Instead a getting only one common device "/dev/ion" for all the heaps this patch allow to create one device entry ("/dev/ionX") per heap. Getting an entry per heap could allow to set security rules per heap and global ones for all heaps. Allocation requests will be only allowed if the mask_id match with device minor. Query request could be done on any of the devices.With this patch, sysfs looks like: $ ls /sys/devices/ breakpoint ion platform software system virtual From an Ion perspective, you can have Acked-by: Laura Abbott <redacted> Another Ack for the device model stuff would be good but I'll assume deafening silence means nobody hates it.Greg, can we get your point of view of this ?It's 1 day after the merge window has closed, and my todo patch queue looks like this: $ mdfrm -c ~/mail/todo/ 1523 messages in /home/gregkh/mail/todo/ Please give me a chance to catch up...
commit model ftw, we have 400+ patches for 4.16 already merged and tested and all ready, right when -rc1 gets tagged. Makes the merge window the most relaxed time of all, because all the other maintainers are drowning and wont pester you. Just saying, this is an entirely fixable problem :-P Cheers, Daniel -- Daniel Vetter Software Engineer, Intel Corporation http://blog.ffwll.ch _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
