4605 5612 d 11 h decky /branches/snapshot/ add task snapshoting branch  
4556 5626 d 16 h decky /trunk/ define endianess externally to be able to exactly specify whether we are using UTF-32LE or UTF-32BE
quit messing with BOM in UTF-32
 
4119 5723 d 15 h decky /trunk/ get back support for framebuffer and keyboard for sparc64 (generic)  
4047 5729 d 4 h jermar /trunk/ Improve the configuration file.

- Support for easy configuration with sane defaults.

- Fix the ambiguous MACHINE variable by introducing the PROCESSOR variable.

- Eliminate some unnecessarily detailed questions by providing defaults for the
Serengeti machine.

- Introduce CONFIG_HID_IN and CONFIG_HID_OUT variables. They help to limit the
number of offered HID devices. In the future, they can be also used to
configure the way how the serial controller devices are connected to the
keyboard / serial line modules on some platforms where we can't autodetect.
 
3879 5752 d 4 h decky /trunk/kernel/arch/ simplify configuration in Makefiles  
3865 5756 d 2 h rimsky /trunk/ Allow to suppress compilation of FB code on Sparc machines that do not have FB.  
3672 5821 d 4 h jermar /trunk/ Merge sparc branch to trunk.  
3654 5827 d 6 h jermar /trunk/kernel/arch/sparc64/ After my effort yesterday, there are two rival psycho drivers.
Merge the two and remove the newer one.
 
3647 5828 d 3 h jermar /trunk/kernel/arch/sparc64/ Improvized Psycho driver.  
3368 5921 d 8 h decky /trunk/ configurable cross-compiler prefix (using CROSS_PREFIX)  
2725 6124 d 10 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 6206 d 8 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 6369 d 4 h jermar /trunk/kernel/ Replace gcc-specific __FUNCTION__ with C99 __func__.
suncc's xregs=no%float can be used only on sparc64.
 
2460 6369 d 4 h jermar /trunk/kernel/ Better infrastructure for building with different compilers.
Separate ICC_CFLAGS added, SUNCC_CFLAGS extended.
 
2454 6370 d 3 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 6440 d 1 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 6484 d 4 h decky /trunk/ experimental support for Objective C
(disabled by default)
 
2071 6509 d 4 h jermar /trunk/ (c) versus (C)  
2009 6553 d 3 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2008 6555 d 4 h jermar /trunk/kernel/arch/sparc64/ Add dcache_flush() function that flushes D-Cache on sparc64.  
1911 6612 d 2 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 6621 d 4 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 6625 d 11 h jermar /trunk/ Convert sparc64 framebuffer code to configure from the OpenFirmware device tree memory representation.  
1896 6626 d 3 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 6628 d 4 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 6630 d 2 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).
 
1889 6631 d 4 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 6634 d 7 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1882 6635 d 11 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1875 6641 d 4 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 6644 d 5 h jermar /trunk/kernel/ sparc64 kernel fixes  
1862 6647 d 7 h jermar /trunk/kernel/ sparc64 work.
Kernel syscall support.
Modify the preemptive_handler for the use by syscalls.
 
1854 6650 d 13 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 6662 d 13 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 6670 d 6 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 6670 d 11 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 6670 d 12 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 6675 d 9 h jermar /trunk/kernel/ Add scan code map for Sun keyboard.  
1802 6694 d 0 h decky /trunk/ cleanup and unify the build system  
1790 6697 d 7 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.
