2141 7037 d 6 h jermar /trunk/ The Ultimate Solution To Illegal Virtual Aliases.
It is better to avoid them completely than to fight them.
Switch the sparc64 port to 16K pages. The TLBs and TSBs
continue to operate with 8K pages only. Page tables and
other generic parts operate with 16K pages.

Because the MMU doesn't support 16K directly, each 16K
page is emulated by a pair of 8K pages. With 16K pages,
illegal aliases cannot be created in 16K D-cache.
 
2071 7106 d 9 h jermar /trunk/ (c) versus (C)  
2048 7138 d 11 h jermar /trunk/ Formatting and indentation changes.  
2015 7145 d 10 h jermar /trunk/ Rework support for virtually indexed cache.
Instead of repeatedly flushing the data cache, which was a huge overkill, refuse to create an illegal address alias
in the kernel (again) and allocate appropriate page color in userspace instead. Extend the detection also to
SYS_PHYSMEM_MAP syscall.

Add support for tracking physical memory areas mappable by SYS_PHYSMEM_MAP.

Lots of coding style changes.
 
1982 7166 d 17 h jermar /trunk/ Modify the sparc64 startup code to not cause MMU traps before it takes over the TLB and
the trap table. Fix several PA2KA and KA2PA omittions or errors. Fix configuration to pass
the DEFS variable along.
 
1918 7206 d 9 h jermar /trunk/kernel/arch/sparc64/src/mm/ Omitted comma.  
1917 7206 d 10 h jermar /trunk/ sparc64 work:
- hw_map() can now support up to 8M requests
- CPU stacks are now locked in DTLB of the respective processor
- kernel in the boot phase no longer relies on the stack provided by OpenFirmware
- instead of of doing FLUSHW during kernel startup, simply set the
window state registers to the wanted state
- NWINDOW -> NWINDOWS
- Add/fix some comments and copyrights.
 
1903 7218 d 10 h jermar /trunk/ SMP stuff for sparc64.
Almost complete except for IPIs.
The absence of IPI support deadlocks
the kernel when more CPUs are configured.
 
1888 7231 d 13 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1841 7267 d 18 h jermar /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.
 
1793 7293 d 18 h jermar /trunk/kernel/ Change hw_map() on sparc64 to use virtual addresses that are
beyond the end of physical memory. It is beneficial in two
ways: first, physical memory is no longer being wasted by
otherwise necessary calls to frame_alloc() and, second,
virtual addresses for devices are now correctly allocated
and do not overlap with the 4M TLB-locked mapping for
kernel text and data.
 
1787 7296 d 12 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 7303 d 13 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1770 7304 d 14 h jermar /kernel/trunk/arch/sparc64/src/mm/ Fix sparc64 to compile again.  
1760 7314 d 14 h palkovsky /kernel/trunk/ Changed interface of frame_alloc/free to use address of frame instead of the pfn.
This makes it impossible to use >4GB of memory on 32-bit machines, but who cares...
 
1702 7324 d 15 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1410 7344 d 16 h jermar /kernel/trunk/arch/sparc64/ Modify sparc64 to choose optimal page size in each invocation of hw_map().
Use hw_map() to map keyboard device memory.
 
1382 7348 d 9 h decky /kernel/trunk/ make hardware memory mapping more generic  
793 7451 d 15 h jermar /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.
 
684 7480 d 15 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.
 
534 7515 d 10 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 7515 d 10 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 7527 d 15 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
426 7550 d 16 h jermar /SPARTAN/trunk/ sparc64 work.
Add context_save(), context_set() and context_restore().
Remove putchar() definition from ofw.c.
Add sparc64 putchar().
Add ppc32 putchar() (i.e. the original ofw.c putchar()).
Make arg.h use the builtin va_* constructs.
