* drm/i915: Hook connector to encoder during load detection (fixes tv/vga detect)Keith Packard2009-06-09
| | | | | | | | | With the DRM-driven DPMS code, encoders are considered idle unless a connector is hooked to them, so mode setting is skipped. This makes load detection fail as none of the hardware is enabled. Signed-off-by: Keith Packard <keithp@keithp.com> Signed-off-by: Eric Anholt <eric@anholt.net>

* drm/i915: Sanity check execbuffer arguments before touching state.Chris Wilson2009-06-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By sending a broken execbuffer (its length was not suitably aligned) I triggered an operation upon a freed object. The invalid alignment was discovered after updating the write_domain on the object but before the object was placed on the active queue. So during the unwind process following the error, the now freed object attempts to flush its non-existent, but outstanding, GPU writes causing this use-after-free.

* drm/i915: Change GEM throttling to be 20ms like the comment says.Eric Anholt2009-06-04
| | | | | | | | | | | | | | | | | | | keithp didn't like the original 20ms plan because a cooperative client could be starved by an uncooperative client. There may even have been problems with cooperative clients versus cooperative clients. So keithp changed throttle to just wait for the second to last seqno emitted by that client. It worked well, until we started getting more round-trips to the server due to DRI2 -- the server throttles in BlockHandler, and so if you did more than one round trip after finishing your frame, you'd end up unintentionally syncing to the swap. Fix this by keeping track of the client's requests, so the client can wait when it has an outstanding request over 20ms old. This should have non-starving behavior, good behavior in the presence of restarts, and less waiting. Improves high-settings openarena performance on my GM45 by 50%.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch to fix bad length checking in e1000. E1000 by default does two things: 1) Spans rx descriptors for packets that don't fit into 1 skb on recieve 2) Strips the crc from a frame by subtracting 4 bytes from the length prior to doing an skb_put Since the e1000 driver isn't written to support receiving packets that span multiple rx buffers, it checks the End of Packet bit of every frame, and discards it if its not set. This places us in a situation where, if we have a spanning packet, the first part is discarded, but the second part is not (since it is the end of packet, and it passes the EOP bit test). If the second part of the frame is small (4 bytes or less), we subtract 4 from it to remove its crc, underflow the length, and wind up in skb_over_panic, when we try to skb_put a huge number of bytes into the skb. This amounts to a remote DOS attack through careful selection of frame size in relation to interface MTU. The fix for this is already in the e1000e driver, as well as the e1000 sourceforge driver, but no one ever pushed it to e1000. This is lifted straight from e1000e, and prevents small frames from causing the underflow described above Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Tested-by: Andy Gospodarek <andy@greyhouse.net> Signed-off-by: David S.

The phy power state persists across reboots; Windows, some BIOSes, and older versions of Linux don't bother to power up the phy again, forcing users to remove all power to get the interface working (see http://bugzilla.kernel.org/show_bug.cgi?id=13072). Leaving the phy powered on is the safest default behavior. Users accustomed to seeing the link state reflect the interface state and/or wanting to minimize power consumption can set phy_power_down=1 if compatibility with other OSes is not an issue.

Rx descriptors are fed with the a page buffer bus address + page chunk offset. The page buffer bus address is set and retrieved through pci_unamp_addr_set(), pci_unmap_addr(). These functions being meaningless on x86 (if CONFIG_DMA_API_DEBUG is not set). The HW ends up with a bogus bus address. This patch saves the page buffer bus address for all plaftorms.

| * | atlx: move modinfo data from atlx.h to atl1.cAlex Chiang2009-05-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Both atl1.c and atl2.c include atlx.h, which defines some modinfo stuff. But atl2.c seems like it doesn't want the modinfo data from atlx.h, as it defines its own. Running modinfo on atl2.ko, we get conflicting information: $ /sbin/modinfo drivers/net/atlx/atl2.ko | egrep "version|description|author" version: 2.2.3 description: Atheros Fast Ethernet Network Driver author: Atheros Corporation <xiong.huang@atheros.com>, Chris Snook <csnook@redhat.com> version: 2.1.3 author: Xiong Huang <xiong.huang@atheros.com>, Chris Snook <csnook@redhat.com>, Jay Cliburn <jcliburn@gmail.com> Move the modinfo data out of atlx.h and into atl1.c to eliminate the confusion: $ /sbin/modinfo drivers/net/atlx/atl1.ko | egrep "version|description|author" version: 2.1.3 author: Xiong Huang <xiong.huang@atheros.com>, Chris Snook <csnook@redhat.com>, Jay Cliburn <jcliburn@gmail.com> description: Atheros L1 Gigabit Ethernet Driver $ /sbin/modinfo drivers/net/atlx/atl2.ko | egrep "version|description|author" version: 2.2.3 description: Atheros Fast Ethernet Network Driver author: Atheros Corporation <xiong.huang@atheros.com>, Chris Snook <csnook@redhat.com> Reported-by: Scott Scriven <scott.scriven@hp.com> Signed-off-by: Alex Chiang <achiang@hp.com> Acked-by: Jay Cliburn <jcliburn@gmail.com> Signed-off-by: David S.
