handling further, through memory_region_init_ram(), multiplying the incorrect use of &error_abort. Later on, imitation of existing (bad) code may have created more. * memory_region_init_ram_ptr() The &error_abort is still there. * memory_region_init_rom_device() Doesn't need fixing, because commit 33e0eb5 (soon after commit ef701d7) lifted the error handling further, and in the process changed it from &error_abort to passing it up the call chain. Correct, because the callers are realize() methods. Fix the error handling after memory_region_init_ram() with a Coccinelle semantic patch: @r@ expression mr, owner, name, size, err; position p; @@ memory_region_init_ram(mr, owner, name, size, ( - &error_abort + &error_fatal | err@p ) ); @script:python@ p << r.p; @@ print "%s:%s:%s" % (p[0].file, p[0].line, p[0].column) When the last argument is &error_abort, it gets replaced by &error_fatal. This is the fix. If the last argument is anything else, its position is reported. This lets us check the fix is complete. Four positions get reported: * ram_backend_memory_alloc() Error is passed up the call chain, ultimately through user_creatable_complete(). As far as I can tell, it's callers all handle the error sanely. * fsl_imx25_realize(), fsl_imx31_realize(), dp8393x_realize() DeviceClass.realize() methods, errors handled sanely further up the call chain. We're good. Test case again behaves: $ qemu-system-x86_64 -m 10000000 qemu-system-x86_64: cannot set up guest memory 'pc.ram': Cannot allocate memory [Exit 1 ] The next commits will repair the rest of commit ef701d7's damage.
