3ab94305a0 1. Fixed bug report
[ bochs-Bugs-1562172 ] TLB_init() fails to initialize priv_check array if USE_TLB 0
2. Paging is always exists for i386+
   To disable paging it is better to use normal model without special code, only by setting cr0.pg=0

070d782ec8 Move paddr_valid param of dbg_xlate_linear2phy method to return value.
This is much easier to use.

f8c3968d42 Changes list made after CVS service crash:
- Fixed critical bug in CPU code added with one of the prev commits
  - Disasm support for SSE4
  - Rename PNI->SSE3 everywhere in the code
  - Correctly decode, disassemble and execute 'XCHG R8, rAX' x86-64 instruction
  - Correctly decode, disassemble and execute multi-byte NOP 0F F1 opcode
  - Fixed ENTER and LEAVE instructions in x86-64 mode
  - Added ability to turn ON instruction trace, only GUI support is missed.
    Instruction trace could be enabled if Bochs was compiled with disasm
  - More changes Bit32u -> bx_phy_address
  - Complete preliminary implementation of SMM in Bochs, SMI is still PANICs but if you press 'continue' everything should work OK
  - Small code cleanup
  - Update CHANGES and user docs

7b6c2587a9 Now devices could be compiled separatelly from CPU
Averything that required cpu.h include now has it explicitly and there are a lot of files not dependant by CPU at all which will compile a lot faster now ...

e297df457a Roll back the try to move Local APIC memory access to CPU.

e7e0b40bd1 - remove calculation on cr3 in dtranslate_linear, one of the most called functions (patch by Conn Clark) 2003-12-30 22:12:45 +00:00
Christophe Bothamy
50efc3b8c7 - apply Conn Clark's patch.perf-regparm-cclark :
- it works only on x86 with gcc2.95+
  - uses the GCC function atribute "regparm(n)" to declare that certain
    functions use the register calling convention
  - performance improvement is about 6%

94880d1412 Fix guest2host and related optimizations to work on 64 bit host.
1) fixed the type of "hostPageAddr" and associated typecasts.
2) fixed the type of "pages" and associated typecasts (overloaded variable)
3) patch to cpu.cc to calculate "eipPageBias" correctly in 64 bit mode

cdfc3cbce4 instrumentation enchancements:
* renamed CPU_ID to BX_CPU_ID.
  with this new name there is no possibility for name contentions and BX_CPU_ID
  definition could be moved out to NEED_CPU_REG_SHORTCUTS block

* returned back `unsigned BX_CPU::which_cpu(void)` function

* added BX_CPU_ID parameter for
	BX_INSTR_PHY_READ(a20addr, len);
	BX_INSTR_PHY_WRITE(a20addr, len);
    now it will be
	BX_INSTR_PHY_READ(cpu_id, a20addr, len);
	BX_INSTR_PHY_WRITE(cpu_id, a20addr, len);
