Hello: I tried to map the hpet iomem to the virtual memory but i got some error. The log is as following: vtimer | rmgr_pager 4:0 vtimer | hpet_address 0xfed00000 vtimer | hpet size 0x400000 vtimer | hpet_virt_address 0x400000 ROOT: Cannot map page at fed00000 log2_size=12 failed vtimer | IOMem mapping error : No fpage received vtimer | __handle_pf(): L4RM: page fault: no entry in region list vtimer | L4RM: [PF] read at 0x00400000, ip 0100024e, src 8.02 It seems that when I map the iomem the pagesize is not permitted but superpagesize is ok. But i still get the error as "No fpage received". Does anybody tell me what the problem is? Thanks. Cheng Guanghui
