* i386: hvf: Don't duplicate register resetRoman Bolshakov2020-07-111-1/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | hvf_reset_vcpu() duplicates actions performed by x86_cpu_reset(). The difference is that hvf_reset_vcpu() stores initial values directly to VMCS while x86_cpu_reset() stores it in CPUX86State and then cpu_synchronize_all_post_init() or cpu_synchronize_all_post_reset() flushes CPUX86State into VMCS. That makes hvf_reset_vcpu() a kind of no-op. Here's the trace of CPU state modifications during VM start: hvf_reset_vcpu (resets VMCS) cpu_synchronize_all_post_init (overwrites VMCS fields written by hvf_reset_vcpu()) cpu_synchronize_all_states hvf_reset_vcpu (resets VMCS) cpu_synchronize_all_post_reset (overwrites VMCS fields written by hvf_reset_vcpu()) General purpose registers, system registers, segment descriptors, flags and IP are set by hvf_put_segments() in post-init and post-reset, therefore it's safe to remove them from hvf_reset_vcpu(). PDPTE initialization can be dropped because Intel SDM (26.3.1.6 Checks on Guest Page-Directory-Pointer-Table Entries) doesn't require PDPTE to be clear unless PAE is used: "A VM entry to a guest that does not use PAE paging does not check the validity of any PDPTEs." And if PAE is used, PDPTE's are initialized from CR3 in macvm_set_cr0().

| | | | | | | | | | | | "sysemu/hvf.h" is intended for inclusion in generic code. However it also contains several hvf definitions and declarations, including HVFState that are used only inside "hvf.c".

* Include hw/hw.h exactly where neededMarkus Armbruster2019-08-161-1/+0Star
| | | | | | | | | | | | | | | | In my "build everything" tree, changing hw/hw.h triggers a recompile of some 2600 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). The previous commits have left only the declaration of hw_error() in hw/hw.h. This permits dropping most of its inclusions. Touching it now recompiles less than 200 objects.

* include: Make headers more self-containedMarkus Armbruster2019-08-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Back in 2016, we discussed[1] rules for headers, and these were generally liked: 1. Have a carefully curated header that's included everywhere first. We got that already thanks to Peter: osdep.h. 2. Headers should normally include everything they need beyond osdep.h. If exceptions are needed for some reason, they must be documented in the header. If all that's needed from a header is typedefs, put those into qemu/typedefs.h instead of including the header. 3. Cyclic inclusion is forbidden. This patch gets include/ closer to obeying 2. It's actually extracted from my "[RFC] Baby steps towards saner headers" series[2], which demonstrates a possible path towards checking 2 automatically. It passes the RFC test there.

* i386: hvf: add code base from Google's QEMU repositorySergio Andres Gomez Del Real2017-12-221-0/+102
This file begins tracking the files that will be the code base for HVF support in QEMU. This code base is part of Google's QEMU version of their Android emulator, and can be found at https://android.googlesource.com/platform/external/qemu/+/emu-master-dev This code is based on Veertu Inc's vdhh (Veertu Desktop Hosted Hypervisor), found at https://github.com/veertuinc/vdhh. Everything is appropriately licensed under GPL v2-or-later, except for the code inside x86_task.c and x86_task.h, which, deriving from KVM (the Linux kernel), is licensed GPL v2-only. This code base already implements a very great deal of functionality, although Google's version removed from Vertuu's the support for APIC page and hyperv-related stuff. According to the Android Emulator Release Notes, Revision 26.1.3 (August 2017), "Hypervisor.framework is now enabled by default on macOS for 32-bit x86 images to improve performance and macOS compatibility", although we better use with caution for, as the same Revision warns us, "If you experience issues with it specifically, please file a bug report...". The code hasn't seen much update in the last 5 months, so I think that we can further develop the code with occasional visiting Google's repository to see if there has been any update. On top of Google's code, the following changes were made: - add code to the configure script to support the --enable-hvf argument. If the OS is Darwin, it checks for presence of HVF in the system. The patch also adds strings related to HVF in the file qemu-options.hx. QEMU will only support the modern syntax style '-M accel=hvf' no enable hvf; the legacy '-enable-hvf' will not be supported. - fix styling issues - add glue code to cpus.c - move HVFX86EmulatorState field to CPUX86State, changing the the emulation functions to have a parameter with signature 'CPUX86State *' instead of 'CPUState *' so we don't have to get the 'env'.
