With the latest PM branch, I've notice that off-while idle isn't working on the SDP, but the same kernel works fine on the RX51. RET-while-idle works fine on both. This is with CPUidle disabled, so just using the default idle where MPU and CORE are changed together. More specifically, it seems to be the UART1 (CORE) console that never comes back from off-while-idle, but the UART3 (PER) console on RX51 works. On SDP, if I # echo 1 /sys/power/enable_off_mode # echo 1 /sys/power/voltage_off_while_idle # echo 1 /sys/power/sleep_while_idle After the UART inactivty timeout of 5 seconds, I start to see the sys_off_mode LED toggling between red and green with system timer wakeups. If I then push a key on the UART1 console, the LED goes green, stays for the 5 second UART inactivity and then goes back to toggling red/green again. However, I never get my console back and never see the characters on my console. If I keep typing, I keep the system from going back off (based on sys_off_mode LED) and as soon as I stop typing long enough for the inactivity timer to expiere (5 seconds) it goes back into off. Any ideas what's going on here? On RX51, the same thing works using UART3.

Re: MUSB ISSUE on OMAP3530 with USB-2-Ethernet converter

The ASIX AX88772A USB2.0 Fast Ethernet Network Adapter Linux driver available in Asix website supports only upto Linux 2.6.26. I integrated that driver into the git kernel and tested it on the OMAP35xx dev board (EHCI port). The driver detects the presence of USB-2-Ethernet converter and it is possible to assign ip address to the new Ethernet interface. But the ping test fails (ping statistics --- 40 packets transmitted, 0 packets received, 100% packet loss) and therefore I cant continue testing it on the latest git kernel. That worked OK for me the last time I hooked up one of those adapters to a 3430 (essentially the same as a 3530). Any help towards solving this issue will be highly appreciated.

Side note is this cost around 1mW of power during active mode of MUSB. When device is not active cost is not significant. System impact depends on duty cycle of MUSB in usecase. There's also some initialization goofiness in that code ... it's supposed to set initialize the transceiver with several distinct writes, of which setting AUTOIDLE (to auto-gate the L3 clock) is ISTR the last step. The goofiness shows up with OTG initialization, which is documented as needing a slightly different sequence ... my notes have it as being an extra write to set ENABLEFORCE. - Dave -- To unsubscribe from this list: send the line unsubscribe linux-omap in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html -- - Niilo Minkkinen Kalhontie 69C 40950 MUURAME +358407324526 niilo.minkki...@iki.fi Arvokkainta ihmiselle on vapaus tehdä omia päätöksiä, jotka ovat joskus vääriäkin - Gottfried Leibniz (1646–1716) - -- -- To unsubscribe from this list: send the line unsubscribe linux-omap in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
Missing OMAP nand drivers from 2.6.30?
Looking at the current linux-omap tree from yesterday, I'm wondering where the NAND chip driver for the OMAP34x/35x is. It used to be in drivers/mtd/nand/omap2.c, but there's no trace of it now (that I can find). Any ideas where it went? -- Peter Barada pet...@logicpd.com Logic Product Development, Inc. -- To unsubscribe from this list: send the line unsubscribe linux-omap in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Arun, Thanks, it's good to hear not only me having this problem ;). So what is the current status of your osk driver? What tree do you use, what extra patches do you apply to make it actually working? Currently osk driver works fine on 2.6.31. Initially i used to add the omap_mcbsp_request() at the boot time, other wise it hangs up. Audio in current mainline tree works fine for osk5912 with out any such hacks. I believe there are some patches from Russel for the DSP memory mapping during 2.6.29 kernel. --- After all, could someone please give me an advise, what tree, even with buggy omap1510 mcbsp/dsp support, should I base my work on for best results? Omap? Sound? Mainline? I mean not only easy getting the driver working, but also giving it the best possible path into the mainline. You have to use current omap tree with the patches from current sound tree(ASoC omap platform drivers changes) for testing the driver. Somebody correct me if i am wrong.

[PATCH][RFC] OMAP3: PM: Prevent hang in prcm_interrupt_handler
From: Jon Hunter jon-hun...@ti.com
There are two scenarios where a race condition could result in a hang in the
prcm_interrupt handler. These are:
1). Waiting for PRM_IRQSTATUS_MPU register to clear.
Bit 0 of the PRM_IRQSTATUS_MPU register indicates that a wake-up event is
pending for the MPU. This bit can only be cleared if the all the wake-up events
latched in the various PM_WKST_x registers have been cleared. If a wake-up event
occurred during the processing of the prcm interrupt handler, after the
corresponding PM_WKST_x register was checked but before the PRM_IRQSTATUS_MPU
was cleared, then the CPU would be stuck forever waiting for bit 0 in
PRM_IRQSTATUS_MPU to be cleared.
2). Waiting for the PM_WKST_x register to clear.
Some power domains have more than one wake-up source. The PM_WKST_x registers
indicate the source of a wake-up event and need to be cleared after a wake-up
event occurs. When the PM_WKST_x registers are read and before they are cleared,
it is possible that another wake-up event could occur causing another bit to be
set in one of the PM_WKST_x registers. If this did occur after reading a
PM_WKST_x register then the CPU would miss this event and get stuck forever in
a loop waiting for that PM_WKST_x register to clear.
This patch address the above race conditions that would result in a hang.
