1987 6410 d 13 h jermar /trunk/kernel/arch/sparc64/src/ Take the possible difference between kernel and physical address into account in TSB and userspace window buffer
allocation and deallocation code.		  
1986 6410 d 16 h decky /trunk/kernel/arch/sparc64/src/drivers/ The FFB framebuffer looks more like 32b  
1984 6411 d 12 h jermar /trunk/kernel/arch/sparc64/ sparc64 work:
- untested support for Psycho PCI controller		  
1983 6412 d 16 h jermar /trunk/kernel/arch/sparc64/src/mm/ sparc64 work:
- fix computation of the frame allocator configuration frame
- mark the first physical frame unavailable, no matter what is its address

Because of that, we can now boot past the frame_arch_init() on the Ultra 60 now.		  
1982 6412 d 19 h jermar /trunk/ Modify the sparc64 startup code to not cause MMU traps before it takes over the TLB and
the trap table. Fix several PA2KA and KA2PA omittions or errors. Fix configuration to pass
the DEFS variable along.		  
1978 6413 d 12 h jermar /trunk/ sparc64 code to support physical memory that starts on non-zero addresses.
Still needs to be tested on systems with such setup.		  
1977 6414 d 8 h jermar /trunk/ Fix bad indentation in ofw.c

sparc64 work:
o Fix copyright in main.c
o Move code from unused parts of the trap table.		  
1976 6419 d 17 h jermar /trunk/kernel/arch/sparc64/ sparc64 context does not have to include the CLEANWIN register.  
1975 6423 d 10 h jermar /trunk/kernel/arch/sparc64/src/ Typo.  
1960 6434 d 11 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix the following bug:

Ticket #3 data_access_exception after killing task on sparc64		  
1954 6435 d 10 h jermar /trunk/ Minor changes. Some coding style fixes and also a type (tee vs. tree).
One AS -> as change.		  
1946 6442 d 9 h jermar /trunk/kernel/arch/sparc64/ sparc64 work.
- Improve panic screen on data_access_exception
by dumping contents of DSFSR and DSFAR.
- Change the FHC enable interrupt code to only
set the IMAP_V bit.		  
1931 6444 d 13 h jermar /trunk/ Add support for IPC notifications even for polled ns16550 based keyboard.  
1923 6445 d 11 h jermar /trunk/ Replace the old IRQ dispatcher and IPC notifier with new implementation.
Note that all architectures except for sparc64 are now broken
and don't even compile.		  
1922 6446 d 19 h jermar /trunk/kernel/ More IRQ stuff.
Modify the IRQ hash table functions to support lookup based on inr and devno.
Add method member to irq_t.		  
1921 6447 d 12 h jermar /trunk/kernel/ Changes in ns16550 and z8530 drivers.
Add some stuff for IRQ notifications to irq_t.		  
1920 6447 d 20 h jermar /trunk/kernel/ Move the new IRQ redirector to ddi/.
Add function for assigning unique device numbers.
Change sparc64/drivers/kbd.c to assign devno to keyboard.		  
1919 6448 d 11 h jermar /trunk/kernel/ Prototypical implementation of new IRQ redirector in sparc64.
The new code can support shared IRQs in kernel (and multiple IRQs per device).
Userspace support is yet to be written.
The only architecture that uses this code is actually sparc64 only.		  
1918 6452 d 11 h jermar /trunk/kernel/arch/sparc64/src/mm/ Omitted comma.  
1917 6452 d 12 h jermar /trunk/ sparc64 work:
- hw_map() can now support up to 8M requests
- CPU stacks are now locked in DTLB of the respective processor
- kernel in the boot phase no longer relies on the stack provided by OpenFirmware
- instead of of doing FLUSHW during kernel startup, simply set the
window state registers to the wanted state
- NWINDOW -> NWINDOWS
- Add/fix some comments and copyrights.
