1912 6456 d 18 h jermar /trunk/kernel/ Separate mapping of EBUS interrupts into two parts: EBUS and PCI.  
1911 6457 d 6 h jermar /trunk/kernel/ Add support for interrupt mapping in the Sabre PCI controller.
Add support for PCI and EBUS interrupt mapping via the OpenFirmware device tree.
Unfortunatelly, the code is not capable enough to earn single ns16550 interrupt.
I suspect something needs to be enabled in the EBUS registers.
 
1910 6460 d 6 h jermar /trunk/kernel/ Rename INO to INR, for the sake of consistency with manuals.  
1909 6461 d 8 h jermar /trunk/ Extend the OFW device tree node with a void pointer. The boot loader is
supposed to reset all pointers in all nodes. The kernel uses the pointer
to recognize that a particular device has already been visited and initialized.

Read interrupt mapping from the OFW device tree for FHC devices (z8530) and
EBUS devices (ns16550). In case of FHC devices, remove hardwired values from
the code and use only values read from the tree. FHC initialization is started
when a FHC device wants to map its interrupt. In case of EBUS devices, map
the interrupt to INO. Interrupt enabling in the interrupt controller for that
specific interrupt is not implemented yet.
 
1908 6463 d 18 h jermar /trunk/kernel/genarch/ Add function to find OFW tree node by handle.  
1907 6463 d 19 h jermar /trunk/ Add node handle to in-memory ofw tree node.
This is essential for interrupt mapping on sparc64
and perhaps on other platforms that have OpenFirmware.
 
1899 6467 d 16 h jermar /trunk/ sparc64 work:
- Loader now starts all processors.
- Kernel halts all but the bootstrup processor for now.
- Read clock-frequency from the respective processor node in the device tree
 
1898 6468 d 8 h jermar /trunk/kernel/ Support for FFB (Creator 3D) framebuffer detection on sparc64.
(Not tested as the Ultra 60, which I have for testing, and which
only has this type of framebuffer doesn't boot for some unknown reason.)
 
1897 6470 d 16 h jermar /trunk/ Convert sparc64 framebuffer code to configure from the OpenFirmware device tree memory representation.  
1896 6471 d 7 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.
 
1895 6473 d 8 h jermar /trunk/ More ofw_tree work and fixes.
Add ofw_tree_lookup().
Every ofw_tree_node now also contains a disambigued name which is essential for tree lookups.
 
1894 6474 d 6 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 6475 d 7 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).
 
1889 6476 d 9 h jermar /trunk/kernel/ Fix bug in mm/as.c:
- as_area_destroy() should not work with AS but as

sparc64 work:
- start implementing TSB support
 
1888 6479 d 12 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1880 6483 d 8 h jermar /trunk/ Small improvements here and there.  
1875 6486 d 9 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 6487 d 20 h jermar /trunk/ Replace FB_BIG_ENDIAN with FB_INVERT_ENDIAN.
Omit tests for architecture endianness in deciding framebuffer endianness.
 
1869 6488 d 12 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 6503 d 15 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 6507 d 17 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 6513 d 19 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 6515 d 10 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 6515 d 13 h jermar /trunk/kernel/genarch/ Move code duplicated in i8042.c and z8530.c to key.c.  
1842 6515 d 16 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 6515 d 17 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 6520 d 13 h jermar /trunk/kernel/ Add scan code map for Sun keyboard.  
1837 6520 d 21 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 6542 d 11 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 6544 d 11 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1784 6545 d 8 h jermar /kernel/trunk/ Sync OpenFirmware functionality with boot.
Random cleanup.
 
1780 6551 d 12 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1777 6551 d 14 h jermar /kernel/trunk/ Make sparc64 kernel assume it is loaded by our loader.  
1767 6559 d 19 h palkovsky /kernel/trunk/ Remove unneeded FRAME_PANIC.
Fix some things broken by last commit.
 
1766 6559 d 19 h palkovsky /kernel/trunk/ Changed frame_alloc call, cleaned a lot of stuff, fixed some not-perfectly-correct error handling.  
1760 6562 d 13 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 6564 d 21 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 6565 d 17 h jermar /kernel/trunk/ Cleanup of comments.  
1754 6565 d 18 h jermar /kernel/trunk/ Indentation and some improved comments.
Remove forgotten comment from gxemul.sh.
 
1753 6565 d 20 h palkovsky /kernel/trunk/genarch/src/i8042/ Fix bad interrupt handling in kbd driver.
Read all data available on interrupt.
