nat | Avoid adding another member to the softc and use sc_flags instead.
NFCI.
|
| 1.23 |
| 08-Aug-2023 |
nat | Add a flag for output only devices and attachments.
It is necessary to skip the test for the device as output only attached
devices lack the ability for the device to be probed - such as the 1602 lcd
module.
|
| 1.22 |

nat | Add a detach function.
|

uebayasi | Don't pull in the whole uvm(9) API to access only PAGE_SIZE and
some other constants. These are provided by sys/param.h now.

dsl | ANSIfy functions with function-pointer arguments
|

| 14-Mar-2009 |
dsl | ANSIfy another 1261 function definitions.
The only ones left in sys are beyond by sed script!
(or in sys/dist or sys/external)
Mostly they have function pointer parameters.
|
| 1.17 |
| 14-Mar-2009 |
dsl | Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)

Fix some random LCD corruption on cobalt:
- make sure to set HD_ROW1_ADDR before putting characters at the first line
in hd44780_ddram_redraw()
- use memmove(9) rather than bcopy(9) for possibly overlapped copies

jmmv | branches: 1.9.12; 1.9.14; 1.9.18;
Add an extra cookie to the ioctl and mmap wsdisplay accessops that points
to the screen on which they are being called. The driver cannot guess
this by itself but it is needed to implement, at least, the getwschar and
putwschar functions in the correct place. There are no functional changes
yet.
Tested on i386 (vga, vga_raster, machfb, vesafb), macppc and sparc64.
Suggested and reviewed by macallan@.

joff | 4-line HD44780 LCD display support. Work needed for the NetBSD toaster port.
The HD44780 actually doesn't support 4 lines, but the 4 line displays
use two chips, one for the top two lines and one for the bottom
two lines. The chips share the databus, register-select, and write
signals but have separate enable signals.

joff | Handle (i.e. don't lock up the kernel in hd44780_busy_wait) the case of the
LCD not being there.
|
| 1.2 |
| 08-Jan-2005 |
joff | Various improvements for connecting HD44780s using bit-banging style devices
o add sc_writereg and sc_readreg functions that get passed the hd44780_chip
struct and RS (register-select) signal
o add sc_dev to struct hd44780_chip so upper level read/write routines can get
back to their parent softc
o change TIMEOUT_XXX to HD_TIMEOUT_XXX
o remove sc_rread and sc_rwrite in favor of new sc_writereg and sc_readreg
o add new flag HD_UP to sc_flags that is set once 4bit/8bit mode selection
has been finalized.
o remove sc_irwrite, MD readreg/writereg should check state of HD_UP instead

Follow the merge of pmap.c on i386 and amd64 and move
pmap_init_tmp_pgtbl into arch/x86/x86/pmap.c. Modify the ACPI wakeup
code to restore CR4 before jumping back into kernel space as the large
page option might cover that.
