PING sys/dev/videomode: latest DMT and complete Established Timings
Since there are some infelicities in the handling of the resolution of
the framebuffer (10.0_BETA doesn't behave as 9.3), I have started to
review the code, starting from the end: the monitor.
The monitor being the reference, I have replaced the modelines, derived
from XFree86, with the reference: the latest VESA DMT (v 1.0, Rev. 13)
---that is ahead compared to:
/usr/xsrc/external/mit/xorg-server/dist/hw/xfree86/common/vesamodes.
This file is: "dmt".
I have also put modes not found in VESA DMT, but referenced in the
Established Timings, so in VESA EDID, in a file "extradmt".
XFree86 modelines can be easily computed from the DMT. The reverse is
not true. Furthermore there are various VESA identifiers (one, two or
three bytes) that will be used in the future.
It is interesting to note, too, that there are discrepancies between
what is found in the XFree86 modelines and what can be found in the
modelines in the Linux framebuffer code---for one Established Timing
mode, I had to resort to the Linux parameters since what is found in
the XFree86 (at least 10.0 xsrc) is not accurate.
"dmt" replaces "modelines"
"extradmt" is new.
"dmt2c.awk" replaces "modelines2c.awk"
"videomode.c" has to be regenerated using Makefile.videomode.
The remaining diff is adjustements for the new parameters.
For ergonomy and consistancy, I have replaced strings like "800x600x60"
by "800x600@60Hz".
There are now 93 modes instead of 46 (the double scan entries and the
related code weren't used; and this is not used in the present code
either).
For safety, not knowing if this has hardware implications, the new
"reduced blanking" entries are skipped.
This is only a first step and does not solve the problem I see.
The next step will be reviewing and perhaps updating the edid code.
And I will follow the track until I find why the preferences are
not handled correctly from what is passed by the monitor.
Note: this one infelicity, for me, is not severe enough to hinder, per
se, the release of 10.0.

# These values are just the VESA EDID Established timings that are not

#
# They are derived from XFree86:
# xsrc/external/mit/xorg-server/dist/hw/xfree86/modes/xf86EdidModes.c
#
# For one value, the XFree86 file "xf86EdidModes.c" uses 1152x864@75Hz
# instead of the specified 1152x870@75Hz. We derive our parameters,
# instead, for the specified 1152x870@75Hz from the Linux file:
#
# drivers/video/fbdev/macmodes.c
#
# It must be noted that XFree86 and the Linux kernel, at least for
# the other Mac modes, do not agree...
#
# Since the values given do not specify the margins, for a line or a
# frame, and since the GTF doesn't apply (none of the parameters found
# from the above sources correspond to a GTF timing), all margins
# are taken as 0 and the blanking time is all in the porch times.
#
# This does mean that the "specifications" below are definitively _not_
# authoritative and should be taken for what they are worth.

# In a nutshell: everything is given according to the dot clock i.e.
# is expressed in dots.
#
# One must know how long to draw; how long to wait before sending
# the Hor Sync signal; how long to send the sync signal; how long to
# wait before starting to draw again. So these, below, are actually
# times, taking into account that the specification handles chars
# as a unit for horizontal lines, that are eventually defined as a
# number of pixels (dots):
#
# hdisplay: the line addressable length i.e. the H resolution
# hsync_start: hdisplay + H_Right_Border + H_Front_Porch
# hsync_end: hsync_start + Hor_Sync_Time
# htotal: hsync_end + H_Back_Porch + H_Left_Border.
#
# Vertical is not considering lines, but frames. This is homologous:
#
# vdisplay: the vertical addressable length i.e. the V resolution
# vsync_start: vdisplay + V_Bottom_Border + V_Front_Porch
# vsync_end: vsync_start + Ver_Sync_Time
# vtotal: vsync_end + V_Back_Porch + V_Top_Border.
#
# So from the definitions above, per direction, the numbers
# increase.
