For reference, I updated my code to dump out the HID0, HID1, HID4, and HDI5 values for the ap's, dumping values from both before FreeBSD changes them and after they are changed. I was curious. The result was: HIOR(311) before: fff00000, 0 after before: HID0 fc1c000000000000 after: HID0 0151108100000000 before: HDI1 0 after: HDI1 fd3c200000000000 before: HID4 10000000000, HID5 0 after: HID4 1000000000, HID5 0 So differences in: (Hopefully I matched everything up correctly) HID0: one_ppc, do_single, isync_sc, ser-gp, reserved bits 4:5, deep nap, doze, nhr, ext_tb_en, reserved bit 24, en_attn. HID1: bht_pm, en_ls, en_cc, en_ic, pf_mode, en_if_cach, en_ic_rec, ic_pe. HID4: rm_ci, en_sp_dtw. HID5: none. I'll note that en_ic is described with: QUOTE Enable instruction cache (must be =E2=80=981=E2=80=99 for proper functionin= g). END QUOTE (Not that there is a description of what the improper functioning of the 970MP would be.) This was the wording I was most worried about. [There are some other bits that have differences from "preferred state", not that I know the importance of them.] [slbtrap and handle_kernel_slb_spill are using mftb() and so ext_tb_en being different is in use before HID0 is updated.] --=20 You are receiving this mail because: You are the assignee for the bug.=
