4692 5383 d 6 h svoboda /branches/tracing/ Merge trunk changes up to r4686.  
4377 5483 d 6 h svoboda /branches/tracing/ Merge latest trunk changes to tracing. (i.e. revs 3684:4374, huge). This time hopefully the real thing.  
3675 5640 d 4 h svoboda /branches/tracing/ Merge latest trunk changes to tracing.  
3425 5720 d 16 h svoboda /branches/tracing/ Merge latest trunk changes into tracing (broken)  
2787 5893 d 9 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2725 5943 d 11 h decky /trunk/kernel/ remove config.memory_size, get_memory_size() and memory_init.{c|d}
the amount of available memory can be calculated from the sizes of the zones
add FRAMES2SIZE, SIZE2KB and SIZE2MB functions/macros (code readability)
 
2610 6025 d 9 h jermar /trunk/ Support for six syscall arguments for sparc64.
There is a minor stability issue which needs to be fixed (kernel panics upon entering kconsole from the
console task).
 
2462 6188 d 5 h jermar /trunk/kernel/ Replace gcc-specific __FUNCTION__ with C99 __func__.
suncc's xregs=no%float can be used only on sparc64.
 
2460 6188 d 6 h jermar /trunk/kernel/ Better infrastructure for building with different compilers.
Separate ICC_CFLAGS added, SUNCC_CFLAGS extended.
 
2454 6189 d 4 h jermar /trunk/kernel/ A bit of infrastructure for building with different compilers.
CFLAGS split into GCC_CFLAGS and SUNCC_CFLAGS.
As of now, there are no separate ICC_CFLAGS, but can be easily added.
 
2141 6259 d 2 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.
 
2125 6303 d 6 h decky /trunk/ experimental support for Objective C
(disabled by default)
 
2071 6328 d 5 h jermar /trunk/ (c) versus (C)  
2009 6372 d 4 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2008 6374 d 5 h jermar /trunk/kernel/arch/sparc64/ Add dcache_flush() function that flushes D-Cache on sparc64.  
1911 6431 d 3 h jermar /trunk/kernel/ Add support for interrupt mapping in the Sabre PCI controller.
Add support for PCI and EBUS interrupt mapping via the OpenFirmware device tree.
Unfortunatelly, the code is not capable enough to earn single ns16550 interrupt.
I suspect something needs to be enabled in the EBUS registers.
 
1903 6440 d 6 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.
 
1897 6444 d 13 h jermar /trunk/ Convert sparc64 framebuffer code to configure from the OpenFirmware device tree memory representation.  
1896 6445 d 4 h jermar /trunk/ Convert sparc64 to detect keyboard and determine
its physical address by walking the memory representation
of the OpenFirmware device tree.

Add bus-specific functions that know how to apply the
"ranges" property to one component of the "reg" property.
Buses supported so far include FHC, EBUS and PCI.
 
1895 6447 d 5 h jermar /trunk/ More ofw_tree work and fixes.
Add ofw_tree_lookup().
Every ofw_tree_node now also contains a disambigued name which is essential for tree lookups.
 
1891 6449 d 4 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).
 
1889 6450 d 6 h jermar /trunk/kernel/ Fix bug in mm/as.c:
- as_area_destroy() should not work with AS but as

sparc64 work:
- start implementing TSB support
 
1888 6453 d 9 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1882 6454 d 12 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1875 6460 d 6 h jermar /trunk/ sparc64 work.
- Changes to enable userspace keyboard drivers.
- Fix z8530 initialization (i.e. clear any pending Tx interrupts).
- Experimental support for framebuffers with inverted colors.
 
1865 6463 d 7 h jermar /trunk/kernel/ sparc64 kernel fixes  
1862 6466 d 9 h jermar /trunk/kernel/ sparc64 work.
Kernel syscall support.
Modify the preemptive_handler for the use by syscalls.
 
1854 6469 d 15 h jermar /trunk/kernel/ Define architecture-specific thread sub-constructors and sub-destructors on all architectures.
Define the THREAD_FLAG_USPACE which means that the thread runs in user space.
The forementioned changes allow for allocating of user window buffer on sparc64
threads that execute in userspace.

A lot of formatting and indentation fixes.
 
1849 6481 d 14 h jermar /trunk/kernel/ sparc64 work.
interrupt_vector trap experimental handling.
Minimal reverse-engineered FireHose Controller driver (documentation needed!).
Keyboard on Sun Enterprise is now interrupt driven. Keyboard on Sun Ultra
is still polled.
 
1844 6489 d 7 h jermar /trunk/kernel/ Add an option to compile the sparc64 kernel for Ultra 5 or Enterprise E6500.
Basic keyboard support (polling) based on ns16550 serial port (deployed on Ultra).
 
1842 6489 d 12 h jermar /trunk/kernel/ i8042 and z8530 separated, the tree compiles again.
Now there is some duplicated code in i8042.c and z8530.c,
but that can be eliminated in slower pace.
 
1841 6489 d 13 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.
 
1838 6494 d 10 h jermar /trunk/kernel/ Add scan code map for Sun keyboard.  
1802 6513 d 1 h decky /trunk/ cleanup and unify the build system  
1790 6516 d 8 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.
 
1787 6518 d 7 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1777 6525 d 11 h jermar /kernel/trunk/ Make sparc64 kernel assume it is loaded by our loader.  
1410 6566 d 12 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 6570 d 5 h decky /kernel/trunk/ make hardware memory mapping more generic  
1376 6571 d 12 h jermar /kernel/trunk/ Change the way the framebuffer is mapped so that sparc64 is usable again.
