* MIPS: BCM63XX: remove bogus ENETSW_TXDMA interrupts from BCM6328Jonas Gorski2012-08-241-4/+4
| | | | | | | | | | These were erroneously copied from BCM6368. BCM6328 does not expose the ENETSW_TXDMA interrupts, and BCM_6328_HIGH_IRQ_BASE + 7 is actually used for the second UART.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So we've had a fair few reports of fbcon handover breakage between efi/vesafb and i915 surface recently, so I dedicated a couple of days to finding the problem. Essentially the last thing we saw was the conflicting framebuffer message and that was all. So after much tracing with direct netconsole writes (printks under console_lock not so useful), I think I found the race. Thread A (driver load) Thread B (timer thread) unbind_con_driver -> | bind_con_driver -> | vc->vc_sw->con_deinit -> | fbcon_deinit -> | console_lock() | | | | fbcon_flashcursor timer fires | console_lock() <- blocked for A | | fbcon_del_cursor_timer -> del_timer_sync (BOOM) Of course because all of this is under the console lock, we never see anything, also since we also just unbound the active console guess what we never see anything. Hopefully this fixes the problem for anyone seeing vesafb->kms driver handoff. v1.1: add comment suggestion from Alan. Cc: stable@vger.kernel.org Signed-off-by: Dave Airlie <airlied@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If you do a page flip with no flags set then event is NULL. If event is NULL then the vmw_gfx driver likes to go digging into NULL and extracts NULL->base.file_priv. On a modern kernel with NULL mapping protection it's just another oops, without it there are some "intriguing" possibilities. What it should do is an open question but that for the driver owners to sort out.

A workaround for him is to again disable semaphores. And indeed, his system has a very hard time to enter rc6 with semaphores enabled. Ben Widawsky run around with a kill-a-watt a lot and noticed: - There are indeed a few rare systems that seem to have a hard time entering rc6 when desktop-idle. - One machine, The Indestructible Toshiba regressed in this behaviour between 3.5 and 3.6 in a merge commit! So rc6 behaviour with the current setting seems to be highly timing dependent and not robust at all. - The behaviour James reported wrt semaphores seems to be a freak timing thing that only happens on his specific machine, confirming that enabling semaphores shouldn't reduce rc6 residency. Now furthermore the Google ChromeOS guys reported [2] a while ago that at least on some machines a simply a blinking cursor can keep the gpu turbo at the highest frequency. This is because the current rps limits used on snb/ivb are highly asymmetric. On the theory that gpu turbo and rc6 tuning values are related, we've tried whether the much saner looking (since much less asymmetric) rps tuning values used for hsw would also help entering rc6 more robustly. And it seems to mostly work, and we don't really have the resources to through-roughly tune things in any better way: The values from the ChromeOS ppl seem to fare a bit worse for James' machine, so I guess we better stick with something vpg (the gpu hw/windows group) provided, hoping that they've done their jobs.

Since vhost_tpgt is 2 bytes and abi_version is 4, the total size would be 230. But gcc needs struct size be aligned to first field size, which is 4 bytes, so it pads the structure by extra 2 bytes to the total of 232. This padding is very undesirable in an ABI: - it can not be initialized easily - it can not be checked easily - it can leak information between kernel and userspace Simplest solution is probably just to make the padding explicit.

Tested with iscsi-target + loopback fabric port LUNs on 3.6-rc0 code. This patch will also need to be picked up for 3.5-stable.
