vt: export RGB offsets with FBIO_GETRGBOFFS Add a new ioctl to vt to make it possible to export RGB offsets set by vt drivers. This is needed to fix colors on X and Mesa on some machines, especially on modern PowerPC64 BE ones. With the appropriate changes in SCFB, to use this ioctl to find out the correct RGB offsets, this fixes wrong colors on Talos II and Blackbird, when used with their built-in video cards.

vt: avoid overrun when stride is not a multiple of bytes per pixel The reporter is developing a frame buffer driver for hardware using 3 bytes per pixel, but a stride that's a multiple of 256. Previously this resulted in writing beyond the end of each stride. On the last row this attempted to write past the end of the frame buffer, triggering the assertion in vt_fb_mem_wr1().

Speed up vt(4) by keeping a record of the most recently drawn character and the foreground and background colours. In bitblt_text functions, compare values to this cache and don't re-draw the characters if they haven't changed. When invalidating the display, clear this cache in order to force characters to be redrawn; also force full redraws between suspend/resume pairs since odd artifacts can otherwise result. When scrolling the display (which is where most time is spent within the vt driver) this yields a significant performance improvement if most lines are less than the width of the terminal, since this avoids re-drawing blanks on top of blanks. (Note that "re-drawing" here includes writing to the VGA text mode buffer; on virtualized systems this can be extremely slow since it triggers a glyph being rendered onto a 640x480 screen). On a c5.4xlarge EC2 instance (with emulated text mode VGA) this cuts the time spent in vt(4) during the kernel boot from 1200 ms to 700ms; on my laptop (with a 3200x1800 display) the corresponding time is reduced from 970 ms down to 155 ms.

sys/dev: further adoption of SPDX licensing ID tags. Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

Support frame buffers that are larger than the default screen size as defined by VT_FB_DEFAULT_WIDTH and VT_FB_DEFAULT_HEIGHT (at this time 2048x1200). The default is really a max. We cap the height and width to those defaults and position the screen in the center of the frame buffer. Ideally we use a bigger font to utility the entire real estate that is the frame buffer, but that's seen as an improvement over making it work first. PR: 193745

Add support for USB display link adapters to the FB and VT drivers.

This change also allows removing the masking of the FB_FLAG_NOMMAP flag in the PS3 syscons driver. The FB and VT drivers were tested using X.org/xf86-video-scfb and syscons.

vt(4): Add support to "downgrade" from eg. vt_fb to vt_vga The main purpose of this feature is to be able to unload a KMS driver. When going back from the current vt(4) backend to the previous backend, the previous backend is reinitialized with the special VDF_DOWNGRADE flag set. Then the current driver is terminated with the new "vd_fini" callback. In the case of vt_fb and vt_vga, this allows the former to pass the vgapci device vt_fb used to vt_vga so the device can be rePOSTed. Differential Revision: https://reviews.freebsd.org/D687

The original patch was provided by Andriy Gapon. This new patch registers the handlers in vt_upgrade(). This is done once, thanks to the VDF_ASYNC flag. I abused this flag because it was already abused by the keyboard allocation. The event handlers then call the backend if it provides callbacks for suspend/resume.

vt(4): Colors are indexed against a console palette, not a VGA palette Rename vt_generate_vga_palette() to vt_generate_cons_palette() and change it to build a palette where the color index is the same than in terminal escape codes, not the VGA index. That's what TCHAR_CREATE() uses and passes to vt(4). The main differences between both orders are: o Blue and red are swapped (1 <-> 4) o Yellow and cyan are swapped (3 <-> 6) The problem remained unnoticed, because the RGB bit indexes passed to vt_generate_vga_palette() were reversed. This inversion was cancelled by the colors inversions in the generated palette. For instance, red (0xff0000) and blue (0x0000ff) have bytes in opposite order, but were swapped in the palette. But after changing the value of blue (see last paragraph), the modified color was in fact the red one. This commit includes a fix to creator_vt.c, submitted by Nathan Whitehorn: fb_cmsize is set to 16. Before this, the generated palette would be overwritte. This fixes colors on sparc64 with a Creator3D adapter. While here, tune the palette to better match console colors and improve the readability (especially the dark blue).
