/trunk/kernel/ |
Start reorganization of different keyboard drivers.
What seemed like a screwed i8042 chip appears to be
Zilog 8530.
The repository won't compile now. To be fixed in next commits. |

Add scan code map for Sun keyboard. |
|
| 1837 |
6556 d 19 h |
jermar |
/trunk/ |
Support 24bpp framebuffers with 4 pixelbytes (each pixel aligned on 32-bits).
At least on sparc64, the OpenFirmware linebytes property specifies the number
of pixels between consecutive scan lines of the display. Fix scanilne calculation,
including possible alignment.
Add note to 8bpp pixel functions pointing out drawbacks of that mode. |

Remove OpenFirmware calls from kernel/ entirely.
Switch the sparc64 port to use bootinfo.
Copy memcpy from boot/ to sparc64 kernel/ and
adjust it for memcpy_from/to_uspace. |

Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.). |

Change the way the framebuffer is mapped so that sparc64 is usable again. |
|
| 1371 |
6634 d 6 h |
decky |
/kernel/trunk/ |
unify the framebuffer API
use physical address as the base address for the framebuffer |
|

split framebuffer initialization and sysinfo registration |
|

6639 d 15 h |

/kernel/trunk/ |
Do not report possible deadlock on fb_lock.
This issue was causing troubles in connection
with slow framebuffer in simulated environment
when false positives triggered an infinite
recursion of attempts to report deadlock on
fb_lock using printf() and fb_putchar(). |
|

6666 d 14 h |

Printf ported back from uspace to kernel.
Printf calls changed to match new conventions. |

framebuffer code cleanup, support for non-standard scanline sizes
ppc32: get framebuffer parameters from boot loader |

Small PTE_* macros and SET_PTL0_ADDRESS macro changes. |

ia64 work.
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. |
|

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. |
|

Move i8042 driver to genarch as it might be used by more architectures. |
|
| 867 |
6719 d 13 h |
jermar |
/kernel/trunk/ |
Move OFW functionality of ppc32 memory_init to genarch so that the code can also be used by sparc64.
sparc64 is now close to broken as it lacks functionality to provide identity mapping for the whole phyisical memory. |
|
| 838 |
6727 d 17 h |
palkovsky |
/kernel/trunk/ |
Added untested support for 2 & 4-byte (15-bit & 24-bit depth) framebuffer. |
|
| 837 |

/kernel/trunk/ |
Moved framebuffer to genarch. |
|

6731 d 5 h |

Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3. |
|
| 811 |
6734 d 7 h |

/kernel/trunk/ |
Fix number of steps in softint division.
Make ia64 port compile with softint. |
|
| 810 |
6734 d 12 h |
cejka |
/kernel/trunk/genarch/ |
Added softint for emulation 32 and 64 bit division.
Not tested yet. |
|
| 793 |
6735 d 13 h |

/kernel/trunk/ |
Use hash_table_get_instance instead of list_get_instance.
Rename page_operations to page_mapping_operations.
Rename page_pt_operations to pt_mapping_operations.
Rename page_ht_operations to ht_mapping_operations. |
|
| 792 |
6735 d 13 h |
jermar |
/kernel/trunk/ |
Page hash table architectures now use generic hash table to manage
mappings. |
|
| 760 |
6739 d 15 h |
jermar |
/kernel/trunk/ |
mips32 is not supposed to allocate page table.
This is done by the generic code now.
Remove PTL0 pointer as it is not needed.
Remove GET_PTL0_ADDRESS from kernel.
Update sparc64 comments in barrier.h. |
|
| 756 |
6741 d 4 h |
jermar |
/kernel/trunk/ |
Memory management work.
Remove the last (i.e. 'root') argument from page_mapping_insert() and page_mapping_find().
Page table address is now extracted from the first (i.e. 'as') argument.
Add a lot of infrastructure to make the above possible.
sparc64 is now broken, most likely because of insufficient identity mapping of physical memory. |
|
| 755 |
6742 d 3 h |
jermar |
/kernel/trunk/ |
Change page_mapping_find/insert interfaces to take as_t * as first argument
and not asid_t as second argument. This change was necessitated by the
removal of mapping array from as_area_t and the fact that an address
space doesn't have an ASID when it is created. |

Page hash table modifications. |
|

6751 d 10 h |
jermar |

Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs. |
|

Memory management work.
Proto-interface and dummy implementation of generic page hash table subsytem. |
|
| 684 |
6764 d 13 h |
jermar |
/kernel/trunk/ |
Memory management work.
Move generic 4-level page table interface to genarch
and enable architectures to use different virtual memory
mechanisms (e.g. page hash tables).
Start page hash table support.
Switch ia64 and sparc64 to page hash tables.
Other architectures keep on using 4-level page table interface. |

kconsole support.
Add non-blocking ofw_getchar(). |
