The VT specific compat_ioctl handlers are the only ones in common code that require the BKL. Moving them into the vt driver lets us remove the BKL from the other handlers and cleans up the code. Signed-off-by: NArnd Bergmann <arnd@arndb.de> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

This is needed and requested in various forms for ConsoleKit, screenblank handling and the like so do the job with a single interface. Also build the interface so that unlike VT_WAITACTIVE and friends it won't miss events. FIXME: Should this be a waitactive ioctl or a new device file you can poll and read events from. We need the code anyway to fix up the existing broken wait for console switch logic but the ConsoleKit people would prefer the new device to the ioctl we have here Signed-off-by: NAlan Cox <alan@linux.intel.com> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

Now we are extracting out methods for shutdown and the like we can add a proper tty_port_close method that knows all the innards of the tty closing process and hides the lot from the caller. At some point in the future this will be paired with a similar open() helper and the drivers can stick to hardware management.

This allows subsytems to provide devtmpfs with non-default permissions for the device node. Instead of the default mode of 0600, null, zero, random, urandom, full, tty, ptmx now have a mode of 0666, which allows non-privileged processes to access standard device nodes in case no other userspace process applies the expected permissions. This also fixes a wrong assignment in pktcdvd and a checkpatch.pl complain. Signed-off-by: NKay Sievers <kay.sievers@vrfy.org> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

This patch converts the existing power tracer into an event tracer, so that power events (C states and frequency changes) can be tracked via "perf". This also removes the perl script that was used to demo the tracer; its functionality is being replaced entirely with timechart.

Draining the BTS buffer on a buffer overflow interrupt takes too long resulting in a kernel lockup when tracing the kernel. Restructure perf_counter sampling into sample creation and sample output. Prepare a single reference sample for BTS sampling and update the from and to address fields when draining the BTS buffer. Drain the entire BTS buffer between a single perf_output_begin() / perf_output_end() pair.

Currently we wake the mmap() consumer once every PAGE_SIZE of data and/or once event wakeup_events when specified. For high speed sampling this results in too many wakeups wrt. the buffer size, hence change this. We move the default wakeup limit to 1/4-th the buffer size, and provide for means to manually specify this limit.
