Hi Moritz: Hao and I did several rounds of review and fix in the mailing list. Now the patches are all acked by Hao.
Could you please help review it when you have time? Thanks! :) On Mon, Apr 20, 2020 at 04:11:36PM +0800, Xu Yilun wrote: > This patchset add interrupt support to FPGA DFL drivers. > > With these patches, DFL driver will parse and assign interrupt resources > for enumerated feature devices and their sub features. > > This patchset also introduces a set of APIs for user to monitor DFL > interrupts.
