/trunk/
Convert sparc64 framebuffer code to configure from the OpenFirmware device tree memory representation.
1896
6578 d 8 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.

sparc64 work:
- find a CPU node and read its clock_frequency attribute
- implement asm_delay_loop()
- set TICK_COMPARE register according to processor frequency
- small improvements at random places
OpenFirmware work:
- two new functions for walking the device tree
Generic boot loader work:
- added basic string functions
Usual pile of indentation and formatting fixes.

- Changes to enable userspace keyboard drivers.
- Fix z8530 initialization (i.e. clear any pending Tx interrupts).
- Experimental support for framebuffers with inverted colors.
1860
6600 d 11 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.

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.
1848
6620 d 20 h
jermar
/trunk/kernel/
Rework the z8530 driver so that it is based on z8530 specification rather
than on accidental and limited "compatibility" with i8042.
1844
6622 d 11 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
6622 d 16 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
6622 d 17 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.

/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
6651 d 11 h
decky
/
move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot
1784
6652 d 9 h
jermar
/kernel/trunk/
Sync OpenFirmware functionality with boot.
Random cleanup.
1780
6658 d 13 h
jermar
/kernel/trunk/
Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).

Kernel doxygen comments updated.

6699 d 16 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.
1377
6704 d 16 h
jermar
/kernel/trunk/arch/sparc64/include/drivers/
Remove unneeded macro.

6771 d 10 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.
897

jermar
/kernel/trunk/
sparc64 work.
Fix KBD_VIRT_ADDRESS.
Call before_thread_runs() prior to the switch to the thread's stack. Add comment why this is crucial.
Add after_thread_ran() to the scheduler.
Add before_thread_runs_arch() and after_thread_ran_arch() for sparc64, mapping/demapping thread's kernel stack.
Add dummy after_thread_ran_arch() to all other architectures.
Add dtlb_insert_mapping() to promote code reuse.

sparc64 work.
Very raw and fragile preliminary standalone keyboard support - polling mode only.
Because of a workaround in Simics, the scan codes are the same as on ia32.
894
6785 d 13 h
jermar
/kernel/trunk/
Move i8042 driver to genarch as it might be used by more architectures.
889
6786 d 17 h
jermar
/kernel/trunk/arch/sparc64/include/drivers/
Forgotten fb.h for sparc64.

Tick interrupt support.

Interrupt Levels 1 - 15 serviced.
Minor changes in the exc_* functions.
