2439 6226 d 12 h decky /trunk/kernel/arch/ia32/src/ fix ICC compilation  
2218 6280 d 10 h decky /trunk/kernel/ support the possibility to send EOI or Interrupt Acknowledgement
prior to processing the interrupt
(this is essential on some architectures to prevent preemption deadlock)
 
2107 6343 d 12 h jermar /trunk/ When clock() is called by an external interrupt dispatched by the IRQ dispatcher,
no spinlock can be held or the kernel will not be preemptive. This fixes Ticket #24.

Formating and indentation fixes.
 
2089 6349 d 20 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6360 d 13 h jermar /trunk/ (c) versus (C)  
2065 6374 d 12 h jermar /trunk/kernel/ Coding style fixes and formatting improvements.  
2018 6397 d 16 h decky /trunk/kernel/ rename rdtsc() to get_cycle()  
2015 6399 d 13 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.
 
1993 6416 d 21 h decky /trunk/ make framebuffer code more generic  
1956 6442 d 22 h decky /trunk/kernel/ ia32: adopt new IRQ interface, mouse not tested yet  
1837 6527 d 1 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.
 
1787 6550 d 15 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6557 d 16 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1754 6571 d 22 h jermar /kernel/trunk/ Indentation and some improved comments.
Remove forgotten comment from gxemul.sh.
 
1702 6578 d 19 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1667 6583 d 17 h jermar /kernel/trunk/ Print spurious interrupt messages only when compiled with CONFIG_DEBUG.
Print warning about looping spinlock only after 100000000 unsuccessfull attempts to gain the spinlock.
 
1477 6591 d 4 h decky /kernel/trunk/arch/ cleanup  
1473 6591 d 14 h decky /kernel/trunk/ kernel support for text-only framebuffer  
1371 6604 d 12 h decky /kernel/trunk/ unify the framebuffer API
use physical address as the base address for the framebuffer
 
1327 6608 d 19 h decky /kernel/trunk/ split framebuffer initialization and sysinfo registration  
1318 6609 d 14 h vana /kernel/trunk/ Sysinfo userspace interface  
1313 6609 d 21 h jermar /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().
 
1311 6610 d 19 h jermar /kernel/trunk/arch/ia32/src/drivers/ Fix number of frames allocated for VESA frame buffer in the singular
case when the frame buffer size is below FRAME_SIZE.
 
1310 6610 d 21 h jermar /kernel/trunk/ Change coding style in vesa.c and do some minor changes.  
1296 6615 d 20 h vana /kernel/trunk/arch/ia32/src/drivers/ new line only if no clrscr  
1292 6617 d 19 h vana /kernel/trunk/arch/ VESA FB cut unwanted  
1289 6617 d 20 h vana /kernel/trunk/arch/ Amd64 framebuffer  
1287 6617 d 23 h vana /kernel/trunk/ ia32 VESA FB support  
958 6670 d 14 h jermar /kernel/trunk/ Nicer ia32 interrupt handlers and structures holding interrupted context data.
Unify the name holding interrupted context data on all architectures to be istate.
 
894 6684 d 17 h jermar /kernel/trunk/ Move i8042 driver to genarch as it might be used by more architectures.  
893 6684 d 21 h jermar /kernel/trunk/arch/ sparc64 work.
Revive OFW console code and use it before the kernel switches to standalone console.

ia32 + ia64 cosmetic changes.
 
878 6686 d 20 h vana /kernel/trunk/ Active keyboard read for ia32  
756 6711 d 10 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 6712 d 9 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.
 
687 6734 d 17 h jermar /kernel/trunk/ Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.
 
671 6740 d 13 h vana /kernel/trunk/ i8042 bug fix...  
670 6740 d 16 h vana /kernel/trunk/arch/ia32/src/drivers/ i8042 command word init... It should work on ia32 but I have done it for Indy and I'm not sure it will work because on Silicon should not be the same software in universal microprocesor i8042. So if It will not work I'll remove it and will write i8042 AT function emulation.  
623 6758 d 23 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.
 
606 6761 d 18 h palkovsky /kernel/trunk/ Small kconsole readline changes.
Some mips tweaks to allow for real keyboard support in indy.
 
601 6762 d 14 h palkovsky /kernel/trunk/ Added some readline functionality to kconsole.
Arrows editing, history, tab completion.
