517 6756 d 7 h jermar /kernel/trunk/ Implement basic kernel console command recognition.
Commands without arguments are now recognized.
 
512 6758 d 16 h jermar /kernel/trunk/ SMP work.
Add madt_irq_to_pin().
Make ksmp() use virtual irq_to_pin() function, which makes better sence for ACPI configurations.
 
510 6759 d 6 h jermar /kernel/trunk/ Add chardev_t.
This type is meant to abstract any input character device such as keyboard, serial port etc.
Add stdin.
Add dummy kconsole.
 
506 6759 d 11 h decky /kernel/trunk/ preparation for init task loading  
503 6759 d 13 h jermar /kernel/trunk/ Rename arch_late_init() to arch_pre_smp_init().
Add arch_post_smp_init().
Enable IRQ_KBD on ia-32 (doesn't work on Bochs SMP, works on Bochs UP).
 
501 6759 d 14 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
470 6773 d 4 h jermar /SPARTAN/trunk/ 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.
 
463 6773 d 15 h decky /SPARTAN/trunk/ even fancier release/revision display  
462 6773 d 15 h decky /SPARTAN/trunk/ include svn revision and build time in the kernel  
460 6773 d 17 h decky /SPARTAN/trunk/ some fancy stuff  
458 6773 d 17 h decky /SPARTAN/trunk/ make configuration variables usage consistent  
430 6780 d 7 h jermar /SPARTAN/trunk/ Move src/ and include/ to generic.  
414 6794 d 20 h jermar /SPARTAN/trunk/ 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.
 
413 6795 d 6 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.
 
402 6802 d 18 h jermar /SPARTAN/trunk/ Add ALIGN() macro.

Fix usage of early_mapping() in main.c.
The previous version would not map part of the heap.
Please, review.
 
389 6808 d 18 h jermar /SPARTAN/trunk/ MIPS work.
Fix some name inconsistencies between cp0 functions' declarations and definitions.
Add and implement tlb_init_arch().
Add tlb_modified() exception handler.

Other architectures: add dummy tlb_init_arch().
 
374 6819 d 7 h jermar /SPARTAN/trunk/ Revert previous change in frame_t as it broke IA-64.
(Most likely some alignment problem.)

Rename heap_init(), malloc() and free(), respectively, to early_heap_init(), early_malloc() and early_free(), respectively.
Define new macros malloc() and free(). They are to be replaced by real functions some day.
 
373 6819 d 9 h jermar /SPARTAN/trunk/ Physical memory management work.
Add "__attribute__ ((packed))" to frame_t so that it takes up less space.
Note that this is essential as there is lot of these structures.
Remove busy list from zone_t as it is redundant.
 
369 6821 d 10 h jermar /SPARTAN/trunk/src/main/ The more physical frames, the more memory allocated for heap.  
298 6837 d 17 h decky /SPARTAN/trunk/ remove lower 2 GB identity mapping (IA-32)  
242 6840 d 15 h palkovsky /SPARTAN/trunk/ Fixed stack settings in boot.S in real mode.
Added ia32 memmap support.
Added cpuid support.
 
238 6841 d 12 h vana /SPARTAN/trunk/ Register dump on IA-64 exceptions  
235 6841 d 13 h decky /SPARTAN/trunk/ load the kernel above 1 MB on IA-32  
220 6841 d 21 h vana /SPARTAN/trunk/ Universal exception handler and all exceptions routine to call it added  
212 6842 d 8 h vana /SPARTAN/trunk/ Basic exception support added for ia64 arch ......  
210 6842 d 8 h decky /SPARTAN/trunk/ many PPC stuff, platform dependent arch.h header files  
207 6842 d 18 h decky /SPARTAN/trunk/ separated stack mapping  
192 6843 d 12 h jermar /SPARTAN/trunk/ Dump implementation of THREAD, TASK and CPU.
Implement preemption-safe versions of THREAD, TASK and CPU using THE.
Get rid of CPU_ID_ARCH on all architectures.
Get rid of write_dr0() and read_dr0() on IA-32.
Get rid of cpu_private_data and cpu_private_data_t.
 
