paging_start counting fix on ia64 |
|

6632 d 10 h |
jermar |
/kernel/trunk/genarch/src/mm/ |
Fix generic page hash table to align down page addresses.
This was the ia64 userspace show stopper. |
|

ia64 work.
Userspace is now working.
There is an unrelated show stopper, however. |
|

/kernel/trunk/ |
ia64 work.
Changes to make userspace work (kernel part).
Use ski.conf from contrib directory to run Ski.
There is actually no appropriate syscall handler yet. |

Support switch from userspace register stack in heavyweight handler. |
|

- Another item had to be allocated on stack to remember new value written to ar.bspstore.
Fix heavyweight interruption handler to calculate RSC.loadrs from the new value of ar.bspstore
instead from the old one.
Uncomment instructions switching ar.bspstore.
- Configure kernel with 512M of memory. |

ivt.S:
Detect userspace stack in heavyweight handler and switch to kernel stack.
Remember the old stack pointer.
As for register stack, kernel stack is assumed still.
Fix alignment issues that showed when STACK_ITEMS was odd.
Fix ld8 instruction that did subtraction of 8 instead of addition of 8.
scheduler.c:
Change before_thread_runs_arch() to calculate address of top of the stack
for the interrupt handler. |

/kernel/trunk/arch/ia64/ |
ia64 work.
Change heavyweight interrupt handler to use bank 0 registers instead of AR.KR0 and AR.KR1.
This prevents userspace from the possibility to see what addresses are being used by kernel.
Store kernel stack address in bank 0 r23 instead of AR.KR7. Again, userspace will not be
able to read the address of its kernel stack.
Increase FRAME_SIZE to 64K as this is the first supported page size in which will fit
thread's combined register and memory stack. (RSE can write out as many as 16K.) |

Correct sleeping on memory allocation during FPU lazy switch. |
|
| 906 |
6639 d 8 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 |
|

/kernel/trunk/ |
Upgrade toolchain build scripts to install binutils 2.16.1 and gcc 4.1.0.
The only exception is ia64, where the kernel does not build with gcc 4.1.0. |

More capable TLB miss handlers.
The ia64 kernel now passes mm/mapping1 test.
Fix generic hash table to properly initialize lists.
Change page_ht() to properly initialize inserted PTE's.
Change format of generic page hash table PTE's. |

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. |

sparc64 work.
Very raw and fragile preliminary standalone keyboard support - polling mode only.
Because of a workaround in Simics, the scan codes are the same as on ia32. |
