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
...
Could you add some dss debug prints? You can add "omapdss.debug=1 debug"
in the bootargs to get that.
There was a feature called fifo merge added in 3.4, this might lead to
underflow, we had tested this using a DVI monitor on beagle but didn't
see any underflows.
Are you trying this out on 3.4 for the first time? What was the last
kernel revision on which you tested this and didn't see any issues?
Thanks,
Archit
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
