Does this description looks good ? /** * vm_insert_range - insert range of kernel pages into user vma * @vma: user vma to map to * @addr: target user address of this page * @pages: pointer to array of source kernel pages * @page_count: number of pages need to insert into user vma * * This allows drivers to insert range of kernel pages they've allocated * into a user vma. This is a generic function which drivers can use * rather than using their own way of mapping range of kernel pages into * user vma. * * Context - Process context. Called by mmap handlers. * Return - int error value * 0 - OK * -EINVAL - Invalid argument * -ENOMEM - No memory * -EFAULT - Bad address * -EBUSY - Device or resource busy */ _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
