narada,
Make sure that priority levels meet the requirements (app_code and app_ss selectors should have RPL==3, i.e. app_code = app_code_l+3 or something like that). |

No... with RPL all fine...
May be this is not an answer, but when I initialized TR register (added tss_selector and LTR ... ... ) all start working propertly... it's very interesting... as I understood, IRETD instruction or another (instead of Jxx) needed a TSS... (Times ago all worked fine, but I decided to do scheduler withous TSS, as software task swith... and now I am using sowtware t.sw., but TSS structure just must be in system... as think...) |
