3865 5655 d 5 h rimsky /trunk/ Allow to suppress compilation of FB code on Sparc machines that do not have FB.  
3852 5662 d 9 h jermar /trunk/kernel/arch/sparc64/src/drivers/ Fix sparc64 build.  
3844 5663 d 6 h decky /trunk/ silent kernel console output when user space console is active  
3790 5686 d 15 h svoboda /trunk/kernel/ Make newlines in panic messages consistent. Add periods at end of messages so that it is obvious whether they are printed entirely.  
3788 5687 d 4 h svoboda /trunk/kernel/ Unify newlines in fault_if_from_uspace() format strings. (Remove them and print newline automatically). Also start messages with caps.  
3749 5699 d 3 h jermar /trunk/kernel/arch/sparc64/src/trap/ Support for preemptible syscalls on sparc64.  
3740 5700 d 11 h jermar /trunk/kernel/arch/sparc64/ Fix typo.  
3736 5701 d 13 h decky /trunk/kernel/arch/sparc64/ refresh kernel console during grab on sparc64  
3714 5708 d 11 h decky /trunk/kernel/ do not waist resources if no keyboard driver is used  
3679 5719 d 2 h rimsky /trunk/ Added forgotten stuff related to framebuffers with offsets. Got rid of VISUAL_SB1500_PALETTE.  
3672 5720 d 7 h jermar /trunk/ Merge sparc branch to trunk.  
3655 5726 d 7 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.
 
3654 5726 d 9 h jermar /trunk/kernel/arch/sparc64/ After my effort yesterday, there are two rival psycho drivers.
Merge the two and remove the newer one.
 
3649 5727 d 4 h jermar /trunk/kernel/arch/sparc64/src/drivers/ More work on the psycho driver.  
3647 5727 d 6 h jermar /trunk/kernel/arch/sparc64/ Improvized Psycho driver.  
3646 5727 d 8 h jermar /trunk/kernel/ Initial support for interrupt driven driver for ns16550.  
3577 5744 d 19 h vana /trunk/kernel/ Support for serial port console on IA64 as a compensation for keyboard - based on SPARC ns16550 driver  
3482 5784 d 7 h jermar /trunk/kernel/arch/sparc64/ Do not allocate full page for the uspace window buffer.
Instead, allocate only the bare minimum to fit NWINDOWS - 1
uspace windows and to satisfy alignment requirements.
 
3463 5796 d 12 h jermar /trunk/kernel/arch/sparc64/ Populate all sparc64 trap table slots belonging to trap_instruction_n.  
3458 5797 d 6 h jermar /trunk/kernel/arch/sparc64/src/trap/ Add sparc64 trap table entries so that the maximum syscall number is 0x40.  
3274 5837 d 12 h jermar /trunk/ memcpy(), memmove() and similar functions return dst instead of src.
Fix all implementations, including those in assembly. ppc32 assembly
version didn't seem to be affected by this.
 
3222 5870 d 11 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3133 5895 d 6 h jermar /trunk/kernel/arch/ Add smc_coherence() macro to all architectures.
So far, only amd64, ia32, ia64 and sparc64 are implemented.
 
3104 5902 d 19 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3071 5905 d 12 h decky /trunk/kernel/ reflect changes in generic code
proper formatting directives
coding style
 
2860 5954 d 7 h cejka /trunk/ Context handling unified for sparc64.  
2745 6002 d 15 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2725 6023 d 13 h decky /trunk/kernel/ remove config.memory_size, get_memory_size() and memory_init.{c|d}
the amount of available memory can be calculated from the sizes of the zones
add FRAMES2SIZE, SIZE2KB and SIZE2MB functions/macros (code readability)
 
2610 6105 d 11 h jermar /trunk/ Support for six syscall arguments for sparc64.
There is a minor stability issue which needs to be fixed (kernel panics upon entering kconsole from the
console task).
 
2510 6177 d 7 h jermar /trunk/kernel/ Experimental support for the cgsix framebuffer, which is found on old Ultra 1
worksations, and the SBUS bus and devices. Not tested.
 
2462 6268 d 7 h jermar /trunk/kernel/ Replace gcc-specific __FUNCTION__ with C99 __func__.
suncc's xregs=no%float can be used only on sparc64.
 
2272 6316 d 9 h jermar /trunk/kernel/ Indentation and formatting fixes.  
2267 6318 d 8 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix indentation.  
2266 6318 d 8 h jermar /trunk/kernel/arch/sparc64/src/mm/ Add few assertions to tsb.c and clean it up a little bit.  
2252 6320 d 6 h jermar /trunk/kernel/arch/sparc64/src/mm/ Move one MEMBAR instruction from a delay slot,
which is, due to SF Erratum #51, a potentionally
dangerous place for a MEMBAR to be.
 
2231 6326 d 11 h jermar /trunk/kernel/arch/sparc64/ Fix a nasty bug in the TLB miss handlers on sparc64.
After we no longer lock the kernel stack in the DTLB,
there is a real danger of nested DTLB misses. The nested
miss can very easily clobber the DTLB Tag Access register.
Therefore, the original miss may not read this register, but
it has to receive its value as an argument. The argument
value is saved in the trap table when it is guaranteed that
the nested TLB miss will not occur.
 
2228 6326 d 13 h jermar /trunk/kernel/arch/sparc64/src/ Fix ticket #28.
In switch_to_userspace(), the uarg argument is in %i2, not in %i3.
 
2227 6326 d 21 h decky /trunk/kernel/ start shutdown infrastructure  
2170 6335 d 5 h jermar /trunk/kernel/ Simplify synchronization in as_switch().
The function was oversynchronized, which
was causing deadlocks on the address
space mutex.

Now, address spaces can only be switched
when the asidlock is held. This also protects
stealing of ASIDs. No other synchronization
is necessary.
 
2161 6337 d 8 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix TSB bug during TSB refill.
When one wants to enable a TSB entry, he or she should set the
entry invalid bit to false, as opposed to setting it to true.