184 6843 d 20 h jermar /SPARTAN/trunk/ Add lib/the.c.
Add and deploy the_initialize() and the_copy().

Make IA-32's before_thread_runs() use SP_DELTA macro.
 
180 6844 d 9 h jermar /SPARTAN/trunk/ Globalize 'size' and 'delta' and rename them to 'kernel_size' and 'heap_delta'.

Fix heap initialization to take 'heap_delta' into account.

Implement IA-64 get_stack_base().

Adjust SP_DELTA's to consider one extra word on stack.
(So that the stack pointer is within appropriate limits even on IA-64).

More #include cleanup.
 
177 6844 d 18 h jermar /SPARTAN/trunk/ Add some comments to IA-32 src/boot/boot.S and src/smp.S.

Make the boot stack start on page boundary.
This is required by get_stack_base().

Define 'THE' macro.

Implement preemption_disable() and preemption_enable().

Add memory barrier macros.
IA-32 macros need support for older processors.
Non IA-32 macros are dummy.

Reduction of many #include paths.
 
174 6848 d 8 h jermar /SPARTAN/trunk/ Small changes.
Coding style fix in main.c.
Make 'cli' be the first instruction in boot.S again.
 
167 6854 d 16 h jermar /SPARTAN/trunk/ Switch over to per vm_t page tables. (breaks ia32 userspace)

Define dummy memcopy() for amd64 and ppc to satisfy compiler.

Get rid of problematic #include <arch/mm/page.h> in mm/page.h.

Indentation fixes and small changes here and there.
 
149 6878 d 10 h jermar /SPARTAN/trunk/ Fix IA-32's get_memory_size() to return size of memory in bytes instead of in kilobytes.
Some cosmetics in memory map detection.
The IA-32 kernel is functional again.
 
146 6883 d 15 h cejka /SPARTAN/trunk/ Memory size detection for ia32 completed.  
108 6931 d 14 h decky /SPARTAN/trunk/ doxygen-style comments
NDEBUG in Makefile.config
 
106 6931 d 16 h jermar /SPARTAN/trunk/ IA-32 fixes.
Use kernel addresses instead of physical addresses in map_page_to_frame().
Physical addresses are supposed to only be exported to mm hardware.
Because of this fix, userspace is functional again.

Remap EGA videoram to (0x80000000 + videoram) and change the ega driver to work with the new address.

Minor cosmetics through out the code.
Changes in linker scripts.
 
105 6932 d 6 h jermar /SPARTAN/trunk/ Big changes in IA-32 address space map.
Now the kernel is mapped above 0x80000000. Finally!
Userspace address space starts at 0x00000000.
Changes in many places.
This improvement temporarily breaks SMP and most likely also other stuff.
Supported size of memory is now only 4M as it is the biggest size that can be mapped at once on IA-32.

Changes in linker script.
Changes required because of the above.
Do not patch hardcoded_* variables but assign to them instead.

Cosmetic changes here and there.
 
97 6940 d 17 h jermar /SPARTAN/trunk/ Add context_set() macro to support extended behaviour for architectures with more than one stack (e.g. IA-64).
Now there is one generic context_set() defined in include/context.h and one IA-64 specific defined in arch/ia64/include/context.h.
 
81 6948 d 9 h jermar /SPARTAN/trunk/ Add SP_DELTA macro for each architecture.
On IA-32, this macro represents two doublewords that must be on the stack when switching to a new stack.
On MIPS, there is no need to fix sp when switching to a new stack.
On IA-64, this macro is used to allocate the 16-byte scratch area.

IA-64 work.
Changes in start.S. More changes to come.
Define memcopy().

Janitorial fixes.
Add missing #include <panic.h> to rwlock4/test.c.
Remove wrong use of inline keyword from both declaration and definition of l_apic_id().
