* Various fixes for PCI _OSC handling so HotPlug works again.John Baldwin2017-04-274-16/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Rename the default implementation of 'pcib_request_feature' and add a pcib_request_feature() wrapper function (as is often done for new-bus APIs implemented via kobj) that accepts a single function. Previously the call to pcib_request_feature() ended up invoking the method on the great-great-grandparent of the bridge device instead of the grandparent. For a bridge that was a direct child of pci0 on x86 this resulted in the method skipping over the Host-PCI bridge driver and being invoked against nexus0 - When invoking _OSC from a Host-PCI bridge driver, invoke device_get_softc() against the Host-PCI bridge device instead of the child bridge that is requesting HotPlug. Using the wrong softc data resulted in garbage being passed for the ACPI handle causing the _OSC call to fail. - While here, perform some other cleanups to _OSC handling in the ACPI Host-PCI bridge driver: - Don't invoke _OSC when requesting a control that has already been granted by the firmware. - Don't set the first word of the capability array before invoking _OSC. This word is always set explicitly by acpi_EvaluateOSC() since it is UUID-independent. - Don't modify the set of granted controls unless _OSC doesn't exist (which is treated as always successful), or the _OSC method doesn't fail. - Don't require an _OSC status of 0 for success. _OSC always returns the updated control mask even if it returns a non-zero status in the first word. - Whine if _OSC ever tries to revoke a previously-granted control. (It is not supposed to do that.) - While here, add constants for the _OSC status word in acpivar.h (though currently unused).

In the case of NATM we support no devices manufactured in the last 20 years and some will not even work in modern motherboards (some newer devices that patm(4) could be updated to support apparently exist, but we do not currently have support). With this change, support remains for some netgraph modules that don't require NATM support code. It is unclear if all these should remain, though ng_atmllc certainly stands alone. Note well: FreeBSD 11 supports NATM and will continue to do so until at least September 30, 2021. Improvements to the code in FreeBSD 11 are certainly welcome.

* Change the drawing method for the mouse cursor in planar mode to supportBruce Evans2017-04-231-11/+33
| | | | | | | | | | | | | | | | | | colors. Colors are still hard-coded as 15 (normally lightwhite) for the interior and 0 (normally black) for the border, but these are now values used in 2 expressions instead of built in to the algorithm. The algorithm used a fancy and/or method, but this gives no control over the colors except and'ing all color planes off gives black and or'ing all color planes on gives lightwhite. Just draw the border and interior in separate colors using the same method as for characters, including its complications to optimize for VGA adaptors. Optimization is not really needed here, but for the VGA case it avoids being slower than the and/or method. The optimization is worth about 30%. Notes: svn path=/head/; revision=317334

* Merge the main ega drawing method into the main vga planar method andBruce Evans2017-04-211-67/+18
| | | | | | | | | | | | | | | | | remove the former. All other EGA/VGA methods were already shared, with VGA-only features mostly not used and no decisions in inner loops to optimize fof VGA, but this method was split up because it is the only important one and using VGA methods if possible is about twice as fast. The speed is mostly not from splitting to reduce branches but from doing half as many bus accesses, so make this easier to maintain by not splitting. There is now 1 extra branch in an inner loop where it costs less than 1% of the bus access overhead on Haswell even if the compiler schedules it poorly. Notes: svn path=/head/; revision=317256

The vga method doesn't work on ega. Optimize the main vga planar method a little. For changing the background color (which was otherwise optimized better than most things), don't switch the write mode from 3 to 0 just to select the pixel mask of 0xff obscurely by writing 0.

