Correct sleeping on memory allocation during FPU lazy switch. |
|
| 906 |
6677 d 20 h |
palkovsky |
/kernel/trunk/ |
Added lazy fpu context allocation.
- threads that don't use fpu, don't get allocated fpu context
- fpu context alignment on AMD64 nicely disappeared |

sparc64 work.
Fix KBD_VIRT_ADDRESS.
Call before_thread_runs() prior to the switch to the thread's stack. Add comment why this is crucial.
Add after_thread_ran() to the scheduler.
Add before_thread_runs_arch() and after_thread_ran_arch() for sparc64, mapping/demapping thread's kernel stack.
Add dummy after_thread_ran_arch() to all other architectures.
Add dtlb_insert_mapping() to promote code reuse. |

Avoid memory exhaustion in thread_create in slab2 test. |
|
| 827 |

Unimportant changes regarding FPU context. |
|

Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization. |
|

Changed malloc to include second parameter and documented
recommended usage.
Added zone merging, made ia32 & amd64 to merge found zones. |

Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print. |

frame_alloc() functions variations in order to avoid problems with frame_alloc_generic() changes.
IMPORTANT: Parameter order for frame_alloc() was changed |
|

Cleanup of scheduler code |

Fixed some typos in slab allocator.
Scheduler now has better algorithm on load balancing.
Unfortunately it reveals deadlock in slab allocator :-/ |
|
| 779 |
6703 d 23 h |
jermar |
/kernel/trunk/generic/ |
Simplify load balancing activation.
This in fact removes the livelock that prevented cpu_sleep() to be called in SMP systems. |
|
| 777 |
6704 d 2 h |
palkovsky |
/kernel/trunk/generic/ |
added thread list to kconsole. |
|
| 775 |
6704 d 6 h |
palkovsky |
/kernel/trunk/generic/ |
Added scheduler queues output. The scheduler is buggy - on SMP
the cpus never get tu cpu_sleep, in slab2 test on 4 cpus everything
is on the first cpu.
The slab allocator passes tests in this configuration, but in slightly
different(more efficient) locking order it panics. TODO: Find out why
does it panic. |

Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference |
|

6726 d 7 h |

/kernel/trunk/ |
Memory management work.
- vm.* -> as.* (as like address space is, imho, more fitting)
- Don't do TLB shootdown on vm_install(). Some architectures only need to call tlb_invalidate_asid().
- Don't allocate all frames for as_area in as_area_create(), but let them be allocated on-demand by as_page_fault().
- Add high-level page fault handler as_page_fault().
- Add as_area_load_mapping(). |
