2019 6445 d 2 h decky /trunk/kernel/ prepare for new test infrastructure  
2015 6447 d 0 h jermar /trunk/ Rework support for virtually indexed cache.
Instead of repeatedly flushing the data cache, which was a huge overkill, refuse to create an illegal address alias
in the kernel (again) and allocate appropriate page color in userspace instead. Extend the detection also to
SYS_PHYSMEM_MAP syscall.

Add support for tracking physical memory areas mappable by SYS_PHYSMEM_MAP.

Lots of coding style changes.		  
2012 6449 d 22 h jermar /trunk/ Eliminate confusion between SYS_MAP_PHYSMEM and sys_physmem_map.
The syscall is to be called SYS_PHYSMEM_MAP from now on and the functions that participate in its implementation are
called *physmem_map().		  
2009 6451 d 23 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2007 6454 d 22 h jermar /trunk/kernel/ Introduce page colors. So far, only sparc64 uses correct page color bits. Other architectures have a dummy define
specifying zero bits for a page color.

There is a new check of page color in as_area_share(). Because of lack of support for this in the userspace, the
check has been #ifef'ed out.

1950 6495 d 3 h jermar /trunk/kernel/ Indentation changes and coding style fixes in slab.c and slab.h.  
1941 6499 d 3 h decky /trunk/kernel/generic/include/ cleanup  
1935 6499 d 11 h decky /trunk/kernel/generic/include/ add function type  
1933 6499 d 23 h jermar /trunk/kernel/generic/ Implement efficient IPC notification cleanup.  
1932 6500 d 0 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.		  
1927 6500 d 6 h decky /trunk/kernel/generic/include/ remove dummy definitions (which tent to lead to mysterious bugs)  
1924 6500 d 23 h jermar /trunk/kernel/generic/ For the sake of clarity, get rid of negative INR for virtual interrupts.
This way, the code can hurt performance on systems where the non-negative klog INR overlaps
with a frequently used INR such as system clock on amd64 and ia32.		  
1923 6501 d 0 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 6502 d 8 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 6503 d 1 h jermar /trunk/kernel/ Changes in ns16550 and z8530 drivers.
Add some stuff for IRQ notifications to irq_t.		  
1920 6503 d 9 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 6504 d 0 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.		  
1914 6509 d 6 h jermar /trunk/kernel/generic/ Add function for printing out info about address space.  
1901 6521 d 5 h jermar /trunk/kernel/ Make SMP related parts of main.c more generic.
Move initialization of local APIC to architecture specific code.
Add arch_post_cpu_init() to support the above.		  
1896 6524 d 23 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.		  
1894 6527 d 22 h jermar /trunk/ Add balloc() (a.k.a boot allocator):
- balloc() only needs to know how to allocate memory.
- Memory allocated via balloc() is supposed to be passed to kernel and never freed by boot itself.
- make kernel aware of boot allocations

More work on OFW device tree:
- use balloc() to efficiently and safely allocate memory for the canonical copy of the device tree

sparc64 boot:
- pass OFW device tree root node pointer to kernel		  
1891 6528 d 22 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).
