It is probably a misconfiguration from my side.

We only want it called for sh7372 though. If you look at other SoC-specific code then you will notice that initcalls are only used for functions in mach-shmobile/ that are common for all SoCs implemented under mach-shmobile. You most likely want to initialize from sh7372_pm_init(), but for that to work you probably have to reorder your code inside mackerel_init().

It should be possible to do that. Do I understand it correctly that you want one structure definition per power domain instead of the two? > I suspect so since these two data types seem to be linked together. > I guess container_of() can be used for conversion between the types?

OK, I'll figure out how to do the initialization correctly.

Thanks, I can trigger using sysfs and your kernel configuration. However, I assumed it also would work when the sceen saver kicked in. I recall it being fbcon that controls the screen save, perhaps something else. So just wait a bit and see if you also can reproduce it. The console gets black but the power is still on... Also forcing to go back to powered-on state (see below) doesn't work that well: # echo 0 > /sys/devices/platform/sh_mobile_lcdc_fb.0/graphics/fb0/blank It looks like we loose the panning information somehow. Most likely a LCDC driver bug. Unless the driver callbacks are not being invoked as expected. Also, there is garbage in on the screen if FB_SH_MOBILE_MERAM is enabled. The MERAM hardware is a 1.5 MiB memory block that can be used as a LCD cache. It sits in the same hardware power domain as the LCDCs. I don't think the MERAM software supports power down unfortunately. Disabling MERAM support removes the garbage on the screen. >> Here's some feedback on the sh7372-specific code: >> >> > --- linux-2.6.orig/arch/arm/mach-shmobile/Kconfig >> > +++ linux-2.6/arch/arm/mach-shmobile/Kconfig >> > @@ -19,6 +19,7 @@ config ARCH_SH7372 >> > select CPU_V7 >> > select SH_CLK_CPG >> > select ARCH_WANT_OPTIONAL_GPIOLIB >> > + select PM_GENERIC_DOMAINS >> >> We want to support a single ARM binary for multiple boards, > > Surely CONFIG_ARCH_SH7372 will be set in that binary? > >> so this should be enabled for all SoCs in mach-shmobile as a whole. > > OK, where exactly do you want me to move it?

Yes, at least that's what I would do to keep the data together.

I noticed that, but I think it simply means pm_runtime_put() isn't called in that code path. > Also forcing to go back to powered-on state (see below) doesn't work that well: > # echo 0 > /sys/devices/platform/sh_mobile_lcdc_fb.0/graphics/fb0/blank > > It looks like we loose the panning information somehow.

That's because, by default, the VT layer will use FB_BLANK_NORMAL mode when blanking the console. Switching that to FB_BLANK_VSYNC_SUSPEND, FB_BLANK_HSYNC_SUSPEND or FB_BLANK_POWERDOWN with TIOCLINUX(TIOC_SETVESABLANK) results in the device being runtime-suspended when the console is blanked. > Also forcing to go back to powered-on state (see below) doesn't work that > well: # echo 0 > > /sys/devices/platform/sh_mobile_lcdc_fb.0/graphics/fb0/blank > > It looks like we loose the panning information somehow.

The MERAM hardware is a 1.5 MiB memory block that can be used > as a LCD cache. It sits in the same hardware power domain as the > LCDCs. I don't think the MERAM software supports power down > unfortunately. Disabling MERAM support removes the garbage on the > screen.
