4327 5677 d 0 h mejdrech /branches/network/ Net: *merged with trunk 4326, +ne2k irq debug  
4153 5714 d 13 h mejdrech /branches/network/ Networking: merged with trunk changes  
4148 5714 d 22 h decky /trunk/ as kernel little brother drivers are not needed anymore, the device numbers do not have to be correlated between kernel and uspace in any way
introduce new syscall sys_device_assign_devno() for generating system-wide unique device numbers for uspace
 
4119 5720 d 0 h decky /trunk/ get back support for framebuffer and keyboard for sparc64 (generic)  
4094 5720 d 15 h decky /trunk/kernel/genarch/ update for the new scheme of wiring device drivers to keyboard/serial modules  
4042 5725 d 16 h jermar /trunk/ Complete emancipation of kernel serial controller drivers (i8042, ns16550 and
z8530). Provide a common keyboard module for PC and Sun keyboards. The serial
line module is still to follow.
 
3961 5738 d 17 h jermar /trunk/ Unbreak sparc64.
Due to the lack of userspace bus drivers for the z8530 and ns16550,
we are currently handling exactly one interrupt from these devices
in userspace.
 
3941 5740 d 12 h jermar /trunk/kernel/ Let IRQ claim methods take irq_t * instead of the instance argument.  
3906 5745 d 9 h jermar /trunk/kernel/ IRQ handlers are using one superfluous argument and an unused elipsis.
On the other hand, IRQ claim functions would need to be passed the instance
argument.
 
3655 5823 d 12 h jermar /trunk/kernel/ Add additional members to the irq_t structure so that an interrupt-driven driver
does not need to know how to clear the level interrupt. The z8530 was modified
in this way and is much more generic. The ns16550 driver has also been modified,
but awaits testing. The sparc64 interrupt mapping and dispatch code is now using
the new info and calls the clear-interrupt-routine itself.
 
2089 6494 d 19 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6505 d 12 h jermar /trunk/ (c) versus (C)  
1921 6600 d 13 h jermar /trunk/kernel/ Changes in ns16550 and z8530 drivers.
Add some stuff for IRQ notifications to irq_t.
 
1920 6600 d 21 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 6601 d 12 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.
 
1896 6622 d 11 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.
 
1875 6637 d 13 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.
 
1849 6658 d 21 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.
 
1842 6666 d 19 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 6666 d 20 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.
