ia64 work.
Comment some offending steps of heavyweight interrupt handler regarding RSE switching.
With this change, ia64 will do well on tests rwlock #4 and thread #1.
Cleanup. |

Changes in build system.
For .S targets, always do -D__ASM__.
Remove unnecessary #define __ASM__ from various *.S files.
At the end of build, generate disassembler dump for kernel.raw.
ia64 work.
Better General Exception handler. |

ia64 work.
Big cleanup of IA-64 interrupt processing.
Merge of interrupt.c and interrupt_handler.c.
Rewrite of ivt.S and interrupt.c.
Higher level interrupt handlers are now passed a vector number and a pointer to stack structure.
ia32 work.
ia32 has ordered writes. Until it deploys weaker memory ordering model, write_barrier() can be empty statement. |

Do not break memory stack alignment in heavyweight interrupt handler.
Reserve scratch area for nested procedure calls on memory stack. |

IA-64 work.
Put RSE into lazy mode before writing ar.bspstore and ar.rnat.

Make context_set() reset ar.pfs.pfm (especially ar.pfs.pfm.sol) so that register stack does not underflow. |
|

Create generic context_save() and context_restore().
These two functions are defined inline and only call context_save_arch() and context_restore_arch(), respectively.
The main purpose of this is to enable centralized commenting of these important and tricky functions. |
|

6839 d 10 h |
jermar |
/SPARTAN/trunk/ |
Rename cpu_priority_{high|low|restore|read} functions to interrupts_{disable|enable|restore|read}.
Rename pri_t to ipl_t (Interrupt Priority Level).
Rename thread_t::pri to thread_t::priority. |

IA-64 work.
context_save() doesn't have to restore ar.pfs as it is a leaf procedure.
Get rid of assembler warning for start.S. |

Updated symtab so that it works correctly with BE architectures.
Changed compiler for BE MIPS to be mips-sgi-irix5, because
mipsel -EB does not behave correctly.
Doc updates to amd64.
Added ARC BIOS support to MIPS architecture. Putchar works correctly,
kernel passed FPU & some rwlock tests. |

Cleanup of makefiles to have common options in one main makefile.
Add simple build process for different simulators for MIPS.
Added FPU context & lazy FPU context switching to MIPS.
Cleanup of MIPS linker script.
Moved MIPS kernel above 1MB. Not tested on real machine yet, but it might help.
There is something broken with gcc inlined memcpy (either simulator or gcc), it is disabled on BigEndian mips now. |
