2011-04-13USB: musb: blackfin: work around anomaly 05000450Mike Frysinger3-0/+37
DMA mode 1 data corruption anomaly on Blackfin systems. This issue is specific to the Blackfin silicon as the bug appears to be related to the connection of the musb ip to the bus/dma fabric. Data corruption when using USB DMA mode 1. (Issue manager 17-01-0105) DMA mode 1 allows large size transfers to generate a single interrupt at the end of the entire transfer. The transfer is split up in packets of length specified in the Maximum Packet Size field for that endpoint. If the transfer size is not an integer multiple of the Maximum Packet Size, a short packet will be present at the end of the transfer. Under certain conditions this packet may be corrupted in the USB FIFO. Workaround: Use DMA mode 1 to transfer (n* Maximum Packet Size) and schedule DMA mode 0 to transfer the short packet. As an example if your transfer size is 33168 bytes and Maximum Packet Size equals 512, schedule [33168 - (33168 mod 512)] in DMA mode 1 and the remainder (33168 mod 512) in DMA mode 0.

2011-04-13usb: musb: temporarily make it boolFelipe Balbi1-3/+3
Due to the recent changes to musb's glue layers, we can't compile musb-hdrc as a module - compilation will break due to undefined symbol musb_debug. In order to fix that, we need a big re-work of the debug support on the MUSB driver. Because that would mean a lot of new code coming into the -rc series, it's best to defer that to next merge window and for now just disable module support for MUSB. Once we get the refactor of the debugging support done, we can simply revert this patch and things will go back to normal again.

2011-04-12ath9k_hw: fix stopping rx DMA during resetsFelix Fietkau4-16/+26
During PHY errors, the MAC can sometimes fail to enter an idle state on older hardware (before AR9380) after an rx stop has been requested. This typically shows up in the kernel log with messages like these: ath: Could not stop RX, we could be confusing the DMA engine when we start RX up ------------[ cut here ]------------ WARNING: at drivers/net/wireless/ath/ath9k/recv.c:504 ath_stoprecv+0xcc/0xf0 [ath9k]() Call Trace: [<8023f0e8>] dump_stack+0x8/0x34 [<80075050>] warn_slowpath_common+0x78/0xa4 [<80075094>] warn_slowpath_null+0x18/0x24 [<80d66d60>] ath_stoprecv+0xcc/0xf0 [ath9k] [<80d642cc>] ath_set_channel+0xbc/0x270 [ath9k] [<80d65254>] ath_radio_disable+0x4a4/0x7fc [ath9k] When this happens, the state that the MAC enters is easy to identify and does not result in bogus DMA traffic, however to ensure a working state after a channel change, the hardware should still be reset.

2011-04-12drm/i915: Sanitize the output registers after resumeChris Wilson1-32/+36
Similar to booting, we need to inspect the state left by the BIOS and remove any conflicting bits before we take over. The example reported by Seth Forshee is very similar to the bug we encountered with the state left by grub2, that the crtc pipe<->planning mapping was reversed from our expectations and so we failed to turn off the outputs when booting or, in this case, resuming. This may be in fact the same bug, but triggered at resume time. This patch rearranges the code we already have to clear up the conflicting state upon init and calls it from reset (which is called after we have lost control of the hardware, i.e. along both the boot and resume paths) instead.

2011-04-12drm/i915/tv: Fix modeset flickering introduced in 7f58aabc3Sitsofe Wheeler1-2/+2
The tidy ups in 7f58aabc369014fda3a4a33604ba0a1b63b941ac ("drm/i915: cleanup per-pipe reg usage") changed intel_crtc->plane to intel_crtc->pipe in intel_tv_mode_set(). This caused the screen to quickly turn off before returning whenever modesetting/mode probing took place on my 915GM EeePC 900 creating a flickering effect. This patch changes intel_crtc->pipe back to intel_crtc->plane which solves the problem for me.

2011-04-12drm/i915/tv: Only poll for TV connectionsMathew McKernan1-2/+1
As a probe for a TV connection modifies the TV_CTL register, it causes a loss of sync and a regular glitch on the output. This is highly undesirable when using the TV, so only poll for TV connections and wait for an explicit query for detecting the disconnection event.

2011-04-12drm/i915/tv: Remember the detected TV typeMathew McKernan1-0/+2
During detect() we would probe the connection bits to determine if there was a TV attached, and what video input type (Component, S-Video, Composite, etc) to use. However, we promptly discarded this vital bit of information and never propagated it to where it was used to determine the correct modes and setup the control registers. Fix it! This fixes a regression from 7b334fcb45b757ffb093696ca3de1b0c8b4a33f1.

2011-04-12sfc: Do not use efx_process_channel_now() in online self-testBen Hutchings5-29/+23
During self-tests we use efx_process_channel_now() to handle completion and other events synchronously. This disables interrupts and NAPI processing for the channel in question, but it may still be interrupted by another channel. A single socket may receive packets from multiple net devices or even multiple channels of the same net device, so this can result in deadlock on a socket lock. Receiving packets in process context will also result in incorrect classification by the network cgroup classifier. Therefore, we must only use efx_process_channel_now() in the offline loopback tests (which never deliver packets up the stack) and not for the online interrupt and event tests. For the interrupt test, there is no reason to process events. We only care that an interrupt is raised. For the event test, we want to know whether events have been received, and there may be many events ahead of the one we inject. Therefore remove efx_channel::magic_count and instead test whether efx_channel::eventq_read_ptr advances. This is currently an event queue index and might wrap around to exactly the same value, resulting in a false negative. Therefore move the masking to efx_event() and efx_nic_eventq_read_ack() so that it cannot wrap within the time of the test. The event test also tries to diagnose failures by checking whether an event was delivered without causing an interrupt. Add and use a helper function that only does this.

2011-04-12thinkpad-acpi fails to load with newer Thinkpad X201s BIOSKeith Packard1-2/+1
The new BIOS has a slightly different EC version string. From a1541710300b083a1a9acff2890d721d15ede62b Mon Sep 17 00:00:00 2001 From: Keith Packard <[email protected]> Date: Sun, 13 Mar 2011 23:46:22 -0700 Subject: [PATCH] thinkpad-acpi: Some BIOS versions don't end in WW, remove check My X201s BIOS version string is 6QET46V1 (1.16 ). The EC version string is 6QHT28WW-1.09. The driver was requiring that both of these have 'WW' in positions 6 and 7. I don't know what the significance of having 'V1' there instead is, but removing the test makes the driver load on my machine.

2011-04-12sfc: Stop the TX queues during loopback self-testsNeil Turton3-2/+5
If the TX queues are running during loopback self tests, host traffic gets looped back which causes the test to fail. Avoid restarting the TX queues after the port reset so that any packets sent by the host get held back until after the tests have completed. [bwh: Also wake all TX queues at the end of self-tests.] Signed-off-by: Ben Hutchings <[email protected]>
