762 6673 d 6 h palkovsky /kernel/trunk/ Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference		  
689 6698 d 3 h bondari /kernel/trunk/ Frame alloc test #1  
673 6702 d 22 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.		  
646 6718 d 21 h jermar /kernel/trunk/ Fix cpu_init(): frame_alloc() can return 0 as the valid address of block of frames. Do not signal error.

sparc64 work.
Reorganize kernel vs. userspace memory layout.
Add panic_printf().
Turn dummy() into nop rather than into infinite loop.		  
623 6722 d 9 h jermar /kernel/trunk/ Add SPINLOCK_DECLARE and SPINLOCK_INITIALIZE macros.
SPINLOCK_DECLARE is to be used instead of direct spinlock_t declarations
in dynamically allocated structures on which spinlock_initialize() is called after
their creation.
SPINLOCK_INITIALIZE is to be used instead of direct spinlock_t declarations
of global spinlocks. It declares and initializes the spinlock.
Moreover, both macros are empty on UP so that -Wall warnings about unused structures
get supressed.		  
548 6731 d 0 h jermar /kernel/trunk/ Cleanup and fixes.  
534 6733 d 0 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6733 d 0 h bondari /SPARTAN/trunk/ Buddy allocator for physical memory complete implementation.
Tested on IA32, AMD64, MIPS32. RWLock Test #5 is not passed.
NOTE: Other architectures could be broken (but should not be)		  
532 6733 d 0 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6745 d 5 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
458 6759 d 7 h decky /SPARTAN/trunk/ make configuration variables usage consistent  
430 6765 d 21 h jermar /SPARTAN/trunk/ Move src/ and include/ to generic.  
192 6829 d 2 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.		  
125 6874 d 22 h jermar /SPARTAN/trunk/ Huge indentation fix.  
108 6917 d 5 h decky /SPARTAN/trunk/ doxygen-style comments
NDEBUG in Makefile.config		  
31 6955 d 3 h jermar /SPARTAN/trunk/ Replace the deadlock-prone TLB shootdown algorithm with a deadlock-free implementation.
The implementation is a variant of the CMU TLB consistency algorithm.
Very inefficient implementation of a very inefficient (but correct) algorithm.		  
28 6956 d 7 h jermar /SPARTAN/trunk/ Small improvements.  
24 6962 d 0 h jermar /SPARTAN/trunk/ Small fixes.  
20 6968 d 6 h jermar /SPARTAN/trunk/ Smarter definition of CPU macro.  
16 6971 d 3 h jermar /SPARTAN/trunk/ Switch from mm-based 'the' mechanism to macro-based 'cpu_private_data[CPU_ID_ARCH]' mechanism.
Added l_apic_id() and some other minor APIC changes.
Move gdtr to K_DATA_START section.
Move K_DATA_START section immediately behind K_TEXT_START section so that real-mode addresses work even with growing size of kernel code.
