This was inconsistent with the behavior of other Unix systems. 2) Fix interrupt signal (e.g. ctrl-C) behavior in stopped TTYs With "stty -ixany" (often the default), interrupt signals were ignored in a stopped TTY until the TTY was resumed with the start char (typically ctrl-Q), which was inconsistent with the behavior of other Unix systems.

Linux seems to be the only unix-like OS (recently I've verified this on Solaris, BSD, and Mac OS X) that does *not* behave this way, and I really miss this as a good visual confirmation of the interrupt of a program in the console or xterm. I remember this fondly from many Unixs I've used over the years as well. Bringing this to Linux also seems like a good way to make it yet more compliant with standard unix-like behavior.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The flush code resource handling was having problems where some BIOS reserve the resource in a pnp block and some don't. Also there was a bug in that configure was being called at resume and resetting some of the structs. Signed-off-by: Dave Airlie <airlied@linux.ie>

The semantic match detecting this problem is as follows: // <smpl> @@ expression dev; expression E; @@ * pci_dev_put(dev) ... when != dev = E ( * pci_get_device(...,dev) | * pci_get_device_reverse(...,dev) | * pci_get_subsys(...,dev) | * pci_get_class(...,dev) ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Cc: Dave Jones <davej@codemonkey.org.uk> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Dave Airlie <airlied@linux.ie>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the face of containers and user namespaces, a uid==0 check for security is not safe. Switch to a capability check. I'm not sure I picked the right capability, but this being AGP CAP_SYS_RAWIO seemed to make sense.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a bit of a large hammer but it makes sure the chipset is flushed by writing out 1k of data to an uncached page. We may be able to get better information in the future on how to this better. Signed-off-by: Dave Airlie <airlied@redhat.com>
