This keeps compatibility on machine-types pc-1.2 and older, and prints a warning in case the requested configuration won't get the correct topology. I couldn't think of a better way to warn about broken topology when in compat mode other than using error_report(). The warning message will probably be buried in a log file somewhere, but it's better than nothing.

This introduces utility functions for the APIC ID calculation, based on: Intel® 64 Architecture Processor Topology Enumeration http://software.intel.com/en-us/articles/intel-64-architecture-processor-topology-enumeration/ The code should be compatible with AMD's "Extended Method" described at: AMD CPUID Specification (Publication #25481) Section 3: Multiple Core Calcuation as long as: - nr_threads is set to 1; - OFFSET_IDX is assumed to be 0; - CPUID Fn8000_0008_ECX[ApicIdCoreIdSize[3:0]] is set to apicid_core_width().

The CPU ID in KVM is supposed to be the APIC ID, so change the KVM_CREATE_VCPU call to match it. The current behavior didn't break anything yet because today the APIC ID is assumed to be equal to the CPU index, but this won't be true in the future.

Currently, the pc-1.4 machine init function enables PV EOI and then calls the pc-1.2 machine init function. The problem with this approach is that now we can't enable any additional compatibility code inside the pc-1.2 init function because it would end up enabling the compatibility behavior on pc-1.3 and pc-1.4 as well. This reverses the logic so that the pc-1.2 machine init function will disable PV EOI, and then call the pc-1.4 machine init function. This way we can change older machine-types to enable compatibility behavior, and the newer machine-types (pc-1.3, pc-q35-1.4 and pc-i440fx-1.4) would just use the default behavior. (This means that one nice side-effect of this change is that pc-q35-1.4 will get PV EOI enabled by default, too) It would be interesting to eventually change pc_init_pci_no_kvmclock() and pc_init_isa() to reuse pc_init_pci_1_2() as well (so we don't need to duplicate compatibility code on those two functions). But this will be probably much easier to do after we create a PCInitArgs struct for the PC initialization arguments, and/or after we use global-properties to implement the compatibility modes present in pc_init_pci_1_2().

This is a cleanup that tries to solve two small issues: - We don't need a separate kvm_pv_eoi_features variable just to keep a constant calculated at compile-time, and this style would require adding a separate variable (that's declared twice because of the CONFIG_KVM ifdef) for each feature that's going to be enabled/disabled by machine-type compat code. - The pc-1.3 code is setting the kvm_pv_eoi flag on cpuid_kvm_features even when KVM is disabled at runtime. This small inconsistency in the cpuid_kvm_features field isn't a problem today because cpuid_kvm_features is ignored by the TCG code, but it may cause unexpected problems later when refactoring the CPUID handling code. This patch eliminates the kvm_pv_eoi_features variable and simply uses kvm_enabled() inside the enable_kvm_pv_eoi() compat function, so it enables kvm_pv_eoi only if KVM is enabled. I believe this makes the behavior of enable_kvm_pv_eoi() clearer and easier to understand.

This is a follow up for several attempts to fix this issue. Previous incarnations: 1. http://thread.gmane.org/gmane.linux.ubuntu.bugs.general/3156089 https://bugs.launchpad.net/bugs/918791 "qemu-kvm dies when using vmvga driver and unity in the guest" bug. Fix by Serge Hallyn: https://launchpadlibrarian.net/94916786/qemu-vmware.debdiff This fix is incomplete, since it does not check width and height for being negative. Serge weren't sure if that's the right place to fix it, maybe the fix should be up the stack somewhere. 2. http://thread.gmane.org/gmane.comp.emulators.qemu/166064 by Marek Vasut: "vmware_vga: Redraw only visible area" This one adds the (incomplete) check to vmsvga_update_rect_delayed(), the routine just queues the rect updating but does no interesting stuff. It is also incomplete in the same way as patch by Serge, but also does not touch width&height at all after adjusting x&y, which is wrong. As far as I can see, when processing guest requests, the device places them into a queue (vmsvga_update_rect_delayed()) and processes this queue in different place/time, namely, in vmsvga_update_rect(). Sometimes, vmsvga_update_rect() is called directly, without placing the request to the gueue. This is the place this patch changes, which is the last (deepest) in the stack. I'm not sure if this is the right place still, since it is possible we have some queue optimization (or may have in the future) which will be upset by negative/wrong values here, so maybe we should check for validity of input right when receiving request from the guest (and maybe even use unsigned types there). But I don't know the protocol and implementation enough to have a definitive answer. But since vmsvga_update_rect() has other sanity checks already, I'm adding the missing ones there as well. Cc'ing BALATON Zoltan and Andrzej Zaborowski who shows in `git blame' output and may know something in this area. If this patch is accepted, it should be applied to all active stable branches (at least since 1.1, maybe even before), with minor context change (ds_get_*(s->vga.ds) => s->*). I'm not Cc'ing -stable yet, will do it explicitly once the patch is accepted. BTW, these checks use fprintf(stderr) -- it should be converted to something more appropriate, since stderr will most likely disappear somewhere.

Align the device tree blob to a 4KB boundary, not to QEMU's idea of a page boundary -- the latter is the smallest possible page size for the architecture, which on ARM is 1KB. The documentation for Linux does not impose separation or alignment requirements on the device tree blob, but in practice some kernels will happily trash the entire page the initrd ends in after they have finished uncompressing the initrd.

read_splashfile() passes the address of an int variable as size_t * parameter to g_file_get_contents(), with a cast to gag the compiler. No problem on machines where sizeof(size_t) == sizeof(int). Happens to work on my x86_64 box (64 bit little endian): the least significant 32 bits of the file size end up in the right place (caller's variable file_size), and the most significant 32 bits clobber a place that gets assigned to before its next use (caller's variable file_type). I'd expect it to break on a 64 bit big-endian box. Fix up the variable types and drop the problematic cast.
