Hello,
The latest PM branch is now available[1].
I've done basic testing of retention and off-mode (suspend and dynamic
idle) on Beagle and custom HW. My SDP has something still keeping
CORE active that others have not seen, but I have yet to debug. Any
other reports from SDP testing would be appreciated.
Notable changes/updates
- rebased on latest clock updates and fixes from Paul
- clockfw pre- and post- notifiers
- DVFS for VDD2
Full git shortlog below[2]
Enjoy,
Kevin

A better way to write that, in recent kernels, is if (WARN(!clk->clkdm.name, "clock: %s missing clockdomain\n", clk->name)) return -EINVAL; Where "better" includes "diagnostic message is always present" and thus "line numbers matter less".

This patch made it in before v2.6.28-omap1 which the latest PM branch is based on, so I'm guessing you're not testing the latest PM branch.

Sriram, Can you send me your .config for omap3evm? I'm trying to get my recently received EVM working but I am getting lots of garbage on the serial console on linux-omap HEAD and PM branch on omap3evm. Do you have any additional patches for EVM that you're using?

This should not prevent retention. I see this on beagle as well, and it doesn't prevent retention. From the log below, you didn't copy the part which reports whether all domains hit target state.

It's just sleeping, but refuses to wakeup (like I should've done this morning.) What are you using as your wakeup source? UART? keypad? I'm not sure how the UARTs are mux'd on this board, but you probably want to check the wake-enable bits in the padconf reg for the UART pins. This is done by arch/arm/mach-omap2/serial.c but assumes the UARTs are mux'd using the default registers. Each UART has a couple possible ways to be mux'd. > After sending the last mail, I tried the same without enabling "clocks_off_while_idle" and "sleep_while_idle" then: > > omapfb omapfb: timeout waiting for FRAME DONE > Powerdomain (core_pwrdm) didn't enter target state 1 > Powerdomain (per_pwrdm) didn't enter target state 1 > Could not enter target state in pm_suspend > I am building a config without FB.

If youre seeing junk after a certain point while booting. it could be related to your bootargs console options. (console=ttyS0,115200n8) 2) Sometimes i do get the usual omapfb errors. 3) If i enable cpuidle - the ethernet driver is unable to get an IP address. So it is unable to mount NFS. If i give a statically assigned IP in my bootargs. NFS mount also fails. This happens only when cpuidle is enabled. 4) If i enable SMC debug, i see ethernet interrupts happening, for some reason. NFS mount/getting a dhcp address fails. I am not sure if this is a wakeup issue. Sometimes, if i add some debug prints it works. but this does not work every time. 5) If i boot with rootfs on MMC and with cpu idle enabled. i cannot ping. cpuidle is somehow effecting the network stuff. I also see some rx overruns. is this a wakeup issue?

(console=ttyS0,115200n8) I have the same console= bootargs. Are you testing on an ES3 EVM? What version of the bootloader to you have?

I also see some rx > overruns. is this a wakeup issue? I have not done any testing with ethernet, only initramfs or MMC rootfs. This is indeed a wakeup issue. The GPIO IRQ for smc91x is not currently set as a wakeup source, so ethernet activity will not wakeup the system, thus causing delays and other problems. Can you try with rootfs on MMC, but with no ethernet (add ip=none to cmdline.) Then try suspend/resume etc. Kevin > On Wed, Jan 14, 2009 at 10:09 PM, Kevin Hilman > <khilman@deeprootsystems.com <mailto:khilman@deeprootsystems.com>> wrote: > > Sriram V wrote: > >> > >> Hi, > >> OMAP3EVM. all domains hit retention in suspend. > >> > >> On enabling cpuidle, network and mmc is not stable. network is > >> unable to get an IP address. > > > > Sriram, > > > > Can you send me your .config for omap3evm?

Looking at the registers, I am pretty sure it is the D2D clockdomain that still has activity, but due to very poor Stacked-mode docs and no responses to the D2D questions asked to TI I have not been able to figure this one out. Help debugging this would be greatly appreciated. > Further doing a > echo -n 1 > /sys/power/sleep_while_idle causes a hang after the 5 odd secs > of UART inactivity. > Is'nt this option supposed to affect only the suspend path behavior?

