Currently I'm only able to rmmod -f omapdrm, not sure if these issues might be related.
Hmm, I always use modules, and can unload omapdrm and drm fine. But there's a sequence that must be followed. However, the sequence starts with unloading omapdrm... What behavior you see with rmmod?
Hmm maybe it's output specific somehow?
I just tried again with the following with v5.7. I see the omapdrm usage count issue happen at least on duovero, but don't seem to currently get /dev/fb0 initialized on x15 with these:
modprobe omapdrm #modprobe connector_hdmi # up to v5.6 modprobe display-connector # starting with v5.7-rc1 modprobe ti-tpd12s015 # beagle-x15 modprobe omapdss
# rmmod omapdrm rmmod: ERROR: Module omapdrm is in use
# lsmod | grep omapdrm omapdrm 65536 1 omapdss_base 16384 2 omapdrm,omapdss drm_kms_helper 155648 3 omapdss_base,omapdrm,omapdss drm 372736 7 ti_tpd12s015,omapdss_base,display_connector,omapdrm,omapdss,drm_kms_helper
I'm also seeing the rmmod omapdrm issue on am437x-sk-evm:
modprobe pwm-omap-dmtimer modprobe pwm-tiecap modprobe pwm_bl modprobe omapdrm modprobe panel-simple modprobe display-connector # starting with v5.7-rc1 modprobe omapdss
# rmmod omapdrm rmmod: ERROR: Module omapdrm is in use
On beagle-x15 I see these errors after modprobe:
DSS: OMAP DSS rev 6.1 omapdss_dss 58000000.dss: bound 58001000.dispc (ops dispc_component_ops [omapdss]) omapdss_dss 58000000.dss: bound 58040000.encoder (ops hdmi5_component_ops [omapdss]) [drm] Supports vblank timestamp caching Rev 2 (21.10.2013). omapdrm omapdrm.0: [drm] Cannot find any crtc or sizes [drm] Initialized omapdrm 1.0.0 20110917 for omapdrm.0 on minor 0 omapdrm omapdrm.0: [drm] Cannot find any crtc or sizes aic_dvdd_fixed: disabling ldousb: disabling
Maybe I'm missing some related module on x15?
Still did not figure what I might be missing on x15 :)
