Hi, I ran into a strange problem: After I used "bind_evtchn_to_irqhandler" to bind an evtchn to a irq handler, I noticed that the interrupt handler was triggered although actually no IRQ was injected. This problem happened exactly once for each run. Why? Also, I had problem in release shared pages. At the backend, I initially allocate certain pages with alloc_pages(), then map several pages from frontend to the address of the allocated pages. After my work is done, I first unmap the shared pages, then I tried to free the allocated pages with free_pages. But I got a kernel error " page flag bit is not right", and error message also shows that refcount of these pages are 0, which seems to be normal. Did I do something wrong with the page sharing? Thanks a lot! -lily _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
