Summary: Nouveau doesn't allow my modeline because of hardcoded
value
Product: xorg
Version: git
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: Driver/nouveau
AssignedTo: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
ReportedBy: a.j.buxton-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org
QAContact: xorg-team-go0+a7rfsptAfugRpC6u6w@public.gmane.org
in nv_output.c line 344:
if (mode->Clock < 12000)
return MODE_CLOCK_LOW;
This code prevents the following modeline from working:
ModeLine "512x288pal" 9.875 512 528 576 632 288 290 293 311 -hsync -vsync
Reducing the value 12000 allows it to work. I use this modeline with a VGA to
SCART adapter, a small passive adapter (just two transistors to generate
composite sync) which allows a normal television with RGB inputs to be
connected directly to the analogue VGA connector.

What other driver does this modeline work with? I doubt it works with nv.
If you're using this successfully with the nvidia binary driver I'd like to see
what PLL setup they arrive at. To do this, please do "git clone
git://anongit.freedesktop.org/~stuart/radeontool", then make, then dump some
regs as follows (while in X, with this mode set up, running the binary driver):
./radeontool regmatch 0x101000
./radeontool regmatch 0x680508
if your card is nv11 (geforce 2 mx) or newer please also do
./radeontool regmatch 0x680520
if your card is nv31 (geforce fx 5xxx) or newer please also do
./radeontool regmatch 0x680578
./radeontool regmatch 0x68057c
and if your card is nv41 (geforce 6xxx) or newer please also do
./radeontool regmatch 0x680580
and attach the values read (looks like "0x680580 0x00011e07 (73223)") as

01:00.0 VGA compatible controller: nVidia Corporation NV18 [GeForce4 MX 4000]
(rev c1)
0x680520 0x00045405 (283653)
The modeline does work successfully with nouveau after removing the quoted
sanity check or reducing the value. The output from radeontool is identical for
both nvidia and patched nouveau.
nv does not support this modeline; it also arbitrarily sets the minimum clock
frequency to 12000

Hi, can I also have ./radeontool regmatch 0x101000 and ./radeontool regmatch
0x680508 while running this mode under nvidia. An Xorg.0.log to show what's
getting set would also help (and if you can run Xorg with "-logverbose 9"
that's even better).

Also, 9.875 mhz is not even the lowest pixel clock somebody might want to use.
That modeline is 16:9 - the 4:3 equivalent (384x288) would have a pixel clock
of 7.375 mhz.

Yeah, seems this restriction was pretty arbitrary in the old driver, so now it
accepts all clocks (which works until the pll calculator craps out; ~6.25MHz
for two stage plls, < 0.25MHz for single stage).
