2014-06-02drm/exynos: Fix double locks at PM resumeTakashi Iwai
The recent commit [3ea87855: drm/helper: lock all around force mode restore] introduced drm_modeset_lock_all() in drm_helper_resume_force_mode() itself, while exynos driver takes this lock before calling it. Move the function call outside the lock for avoiding a deadlock. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

Only gma500 is still using this, once that's converted we can kill all this code. If that conversion doesn't happen soonish I think we should just move this helper code into the gma500 driver itself to avoid abuse from new drivers.

2014-06-02drm/exynos: consider deferred probe caseInki Dae
This patch makes sure that exynos drm framework handles deferred probe case correctly. Sub drivers could be probed before resources, clock, regulator, phy or panel, are ready for them so we should make sure that exynos drm core waits until all resources are ready and sub drivers are probed correctly. Chagelog v2: - Make sure that exynos drm core tries to bind sub drivers only in case that they have a pair: crtc and encoder/connector components should be a pair. - Remove unnecessary patch: drm/exynos: mipi-dsi: consider panel driver-deferred probe - Return error type correctly.

2014-06-01bridge: notify user space after fdb updateJon Maxwell
There has been a number incidents recently where customers running KVM have reported that VM hosts on different Hypervisors are unreachable. Based on pcap traces we found that the bridge was broadcasting the ARP request out onto the network. However some NICs have an inbuilt switch which on occasions were broadcasting the VMs ARP request back through the physical NIC on the Hypervisor. This resulted in the bridge changing ports and incorrectly learning that the VMs mac address was external. As a result the ARP reply was directed back onto the external network and VM never updated it's ARP cache. This patch will notify the bridge command, after a fdb has been updated to identify such port toggling.

2014-06-01net: fix wrong mac_len calculation for vlansNikolay Aleksandrov
After 1e785f48d29a ("net: Start with correct mac_len in skb_network_protocol") skb->mac_len is used as a start of the calculation in skb_network_protocol() but that is not always correct. If skb->protocol == 8021Q/AD, usually the vlan header is already inserted in the skb (i.e. vlan reorder hdr == 0). Usually when the packet enters dev_hard_xmit it has mac_len == 0 so we take 2 bytes from the destination mac address (skb->data + VLAN_HLEN) as a type in skb_network_protocol() and return vlan_depth == 4. In the case where TSO is off, then the mac_len is set but it's == 18 (ETH_HLEN + VLAN_HLEN), so skb_network_protocol() returns a type from inside the packet and offset == 22. Also make vlan_depth unsigned as suggested before. As suggested by Eric Dumazet, move the while() loop in the if() so we can avoid additional testing in fast path. Here are few netperf tests + debug printk's to illustrate: cat netperf.tso-on.reorder-on.bugged - Vlan -> device (reorder on, default, this case is okay) MIGRATED TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 192.168.3.1 () port 0 AF_INET Recv Send Send Socket Socket Message Elapsed Size Size Size Time Throughput bytes bytes bytes secs. 10^6bits/sec 87380 16384 16384 10.00 7111.54 [ 81.605435] skb->len 65226 skb->gso_size 1448 skb->proto 0x800 skb->mac_len 0 vlan_depth 0 type 0x800 - Vlan -> device (reorder off, bad) cat netperf.tso-on.reorder-off.bugged MIGRATED TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 192.168.3.1 () port 0 AF_INET Recv Send Send Socket Socket Message Elapsed Size Size Size Time Throughput bytes bytes bytes secs. 10^6bits/sec 87380 16384 16384 10.00 241.35 [ 204.578332] skb->len 1518 skb->gso_size 0 skb->proto 0x8100 skb->mac_len 0 vlan_depth 4 type 0x5301 0x5301 are the last two bytes of the destination mac. And if we stop TSO, we may get even the following: [ 83.343156] skb->len 2966 skb->gso_size 1448 skb->proto 0x8100 skb->mac_len 18 vlan_depth 22 type 0xb84 Because mac_len already accounts for VLAN_HLEN.

So add the proper dependency in Kconfig so that the above can't happen. I moved DRM_PTN3460 earlier in Kconfig, next to the I2C helper module section, so that the user has a chance to select it before moving to the Exynos-specific section. IMHO the proper way to solve the problem would be to turn ptn3460 into a clean I2C driver, similar to the other I2C helper chip drivers. It's the only way to not sink into impossible-to-guess dependencies. Then ptn3460 could even be moved together with the other I2C helper chip drivers.

2014-06-02drm/exynos: use 4WORD dma burst length for small fbsRahul Sharma
In case of exynos, setting dma-burst to 16Word causes permanent tearing for very small buffers, e.g. cursor buffer. Burst Mode switching, which is based on overlay size is not recommended as overlay size varies a lot towards the end of the screen. This causes unstable DMA which results into tearing again. Rendering small buffers with lower burst size doesn't cause any noticable performance overhead. 128 pixel width is selected based on mulitple experiments with exynos5 SoCs.
