src/sys/dev/syscons/scvidctl.c, branch releng/10.2

Add tty_set_winsize().

2012-11-03T22:21:37Z

This removes some of the signalling magic from the Syscons driver and puts it in the TTY layer, where it belongs.

Clean up code a bit to make it more readable.

Refine r204265. We want the standard VGA palette for packed pixel mode.

2010-03-29T22:41:30Z

Improve VESA mode switching via loader tunable `hint.sc.0.vesa_mode'.

2010-02-24T20:13:34Z

The most notable change is history buffer is fully saved/restored now.

Yet another attempt to make palette loading more safer:

2010-02-23T21:51:14Z

- Add a separate palette data for 8-bit DAC mode when SC_PIXEL_MODE is set and fill it up with default gray-scale palette data for text. Now we don't have to set `hint.sc.0.vesa_mode' to get the default palette data. - Add a new adapter flag, V_ADP_DAC8 to track whether the controller is using 8-bit palette format and load correct palette when switching modes. - Set 8-bit DAC mode only for non-VGA compatible graphics mode.

Fix pgsignal() call after signature change in r199355.

Integrate the new MPSAFE TTY layer to the FreeBSD operating system.

2008-08-20T08:31:58Z

The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following: - Improved driver model: The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers. If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

Replace explicit calls to video methods with their respective variants

2007-12-29T23:26:59Z

implemented with macros. This patch improves code readability. Reasoning behind vidd_* is a sort of "video discipline". List of macros is supposed to be complete--all methods of video_switch ought to have their respective macros from now on. Functionally, this code should be no-op. My intention is to leave current behaviour of touched code as is. No objections: rwatson Silence on: freebsd-current@ Approved by: cognet

Fix our ioctl(2) implementation when the argument is "int". New

2006-09-27T19:57:02Z

ioctls passing integer arguments should use the _IOWINT() macro. This fixes a lot of ioctl's not working on sparc64, most notable being keyboard/syscons ioctls. Full ABI compatibility is provided, with the bonus of fixing the handling of old ioctls on sparc64. Reviewed by: bde (with contributions) Tested by: emax, marius MFC after: 1 week
