1940 6457 d 8 h decky /trunk/kernel/arch/amd64/ amd64: fix compilation, keyboard not checked yet  
1939 6457 d 8 h decky /trunk/ ia32: fix compilation, keyboard not checked yet  
1937 6457 d 15 h decky /trunk/kernel/arch/ remove orphaned functions  
1936 6457 d 15 h decky /trunk/kernel/arch/mips32/ mips32: update for new IRQ subsystem  
1934 6457 d 17 h decky /trunk/kernel/arch/ppc32/src/drivers/ remove grab (not needed)  
1932 6458 d 5 h jermar /trunk/kernel/ Do not copy notification config out of the IRQ structure.
Add the notify member, that toggles notifications on and off instead.
This is good for preventing other tasks from registering the notification
while the notification config is stored outside the IRQ structure.
It should also help to implement the cleanup code.
 
1931 6458 d 6 h jermar /trunk/ Add support for IPC notifications even for polled ns16550 based keyboard.  
1930 6458 d 10 h decky /trunk/kernel/arch/ppc64/ ppc64: make it compile again  
1928 6458 d 10 h decky /trunk/ ppc32: update for new IRQ subsystem (there is still a bug left)  
1926 6458 d 15 h decky /trunk/kernel/ cleanup for new IRQ subsystem  
1923 6459 d 5 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 6460 d 13 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 6461 d 6 h jermar /trunk/kernel/ Changes in ns16550 and z8530 drivers.
Add some stuff for IRQ notifications to irq_t.
 
1920 6461 d 14 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 6462 d 5 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 6466 d 5 h jermar /trunk/kernel/arch/sparc64/src/mm/ Omitted comma.  
1917 6466 d 6 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.
 
1916 6467 d 4 h jermar /trunk/kernel/arch/sparc64/src/trap/ Small change of code organization.
No functional difference.
 
1915 6467 d 5 h jermar /trunk/kernel/ A quote from from SPARC V9 specification:

The Y register is deprecated; it is provided only for compatibility with previous versions
of the architecture. It should not be used in new SPARC-V9 software. It is
recommended that all instructions that reference the Y register (i.e., SMUL,
SMULcc, UMUL, UMULcc, MULScc, SDIV, SDIVcc, UDIV, UDIVcc, RDY, and
WRY) be avoided. See the appropriate pages in Appendix A, “Instruction Definitions,”
for suitable substitute instructions.

Still gcc is generating code which uses Y and some of the instructions above.
This change modifies the preemptible_handler() to preserve the Y register
across preemption.
 
1912 6468 d 14 h jermar /trunk/kernel/ Separate mapping of EBUS interrupts into two parts: EBUS and PCI.