* When the character width is 9, remove vertical lines in the mouse cursorBruce Evans2017-04-202-8/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | corresponding to the gaps between characters. This fixes distortion of the cursor due to expanding it across the gaps. Again for character width 9, when the cursor characters are not in the graphics range (0xb0-0xdf), the gaps were always there (filled in the background color for the previous char). They still look strange, but don't cause distortion. When the cursor characters are in the graphics range, the gaps are filled by repeating the previous line. This gives distortion with cilia. Removing vertical lines reduces the distortion to vertical cilia. Move the default for the cursor characters out of the graphics range. With character width 9, this gives gaps instead of distortion and other problems. With character width 8, it just fixes a smaller set of other problems. Some distortion and other problems can be recovered using vidcontrol -M. Presumably the default was to fill the gaps intentionally, but it is much better to leave gaps. The gaps can even be considered as a feature for text processing -- they give sub-pointers to character boundaries. The other problems are: (1) with character width 9, characters near the cursor are moved into the graphics range and thus distorted if any of their 8th bits is set; (2) conflicts with national characters in the graphics range. The default range for the graphics cursor characters is now 8-11. This doesn't conflict with anything, since the glyphs for the characters in this range are unreachable. Use the 10x16 mouse cursor in text mode too (if the font size is >= 14). When the character width is 9, removal of 1 or 2 vertical lines makes 10x16 cursor no wider than the 9x13 one usually was. We could even handle cursors 1 pixel wider in 2 character cells and gaps without more clipping than given by the gaps (the worst case is 1 pixel in the left cell, 1 removed in the middle gap, 8 in the right cell and 1 removed in the right gap. The pixel in the right gap is removed so it doesn't matter if it is in the font). When the character width is 8, we now clip the 10-wide cursor by 1 pixel in the worst case. This clipping is usually invisible since it is of the border and and the border usually merges with the background so is invisible. There should be an option to use reverse video to highlight the border and its tip instead of the interior (graphics mode can do better using separate colors). This needs the 9x13 cursor again.

This is complicated because there are no standard parameter tables giving this bit of information directly, and the device register bit giving the information can't be trusted even if it is read from the hardware. Use a heuristic to guess if the device register can be trusted. (The device register is normally read from the BIOS mode table, but on my system where the device register is wrong, the mode table doesn't match the hardware and is not used; the device registers are used in this case.)

* Fix missing support for drawing the mouse cursor in depth 24 of directBruce Evans2017-04-191-46/+6
| | | | | | | | | | | | | | | | | | | | | | | mode. Use the general DRAWPIXEL() macro with its bigger case statement (twice) instead of our big case statement (once). DRAWPIXEL() is more complicated since it is not missing support for depth 24 or complications for colors in depth 16 (we currently hard-code black and white so the complications for colors are not needed). DRAWPIXEL() also does the bpp calculation in the inner loop. Compilers optimize DRAWPIXEL() well enough, and the main text drawing method always depended on this. In direct mode, mouse cursor drawing is now similar to normal text drawing except it draws in 2 hard-coded colors instead of 1 variable color. This also fixes a nested hard-coding of colors. DRAWPIXEL() uses the palette in all cases, but the direct code didn't use the palette for its hard-coded black. This only had an effect in depth 8, since changing the palette is not supported in other depths. Notes: svn path=/head/; revision=317157
* Stop using a saveunder method for mouse cursor drawing in the vgaBruce Evans2017-04-191-49/+5
| | | | | | | | | | | | | | | | | | | | | direct mode renderer. I thought that reads were not much slower than writes, so that the method only tripled the time for the whole function, but I recently measured that video memory reads can be up to 53 times slower than writes in tighter loops than here. Loop overheap here reduces the multiplier to only 16-20 on Haswell. Start cleaning up and fixing larger bugs in this function. Only replace the 22-line removal loop by a 3-line one for now, since adjusting the old loop would have required many palette calculations which are better done in the DRAW_PIXEL() macro. This also fixes missing support for depth 24, but only for removal. Removal is currently sloppy at the right bottom corner. It sometimes leaks border color into the text window. This is soon cleaned up by the caller. The planar renderer has complications to clip at the corner. Notes: svn path=/head/; revision=317150
* When we don't use the parameter table in the BIOS, also don't use mostBruce Evans2017-04-191-5/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | of our tweaked modes based on it. In practice, this means limiting the tweaked modes to at most 80x50 based on 80x25, so there are no 90-column, 80x30 or 80x60 modes. This happens when the the initial mode is is not in the parameter table. We always detected this case, but assumed that the (necessarily nonstandard) parameters of the initial mode could be tweaked just as blindly as the probably-standard parameters of initial modes in the table. On 1 laptop system with near-VGA where the initial mode is nonstandard, this is because the hardware apparently doesn't support 9-bit mode, but otherwise has standard timing. The initial mode has 8-bit mode CRTC horizontal parameters similar to those in syscons' 90-column modes and in EGA modes. Tweaking these values for the 90-column modes has little effect except to print the extra 10 columns off the screen. Tweaking from 80x25 to 80x30 requires changing from 400 scan lines to 480. This can probably be made to work, but syscons blindly applies values based on standard timing. This gives blank output. Tweaking from 80x25 to 80x50 doesn't change the CRTC timing and works.
