Modify framebuffer and NGA framebuffer to read screen size from board model dtb file. Optimise memory usuage of frame buffer
Add example minigui application with hooks to profiler (which writes results to S:\). Modified NGA framebuffer to run its own dfc queue at high priority
Correctness issues:
- some eflags manipulation incorrectly reset the bit 0x2.
- SVM: test, cpu save/restore, SMM save/restore.
- x86_64: lcall/ljmp intel/amd differences ?
- better code fetch (different exception handling + CS.limit support)
- user/kernel PUSHL/POPL in helper.c
- add missing cpuid tests
- return UD exception if LOCK prefix incorrectly used
- test ldt limit < 7 ?
- fix some 16 bit sp push/pop overflow (pusha/popa, lcall lret)
- full support of segment limit/rights
- full x87 exception support
- improve x87 bit exactness (use bochs code ?)
- DRx register support
- CR0.AC emulation
- SSE alignment checks
- fix SSE min/max with nans
Optimizations/Features:
- add SVM nested paging support
- add VMX support
- add AVX support
- add SSE5 support
- fxsave/fxrstor AMD extensions
- improve monitor/mwait support
- faster EFLAGS update: consider SZAP, C, O can be updated separately
with a bit field in CC_OP and more state variables.
- evaluate x87 stack pointer statically
- find a way to avoid translating several time the same TB if CR0.TS
is set or not.
- move kqemu support outside target-i386.
