2020 6426 d 3 h decky /trunk/kernel/ integrate more tests  
2019 6426 d 4 h decky /trunk/kernel/ prepare for new test infrastructure  
2015 6428 d 2 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 6431 d 0 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 6433 d 1 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2007 6436 d 0 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.

1999 6439 d 11 h decky /trunk/ start RAM disk support  
1981 6449 d 10 h jermar /trunk/kernel/ Indentation, formatting and minor changes.  
1972 6462 d 8 h jermar /trunk/ Modify selected function to consume less stack space.

Avoid flushw instruction in the sparc64 loader.
 
1954 6472 d 1 h jermar /trunk/ Minor changes. Some coding style fixes and also a type (tee vs. tree).
One AS -> as change.
 
1951 6476 d 4 h jermar /trunk/kernel/generic/include/mm/ Fix comma mistakenly removed in last commit.  
1950 6476 d 5 h jermar /trunk/kernel/ Indentation changes and coding style fixes in slab.c and slab.h.  
1941 6480 d 5 h decky /trunk/kernel/generic/include/ cleanup  
1935 6480 d 12 h decky /trunk/kernel/generic/include/ add function type  
1933 6481 d 1 h jermar /trunk/kernel/generic/ Implement efficient IPC notification cleanup.  
1932 6481 d 2 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.
 
1929 6481 d 7 h decky /trunk/kernel/generic/src/console/ ipc_irq_send_msg(NULL, 0, 0, 0) is definitively a bug  
1927 6481 d 7 h decky /trunk/kernel/generic/include/ remove dummy definitions (which tent to lead to mysterious bugs)  
1926 6481 d 12 h decky /trunk/kernel/ cleanup for new IRQ subsystem  
1924 6482 d 1 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 6482 d 1 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 6483 d 10 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 6484 d 3 h jermar /trunk/kernel/ Changes in ns16550 and z8530 drivers.
Add some stuff for IRQ notifications to irq_t.
 
1920 6484 d 11 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 6485 d 2 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.
 
1915 6490 d 2 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.
 
1914 6490 d 8 h jermar /trunk/kernel/generic/ Add function for printing out info about address space.  
1904 6500 d 7 h jermar /trunk/kernel/ IPI/cross-call support for sparc64.
SMP on sparc64 is now fully supported.
