* | video: adf: add buffer padding quirkGreg Hackmann2016-02-16
| | | | | | | | | | | | | | | | | | | | | | | | | | Quirks specify common behaviors that vary slightly among devices, and which ADF must account for. The buffer padding quirk captures the way different devices fetch the last scanline in a buffer: some devices fetch an entire line (including padding to the pitch) while others only fetch up to the visible width. ADF's buffer size validation now takes this quirk into account. Change-Id: I828b13316e27621d8a9efd9d5fffa6ce12a525ff Signed-off-by: Greg Hackmann <ghackmann@google.com>
* | video: adf: ensure consistent alignment on userspace facing structsGreg Hackmann2016-02-16
| | | | | | | | | | | | | | | | | | | | | | 64-bit types in structs create alignment problems when a 32-bit x86 userspace talks to an x86_64 kernel. In most cases the 64-bit types can be replaced with 32-bit ones, since they're being used for fds and should have been __s32 in the first place. For adf_vsync_event, alignment can be enforced by making the timestamp an __aligned_u64. Change-Id: I87cf73d8f57730bd7bb43ffce6b7b411eb0ff198 Signed-off-by: Greg Hackmann <ghackmann@google.com>
* | video: adf: replace fbdev helper's open flag with refcountGreg Hackmann2016-02-16
| | | | | | | | | | | | | | | | | | | | | | | | | | A device's fb_info is shared between clients. fb_release() is called when each client is released, not just the last one. Since the fbdev helper needs to release its dma-buf when the last client goes away, it must keep its own reference count. fbmem and fbcon hold different locks while calling fb_release(), so explicit locking is needed.

* | cpufreq: interactive: New 'interactive' governorMike Chan2016-02-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This governor is designed for latency-sensitive workloads, such as interactive user interfaces. The interactive governor aims to be significantly more responsive to ramp CPU quickly up when CPU-intensive activity begins. Existing governors sample CPU load at a particular rate, typically every X ms. This can lead to under-powering UI threads for the period of time during which the user begins interacting with a previously-idle system until the next sample period happens. The 'interactive' governor uses a different approach. Instead of sampling the CPU at a specified rate, the governor will check whether to scale the CPU frequency up soon after coming out of idle. When the CPU comes out of idle, a timer is configured to fire within 1-2 ticks. If the CPU is very busy from exiting idle to when the timer fires then we assume the CPU is underpowered and ramp to MAX speed. If the CPU was not sufficiently busy to immediately ramp to MAX speed, then the governor evaluates the CPU load since the last speed adjustment, choosing the highest value between that longer-term load or the short-term load since idle exit to determine the CPU speed to ramp to. A realtime thread is used for scaling up, giving the remaining tasks the CPU performance benefit, unlike existing governors which are more likely to schedule rampup work to occur after your performance starved tasks have completed. The tuneables for this governor are: /sys/devices/system/cpu/cpufreq/interactive/min_sample_time: The minimum amount of time to spend at the current frequency before ramping down. This is to ensure that the governor has seen enough historic CPU load data to determine the appropriate workload. Default is 80000 uS. /sys/devices/system/cpu/cpufreq/interactive/go_maxspeed_load The CPU load at which to ramp to max speed. Default is 85.

* | net: ipv6: autoconf routes into per-device tablesLorenzo Colitti2016-02-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, IPv6 router discovery always puts routes into RT6_TABLE_MAIN. This causes problems for connection managers that want to support multiple simultaneous network connections and want control over which one is used by default (e.g., wifi and wired). To work around this connection managers typically take the routes they prefer and copy them to static routes with low metrics in the main table. This puts the burden on the connection manager to watch netlink to see if the routes have changed, delete the routes when their lifetime expires, etc. Instead, this patch adds a per-interface sysctl to have the kernel put autoconf routes into different tables. This allows each interface to have its own autoconf table, and choosing the default interface (or using different interfaces at the same time for different types of traffic) can be done using appropriate ip rules. The sysctl behaves as follows: - = 0: default. Put routes into RT6_TABLE_MAIN as before. - > 0: manual. Put routes into the specified table. - < 0: automatic. Add the absolute value of the sysctl to the device's ifindex, and use that table. The automatic mode is most useful in conjunction with net.ipv6.conf.default.accept_ra_rt_table. A connection manager or distribution could set it to, say, -100 on boot, and thereafter just use IP rules.

* | netfilter: adding the original quota2 from xtables-addonsJP Abgrall2016-02-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The original xt_quota in the kernel is plain broken: - counts quota at a per CPU level (was written back when ubiquitous SMP was just a dream) - provides no way to count across IPV4/IPV6. This patch is the original unaltered code from: http://sourceforge.net/projects/xtables-addons at commit e84391ce665cef046967f796dd91026851d6bbf3 Change-Id: I19d49858840effee9ecf6cff03c23b45a97efdeb Signed-off-by: JP Abgrall <jpa@google.com>
* | netfilter: add xt_qtaguid matching moduleJP Abgrall2016-02-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This module allows tracking stats at the socket level for given UIDs. It replaces xt_owner. If the --uid-owner is not specified, it will just count stats based on who the skb belongs to. This will even happen on incoming skbs as it looks into the skb via xt_socket magic to see who owns it. If an skb is lost, it will be assigned to uid=0. To control what sockets of what UIDs are tagged by what, one uses: echo t $sock_fd $accounting_tag $the_billed_uid \ > /proc/net/xt_qtaguid/ctrl So whenever an skb belongs to a sock_fd, it will be accounted against $the_billed_uid and matching stats will show up under the uid with the given $accounting_tag. Because the number of allocations for the stats structs is not that big: ~500 apps * 32 per app we'll just do it atomic. This avoids walking lists many times, and the fancy worker thread handling. Slabs will grow when needed later. It use netdevice and inetaddr notifications instead of hooks in the core dev code to track when a device comes and goes. This removes the need for exposed iface_stat.h. Put procfs dirs in /proc/net/xt_qtaguid/ ctrl stats iface_stat/<iface>/... The uid stats are obtainable in ./stats.

* | Hack: net: PPPoPNS and PPPoLAC build fixes for 4.1Amit Pundir2016-02-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Upstream commit c0371da6047a "put iov_iter into msghdr", added iov_iter and removed direct access to scatter/gather array elements in msghdr. It broke PPPoLAC and PPPoPNS. Lets restore the direct access to scatter/gather array in msghdr for the time being. Otherwise we run into following build failure: ---------- drivers/net/ppp/pppolac.c: In function ‘pppolac_xmit_core’: drivers/net/ppp/pppolac.c:210:4: error: unknown field ‘msg_iov’ specified in initializer .msg_iov = (struct iovec *)&iov, ^ drivers/net/ppp/pppolac.c:211:4: error: unknown field ‘msg_iovlen’ specified in initializer .msg_iovlen = 1, ^ make[3]: *** [drivers/net/ppp/pppolac.o] Error 1 ---------- Change-Id: I2a1245a156da6d93b49f5cfd10506381b0eff005 Signed-off-by: Amit Pundir <amit.pundir@linaro.org> Signed-off-by: Dmitry Shmidt <dimitrysh@google.com>
