2015-11-06hw/display/tcx: Remove superfluous OBJECT() typecastsThomas Huth
The tcx_initfn() function is already supplied with an Object *obj pointer, so there is no need to cast the state pointer back to an Object pointer all over the place. And while we're at it, also remove the superfluous "return;" statement in this function.

2015-10-09hw: do not pass NULL to memory_region_init from instance_initPaolo Bonzini
This causes the region to outlive the object, because it attaches the region to /machine. This is not nice for the "realize" method, but much worse for "instance_init" because it can cause dangling pointers after a simple object_new/object_unref pair.

2015-09-18Fix bad error handling after memory_region_init_ram()Markus Armbruster
Symptom: $ qemu-system-x86_64 -m 10000000 Unexpected error in ram_block_add() at /work/armbru/qemu/exec.c:1456: upstream-qemu: cannot set up guest memory 'pc.ram': Cannot allocate memory Aborted (core dumped) Root cause: commit ef701d7 screwed up handling of out-of-memory conditions. 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.

After previous Peter patch, they are redundant. This way we don't assign them except when needed. Once there, there were lots of case where the ".fields" indentation was wrong: .fields = (VMStateField []) { and .fields = (VMStateField []) { Change all the combinations to: .fields = (VMStateField[]){ The biggest problem (appart from aesthetics) was that checkpatch complained when we copy&pasted the code from one place to another.

2013-11-21sun4m: Add FCode ROM for TCX framebufferMark Cave-Ayland
Upstream OpenBIOS now implements SBus probing in order to determine the contents of a physical bus slot, which is required to allow OpenBIOS to identify the framebuffer without help from the fw_cfg interface. SBus probing works by detecting the presence of an FCode program (effectively tokenised Forth) at the base address of each slot, and if present executes it so that it creates its own device node in the OpenBIOS device tree. The FCode ROM is generated as part of the OpenBIOS build and should generally be updated at the same time.

2013-04-20qdev: Drop taddr propertiesPeter Maydell
Drop all the infrastructure for taddr properties (ie ones which are 'hwaddr' sized). These are now unused, and any further desired use would be rather questionable since device properties shouldn't generally depend on a type that is conceptually variable based on the target CPU. 32 or 64 bit integer properties should be used instead as appropriate for the specific device.

2013-04-16console: simplify screendumpGerd Hoffmann
Screendumps are alot simpler as we can update non-active QemuConsoles now. So we only need to update the QemuConsole we want write out, then dump the DisplaySurface content into a ppm file. Done. No console switching needed. No special support code in the gfx card emulation needed. Zap it all. Also move ppm_save out of the vga code and next to the qmp_screendump function. For now screen dumping is limited to console #0 (like it used to be), even though it is dead simple to extend it to other consoles. I wanna finish the console cleanup before setting new qapi interfaces into stone. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Tested-by: Igor Mitsyanko <i.mitsyanko@gmail.com>
