2016-07-14drm/nouveau/disp/g94: implement workaround for dvi issue on fx380Ben Skeggs
Fixes the second DVI output on Quadro FX380. Thanks to NVIDIA for providing the details on the full workaround. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-07-14drm/nouveau/bios: pointers beyond end of first image need special handlingBen Skeggs
Makes common the code that was previously used by the PMU table parsing, as it appears other tables need this too. Not much of an idea what this is all about... Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2016-07-14drm/nouveau/disp/nv50-: fix lookup of udisp table under certain circumstancesBen Skeggs
Some VBIOS have separate tables for each link of a given output path, which means we have to specify the specific link we're using instead of all possible links. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2016-07-14drm/nouveau/clk/gf100-: Clean up PLL locking testRoy Spliet
Corresponds with GT215. Don't rely on the lock test logic being unconditionally enabled, and disable test logic when done (presumably to save power). v2: Remove warning, nvkm_msec already warns on time-out Signed-off-by: Roy Spliet <nouveau@spliet.org> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-07-14drm/nouveau/secboot: lazy-load firmware and be more resilientAlexandre Courbot
Defer the loading of firmware files to the chip-specific part of secure boot. This allows implementations to retry loading firmware if the first attempt failed ; for the GM200 implementation, this happens when trying to reset a falcon, typically in reaction to GR init. Firmware loading may fail for a variety of reasons, such as the filesystem where they reside not being ready at init time. This new behavior allows GR to be initialized the next time we try to use it if the firmware has become available.

2016-07-14drm/nouveau/secboot/gm200: make firmware loading re-callableAlexandre Courbot
Make it possible to call gm20x_secboot_prepare_blobs() several times after either success or failure without re-building already existing blobs. The function will now try to load firmware files that have previously failed before returning success.

2016-07-14drm/nouveau/gr/gf100: handle secure boot errorsAlexandre Courbot
Handle and propagate secure boot errors. Failure to do so results in Nouveau incorrectly believing init has succeeded and a completely black display during boot. If we propagate the error, GR init will fail and the user will at least have a working display. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2016-07-14drm/nouveau/volt: save the voltage range we are able to setKarol Herbst
We shouldn't set voltages below the min or above the max voltage the gpu is able to set, so save the range for future lookups.

2016-07-14drm/nouveau/clk/gm20b: add glitchless and DFS supportAlexandre Courbot
This patch adds support for advanced features supported by the Noise-Aware PLL of Maxwell. Glitchless switch allows the PL field to be updated without disabling the PLL first if the SYNC_MODE bit of the CFG register is set. More significantly, DFS allows the PLL to monitor the actual input voltage and to dynamically lower the output frequency accordingly. This allows the clock to be more tolerant of lower voltages. These improvements are only supported for Tegra speedos >= 1. Also add the voltage table that is suitable for GM20B's NAPLL. This change needs to be done atomically for the right voltages to be used by the clock driver. v2.

2016-07-14drm/nouveau/clk/gk20a: improve MNP programmingAlexandre Courbot
Split the MNP programming function into two functions for the cases where we allow sliding or not, instead of making it take a parameter for this. This results in less conditionals in the code and makes it easier to read. Also make the MNP programming functions take the PLL parameters as arguments, and move bits of code to more relevant places (previous programming tended to be just-in-time, which added more conditionnals in the code).

2016-07-14drm/nouveau/clk/gk20a: parameterize PLL settingsAlexandre Courbot
Make functions manipulating PLL settings take them as an argument, instead of assuming we want to work on the copy in the gk20a_clk structure. This makes these functions more flexible, which we will need in GM20B. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2016-07-13Merge branch 'sk_filter-trim-limit'David S. Miller
Willem de Bruijn says: ==================== limit sk_filter trim to payload Sockets can apply a filter to incoming packets to drop or trim them. Fix two codepaths that call skb_pull/__skb_pull after sk_filter without checking for packet length. Reading beyond skb->tail after trimming happens in more codepaths, but safety of reading in the linear segment is based on minimum allocation size (MAX_HEADER, GRO_MAX_HEAD, ..). ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2016-07-13dccp: limit sk_filter trim to payloadWillem de Bruijn
Dccp verifies packet integrity, including length, at initial rcv in dccp_invalid_packet, later pulls headers in dccp_enqueue_skb. A call to sk_filter in-between can cause __skb_pull to wrap skb->len. skb_copy_datagram_msg interprets this as a negative value, so (correctly) fails with EFAULT. The negative length is reported in ioctl SIOCINQ or possibly in a DCCP_WARN in dccp_close. Introduce an sk_receive_skb variant that caps how small a filter program can trim packets, and call this in dccp with the header length. Excessively trimmed packets are now processed normally and queued for reception as 0B payloads.

2016-07-13rose: limit sk_filter trim to payloadWillem de Bruijn
Sockets can have a filter program attached that drops or trims incoming packets based on the filter program return value. Rose requires data packets to have at least ROSE_MIN_LEN bytes. It verifies this on arrival in rose_route_frame and unconditionally pulls the bytes in rose_recvmsg. The filter can trim packets to below this value in-between, causing pull to fail, leaving the partial header at the time of skb_copy_datagram_msg. Place a lower bound on the size to which sk_filter may trim packets by introducing sk_filter_trim_cap and call this for rose packets.

Start all tx queues (including inactive ones) when opening the netdev. Stop all tx queues (including inactive ones) when closing the netdev. This is a workaround for the tx timeout watchdog false alarm issue in which the netdev watchdog is polling all the tx queues which may include inactive queues and thus once lowering the real tx queues number (ethtool -L) it will generate tx timeout watchdog false alarms.
