Sync. pixel mode support for syscons(4) with HEAD. - Separate 24-bit pixel draw from 32-bit case. Although it is slower, we do not want to write a useless zero to inaccessible memory region. - We only want the dummy palette for direct color mode.

MFC r204248,r204249 - "fancy snake_saver" with color coded load averages

MFC x86emu/x86bios emulator and make previously i386 only dpms and vesa

2010-03-02T01:56:55Z

framebuffer driver, etc. work on FreeBSD/amd64. A significant amount of improvements were done by jkim@ during the recent months to make vesa(4) work better, over the initial code import. This work is based on OpenBSD's x86emu implementation and contributed by paradox and swell.k at gmail com. Hopefully I have stolen all their work to 8-STABLE :) All bugs in this commit are mine, as usual.

MFC r199355:

Add SI_KERNEL. MFC r199418: Fix pgsignal() call after signature change in r199355.

MFC various commits back to stable/8:

2009-11-01T10:30:30Z

SVN r197174: Make sure we never place the cursor outside the screen. For some vague reason, it may be possible that scp->cursor_pos exceeds scp->ysize * scp->xsize. This means that teken_set_cursor() may get called with an invalid position. Just ignore the old cursor position in this case. Reported by: Paul B. Mahol SVN r198213: Make lock devices work properly. It turned out I did add the code to use the init state devices to set the termios structure when opening the device, but it seems I totally forgot to add the bits required to force the actual locking of flags through the lock state devices. Reported by: ru SVN r198215, r198217: Fix a typo in the jail(8) manpage. Submitted by: Jille Timmermans SVN r198216: Fix qouting in a comment, to make it look more consistent Submitted by: Jille Timmermans SVN r198223: Properly set the low watermarks when reducing the baud rate. Now that buffers are deallocated lazily, we should not use tty*q_getsize() to obtain the buffer size to calculate the low watermarks. Doing this may cause the watermark to be placed outside the typical buffer size. This caused some regressions after my previous commit to the TTY code, which allows pseudo-devices to resize the buffers as well. Reported by: yongari, dougb

MFC 197062:

2009-09-14T16:13:12Z

Don't malloc a buffer while holding the prison0 mutex. Instead, use a loop where we figure out the hostname length under the lock, malloc the buffer with the lock dropped, then recheck the length under the lock and loop again if the buffer is now too small. Approved by: re (kib)

Small fixes to Unicode handling:

2009-06-16T14:55:13Z

- Add more mappings for Greek characters and the Euro sign. - Print UTF-8 characters in the log file as hexadecimal.

Add more entries to the Unicode-to-CP437 table.

2009-06-14T12:04:34Z

Characters between 0x07 and 0x0d are now also mapped, which means we can display almost 256 different characters. Also remap certain types of dashes and quotes, which means we can finally read our manual pages without red question marks in them. Submitted by: Christoph Mallon

Rename the host-related prison fields to be the same as the host.*

2009-06-13T15:39:12Z

parameters they represent, and the variables they replaced, instead of abbreviated versions of them. Approved by: bz (mentor)

Make the proof-of-concept UTF-8 support in Syscons less useless.

2009-06-13T12:23:31Z

Add a small Unicode-to-CP437 remapping table to at least demonstrate that the terminal emulator is perfectly capable of handling UTF-8. This will of course break if the user loads a different font map, but it at least allows people to give it a try. I can now see the box drawing in dialog(1) and the arrows in mutt(1) correctly.
