Problems with 3.4-rc5

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

I've just given 3.4-rc5 a quick run-through on my GUMSTIX Overo (AM3703), and have noticed a couple of issues...

Firstly, it fails to build "drivers/mfd/omap-usb-host.c" if you have:

CONFIG_USB_EHCI_HCD=m
CONFIG_USB_EHCI_ROOT_HUB_TT=y
CONFIG_USB_EHCI_TT_NEWSCHED=y
CONFIG_USB_EHCI_HCD_OMAP=y

drivers/mfd/omap-usb-host.c: In function 'omap_usbhs_init':
drivers/mfd/omap-usb-host.c:524:3: error: implicit declaration of function 'cpu_is_omap3430'
drivers/mfd/omap-usb-host.c:524:3: error: implicit declaration of function 'omap_rev'
drivers/mfd/omap-usb-host.c:524:43: error: 'OMAP3430_REV_ES2_1' undeclared (first use in this function)
drivers/mfd/omap-usb-host.c:524:43: note: each undeclared identifier is reported only once for each function it appears in

I'm assuming this has been spotted and I've missed the fix (just a missing include?).

Secondly, I get the following when booted:
...
[    4.701232] devtmpfs: mounted
[    4.704772] Freeing init memory: 168K
[    4.827301] omapdss DISPC error: FIFO UNDERFLOW on gfx, disabling the overlay
...

Which means that the display doesn't work.

I am currently running 3.3, which works just fine and doesn't give an underflow.

So was wondering what changes have been made that may affect this? There were problems in the 3.2-era due to runtime-
PM causing a similar issue, has anything changed around here again?

(as a side not: the panel I use is a custom 800x480 added to panel-generic-dpi.c, with board-overo.c updated to use it).

Cheers,
Joe Woodward
