hello d-kor, When I was testing coyote, I encountered the following problem,
When a missing page prompt appears and the missing page exception is handled, the operating system hangs.
dmesg information is as follows,
fpga_tlb_miss_isr():(irq=107) page fault ISR
fpga_tlb_miss_isr():page fault, vaddr 7ffbc5402000, length 40, cpid 0
tlb_get_user_pages():pid found = 2823
tlb_get_user_pages():allocated 8 bytes for page pointer array for 1 pages @0x000000001bd3b688, passed size 64.
tlb_get_user_pages():pages=0x000000001bd3b688
tlb_get_user_pages():first = 7ffbc5402, last = 7ffbc5402
tlb_get_user_pages():get_user_pages_remote(7ffbc5402000, n_pages = 1, page start = 7a19000000, hugepages = 0)
tlb_get_user_pages():could not get all user pages, -14
fpga_tlb_miss_isr():pages could not be obtained
When I use a large memory page (HUGE_2M), the dmesg information is also similar to the above dmesg information when there is a page missing prompt, and the dmesg information shows hugepages = 0 (and the large memory page is not started)
The text was updated successfully, but these errors were encountered:
Could you try with the latest updates? @d-kor,
Thank you very much for your response,
I have found that the latest version has undergone significant changes compared to previous versions, including overall architecture (configurable), hardware MMU, and software shared memory methods, among others
@d-kor ,
