4718 5567 d 4 h mejdrech /branches/network/ Net: merge with trunk head (0.4.1)  
4327 5723 d 9 h mejdrech /branches/network/ Net: *merged with trunk 4326, +ne2k irq debug  
4263 5738 d 22 h mejdrech /branches/network/ Net: merged with trunk:4261  
3386 5957 d 1 h decky /branches/network/ add new network branch (copy of current trunk)  
3274 5981 d 2 h jermar /trunk/ memcpy(), memmove() and similar functions return dst instead of src.
Fix all implementations, including those in assembly. ppc32 assembly
version didn't seem to be affected by this.
 
3222 6014 d 1 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
2228 6470 d 3 h jermar /trunk/kernel/arch/sparc64/src/ Fix ticket #28.
In switch_to_userspace(), the uarg argument is in %i2, not in %i3.
 
2071 6551 d 21 h jermar /trunk/ (c) versus (C)  
1882 6678 d 4 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1880 6680 d 20 h jermar /trunk/ Small improvements here and there.  
1865 6686 d 22 h jermar /trunk/kernel/ sparc64 kernel fixes  
1864 6687 d 18 h jermar /trunk/ sparc64 update.
- Prototype userspace layer implementation that
at least relates to sparc64 and compiles cleanly.
- Fixes for kernel's preemptible_handler and code
related to running userspace.
- Enable userspace. Several dozen instructions
are now run in userspace! We are pretty near
the userspace milestone for sparc64.
 
1860 6690 d 22 h jermar /trunk/kernel/ A lot of untested sparc64 stuff:
- Write ASID to hardware when a thread is about to run in userspace.
- Add userspace() and switch_to_userspace() functions.
- Handle special cases when the userspace spill/fill handler causes MMU trap.
- Resolve some TODOs in the existing sparc64 code.
- sparc64 has now C99 compliant header guards.
- Formatting and indentation fixes.
 
1856 6692 d 6 h jermar /trunk/kernel/ sparc64 work.
- Modify before_thread_runs_arch() to store addresses of the kernel stack and
userspace window buffer, resp., to registers %g6 and %g7, resp, in the
alternate and interrupt global sets.
- Modify after_thread_ran_arch() to sample %g7 from the alternate globals.
- Implement trap handler for spilling register windows into userspace window buffer.
- Implement assembly language functions to access %g6 and %g7 registers in the alternate sets.
- Initialize the trap table so that there are now also spill_1_normal, spill_2_normal,
spill_0_other and fill_1_normal handlers. These handlers are used in different situations
and for different purposes.
 
1790 6740 d 0 h jermar /trunk/ 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.
 
1789 6740 d 2 h jermar /trunk/ Fix ofw_memmap() in boot infrastructure.
The cell size is 32-bit and not equal sizeof(ofw_arg_t).
Define architecture dependant #address-cells and #size-cells for cases
the respective properties are missing in the OpenFirmware device tree.
The algorithm now works both for ppc32 and sparc64.

Add memmap_t, screen_t and keyboard_t to sparc64 bootinfo structure.
Be more verbose during sparc64 boot.

Move ALIGN_UP to generic part of boot/.

Change header guards in several places so that they don't contain double underscore.
 
1787 6741 d 23 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1784 6742 d 20 h jermar /kernel/trunk/ Sync OpenFirmware functionality with boot.
Random cleanup.
 
1288 6809 d 5 h jermar /kernel/trunk/ Complete implementation of copy_from_uspace() and copy_to_uspace()
for amd64 and ia32. Other architectures still compile and run,
but need to implement their own assembly-only memcpy(), memcpy_from_uspace(),
memcpy_to_uspace() and their failover parts. For these architectures
only dummy implementations are provided.
 
534 6960 d 21 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.
