Subject: [PATCH 207/423] dwc_otg: Enable the hack for Split Interrupt
|
|
transactions by default
|
|
|
|
dwc_otg.fiq_fsm_mask=0xF has long been a suggestion for users with audio stutters or other USB bandwidth issues.
|
|
So far we are aware of many success stories but no failure caused by this setting.
|
|
Make it a default to learn more.
