1875 6504 d 16 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.
 
1871 6506 d 2 h jermar /trunk/ Replace FB_BIG_ENDIAN with FB_INVERT_ENDIAN.
Omit tests for architecture endianness in deciding framebuffer endianness.
 
1869 6506 d 19 h jermar /trunk/ Pass "fb.bpp-align" property to userspace so that our fb task works properly even on
framebuffers used in some Sun hardware.
 
1851 6521 d 22 h jermar /trunk/kernel/ sparc64 work.
Define the istate structure.
Move the identity-mapping handler to assembly.
Make the preemptible handler more general so that TL=1 MMU exceptions can make use of it.

Little bit of formatting and indentation.
 
1849 6526 d 0 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.
 
1848 6532 d 2 h jermar /trunk/kernel/ Rework the z8530 driver so that it is based on z8530 specification rather
than on accidental and limited "compatibility" with i8042.
 
1844 6533 d 17 h jermar /trunk/kernel/ Add an option to compile the sparc64 kernel for Ultra 5 or Enterprise E6500.
Basic keyboard support (polling) based on ns16550 serial port (deployed on Ultra).
 
1843 6533 d 19 h jermar /trunk/kernel/genarch/ Move code duplicated in i8042.c and z8530.c to key.c.  
1842 6533 d 22 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 6533 d 23 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.
 
1838 6538 d 20 h jermar /trunk/kernel/ Add scan code map for Sun keyboard.  
1837 6539 d 3 h jermar /trunk/ Support 24bpp framebuffers with 4 pixelbytes (each pixel aligned on 32-bits).

At least on sparc64, the OpenFirmware linebytes property specifies the number
of pixels between consecutive scan lines of the display. Fix scanilne calculation,
including possible alignment.

Add note to 8bpp pixel functions pointing out drawbacks of that mode.
 
1790 6560 d 18 h jermar /trunk/ Remove OpenFirmware calls from kernel/ entirely.

Switch the sparc64 port to use bootinfo.

Copy memcpy from boot/ to sparc64 kernel/ and
adjust it for memcpy_from/to_uspace.
 
1787 6562 d 17 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1784 6563 d 15 h jermar /kernel/trunk/ Sync OpenFirmware functionality with boot.
Random cleanup.
 
1780 6569 d 18 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1777 6569 d 21 h jermar /kernel/trunk/ Make sparc64 kernel assume it is loaded by our loader.  
1767 6578 d 1 h palkovsky /kernel/trunk/ Remove unneeded FRAME_PANIC.
Fix some things broken by last commit.
 
1766 6578 d 1 h palkovsky /kernel/trunk/ Changed frame_alloc call, cleaned a lot of stuff, fixed some not-perfectly-correct error handling.  
1760 6580 d 19 h palkovsky /kernel/trunk/ Changed interface of frame_alloc/free to use address of frame instead of the pfn.
This makes it impossible to use >4GB of memory on 32-bit machines, but who cares...
 
1759 6583 d 4 h palkovsky /kernel/trunk/genarch/src/i8042/ Disable mouse on entry to kconsole. If it doesn't help
(like in qemu, which still generates mouse data), we would have
to let it enabled and filter out the mouse data.
 
1757 6583 d 23 h jermar /kernel/trunk/ Cleanup of comments.  
1754 6584 d 0 h jermar /kernel/trunk/ Indentation and some improved comments.
Remove forgotten comment from gxemul.sh.
 
1753 6584 d 2 h palkovsky /kernel/trunk/genarch/src/i8042/ Fix bad interrupt handling in kbd driver.
Read all data available on interrupt.
 
1735 6586 d 1 h decky /kernel/trunk/ make kernel prints case consistent  
1708 6588 d 0 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 6590 d 0 h cejka /kernel/trunk/ Added file with modules definitions and descriptions.
We are able to change modules order and their description in one place.
 
1704 6590 d 3 h cejka /kernel/trunk/ Fixed first letter size of subgroup name in Others.  
1702 6590 d 21 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1690 6593 d 15 h palkovsky /kernel/trunk/ Yet another fix with framebuffer.  
1683 6594 d 2 h jermar /kernel/trunk/genarch/src/fb/ Pass correct yres to userspace framebuffer.  
1682 6594 d 4 h palkovsky /kernel/trunk/ Fast framebuffer scrolling in kconsole. Eats some memory though.  
1671 6595 d 14 h jermar /kernel/trunk/genarch/src/fb/ Eliminate deadlock condition from fb.  
1637 6597 d 11 h jermar /kernel/trunk/genarch/src/mm/ Improve comment.  
1636 6597 d 11 h jermar /kernel/trunk/ Move comment.

Do TLB shootdown also when allocating new ASID.
 
1474 6603 d 13 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1473 6603 d 16 h decky /kernel/trunk/ kernel support for text-only framebuffer  
1468 6603 d 19 h jermar /kernel/trunk/ Function for destroying address space for which there is no other reference in the kernel.  
1424 6607 d 18 h jermar /kernel/trunk/ Move the sharing functionality to address space area backends.
Add backend for continuous regions of physical memory.
Sharing for these areas works automagically now.
 
1423 6607 d 22 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.