I looked some more into this today and saw that the hang is indeed caused due to some kind of debug console going dead. The system was still looping in the idle thread. I could even do a telnet remotely to my board and take some debug dumps.. I am not too familiar with the debug hooks that exist but from what I understand, IVA seem to be one thing preventng a RET/OFF. This dump I took from a telnet window after the hang on debug console.. # cd pm_debug/ # cat count usbhost_pwrdm (RET),OFF:0,RET:1,INA:0,ON:1 sgx_pwrdm (OFF),OFF:1,RET:0,INA:0,ON:1 per_pwrdm (ON),OFF:0,RET:0,INA:0,ON:1 dss_pwrdm (RET),OFF:0,RET:1,INA:0,ON:1 cam_pwrdm (RET),OFF:0,RET:1,INA:0,ON:1 core_pwrdm (ON),OFF:0,RET:0,INA:0,ON:1 neon_pwrdm (ON),OFF:0,RET:466,INA:3048,ON:3515 mpu_pwrdm (ON),OFF:0,RET:466,INA:3048,ON:3515 iva2_pwrdm (ON),OFF:0,RET:0,INA:0,ON:1 per_clkdm->per_pwrdm (9) usbhost_clkdm->usbhost_pwrdm (0) cam_clkdm->cam_pwrdm (0) dss_clkdm->dss_pwrdm (0) core_l4_clkdm->core_pwrdm (3) core_l3_clkdm->core_pwrdm (4) d2d_clkdm->core_pwrdm (0) sgx_clkdm->sgx_pwrdm (0) iva2_clkdm->iva2_pwrdm (0) neon_clkdm->neon_pwrdm (0) mpu_clkdm->mpu_pwrdm (0) prm_clkdm->wkup_pwrdm (12) cm_clkdm->core_pwrdm (3) # Whats surprsing is that the same image sometimes does hit RET/OFF, though I still see the console hang.

Thanks Jouni. I now have this queued up for pm branch. Indeed beagle and custom hw I'm using are not using UART1, that's why I didn't notice before. This is probably causing the non-wakeup problem on EVM as well. Will try today.

Looks like the errata implementation done as part of the omap3_iva_idle is needed only on silicon rev's 1.0 and 2.0. On my ES3.0 *not* doing that is helping me hit RET/OFF in idle and suspend. Not sure if this is an expected behaviour or some changes are needed in the errata fix sequence. I'll try finding out more on that. But for now, not doing the errata fix helps me hit CORE RET/OFF on my ES3.0SDP. > > > Not sure why this was affecting only the SDP while the pm > branch seems > > to function without this for beagle and other omap3 platforms? > > > >> > >> diff --git a/arch/arm/mach-omap2/pm34xx.c > >> b/arch/arm/mach-omap2/pm34xx.c > >> index b2db0ba..266e4f5 100644 > >> --- a/arch/arm/mach-omap2/pm34xx.c > >> +++ b/arch/arm/mach-omap2/pm34xx.c > >> @@ -401,6 +401,8 @@ void omap_sram_idle(void) > >> omap3_prcm_restore_context(); > >> omap3_sram_restore_context(); > >> } > >> + omap_uart_resume_idle(0); > >> + omap_uart_resume_idle(1); > >> if (core_next_state == PWRDM_POWER_OFF) > >> prm_clear_mod_reg_bits(OMAP3430_AUTO_OFF, > >> OMAP3430_GR_MOD, > >> > >> -- > >> Jouni Högander > >> > >> > >> > > -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html ^ permalink raw reply [flat|nested] 40+ messages in thread

Some domains (core, per, dss) stay on, but even mpu > and neon don't go to retention. They only go to inactive. A first guess: this sounds like CONFIG_OMAP_RESET_CLOCKS=y is missing from your .config. The MPU/NEON going active but not RET is an indication to me that some fclk is active so that the fclk check in omap3_can_sleep() fails, so a WFI is never attempted. That's shy Personally, I'm thinking we should totally drop this fclk check. I see no reason not to attempt a WFI, even if there are active fclks. > So could you send your .config file ? Attached. > Which rootfs are you using, I'm using debian, so maybe something > keeps the CPU busy. Are you using NAND or MMC to store your rootfs ? I'm using rootfs on MMC and have tested with busybox-only, debian and OE rootfs. With debian and OE, I usually boot a minimal rootfs, before a full userland comes up. With debian, I changed my /etc/init.d/rcS to start initlevel 1 instead of 'S'. > Which beagle HW rev do you have ? I'm testing on a B5 board. I have a rev B4. > And which u-boot are you using ? I'm using the u-boot from Steve Sakoman's tree[1]. That helped a lot in my initial Beagle testing, but I think the kernel should reset the IVA and D2D now which is the domains that I was having problems with before, so I think that the out of the box u-boot should work fine.

That's shy > Ok. I did enable CONFIG_OMAP_RESET_CLOCKS. But with your config file only PER and CORE did not go to retention. One difference is that I did not enable smartreflex, but as B5 (and B4) are using OMAP3s without proper efuse values, smartreflex shouldn't matter I assume ? I upgrade my u-boot to the latest version, and then PER went to retention as well. The only way to get core to retention was to force idle USBOTG and disable the USBOTG driver. Dynamic retention seems to work only once the system has been in static retention once. Static off mode seems to work, but resume from off kills the UART.

Did you happen to notice what was keeping PER out of retention before the u-boot upgrade? Looks like we might still need some init-time reset code to compensate for bootloaders. > The only way to get core to retention was to force idle USBOTG and > disable the USBOTG driver. This is the same issue on 3430SDP. The PM branch code does the force-idle, and I usually have USB built as modules and not loaded when I do the tests. I'm guessing this is a result of u-boot configuring/using USB. > Dynamic retention seems to work only once the system has been in static > retention once. > > Static off mode seems to work, but resume from off kills the UART.

I haven't looked at all at the T2 scripts being used on Beagle. Do you think some of these issues may be related to those scripts?
