2012-08-10usb: ehci: tegra: Fix Slab corruption errorPreetham Chandru
Give ownership of the DMA buffer back to the processor first and then free the buffer. Otherwise processor won't be able to access the dma mapped buffers and this would lead to slab corruption. When the DMA buffer is freed without a call to dma_sync_single_for_cpu(), the kernel won't be able to set the buffer as POISON FREE and when we acquire this memory back again the kernel will start printing slab corruption output as the memory is not set to POISON FREE Bug 1017884 Bug 1018161 Reviewed-on: http://git-master/r/#change,122151 Signed-off-by: Preetham Chandru R <pchandru@nvidia.com> Change-Id: I00d6cb185cd2314cccb56f968eb0a05288588c13 Reviewed-on: http://git-master/r/122390 Reviewed-by: Simone Willett <swillett@nvidia.com> Tested-by: Simone Willett <swillett@nvidia.com>

2012-02-08xhci: Fix USB 3.0 device restart on resume.Sarah Sharp
commit d0cd5d482b8a6dc92c6c69a5387baf72ea84f23a upstream. The xHCI hub port code gets passed a zero-based port number by the USB core. It then adds one to in order to find a device slot by port number and device speed by calling xhci_find_slot_id_by_port. That function clearly states it requires a one-based port number. The xHCI port status change event handler was using a zero-based port number that it got from find_faked_portnum_from_hw_portnum, not a one-based port number. This lead to the doorbells never being rung for a device after a resume, or worse, a different device with the same speed having its doorbell rung (which could lead to bad power management in the xHCI host controller). This patch should be backported to kernels as old as 2.6.39.

2012-01-19arm: tegra: usb: Use T30 specific hsic bus resetVinayak Pane
HSIC bus reset apparently needs a WAR. The ehci generic port reset is not enough for modem to connect in stress tests. Instead use pull-down pull-up on Strobe signal of USB HSIC bus. This is AP30 specific workaround.

2012-01-12OHCI: final fix for NVIDIA problems (I hope)Alan Stern
commit c61875977458637226ab093a35d200f2d5789787 upstream. Problems with NVIDIA's OHCI host controllers persist. After looking carefully through the spec, I finally realized that when a controller is reset it then automatically goes into a SUSPEND state in which it is completely quiescent (no DMA and no IRQs) and from which it will not awaken until the system puts it into the OPERATIONAL state. Therefore there's no need to worry about controllers being in the RESET state for extended periods, or remaining in the OPERATIONAL state during system shutdown. The proper action for device initialization is to put the controller into the RESET state (if it's not there already) and then to issue a software reset. Similarly, the proper action for device shutdown is simply to do a software reset. This patch (as1499) implements such an approach. It simplifies initialization and shutdown, and allows the NVIDIA shutdown-quirk code to be removed.

2012-01-12usb: ch9: fix up MaxStreams helperFelipe Balbi
commit 18b7ede5f7ee2092aedcb578d3ac30bd5d4fc23c upstream. [ removed the dwc3 portion of the patch as it didn't apply to older kernels - gregkh] According to USB 3.0 Specification Table 9-22, if bmAttributes [4:0] are set to zero, it means "no streams supported", but the way this helper was defined on Linux, we will *always* have one stream which might cause several problems. For example on DWC3, we would tell the controller endpoint has streams enabled and yet start transfers with Stream ID set to 0, which would goof up the host side. While doing that, convert the macro to an inline function due to the different checks we now need.

2012-01-12xhci: Properly handle COMP_2ND_BW_ERRHans de Goede
commit 71d85724bdd947a3b42a88d08af79f290a1a767b upstream. I encountered a result of COMP_2ND_BW_ERR while improving how the pwc webcam driver handles not having the full usb1 bandwidth available to itself. I created the following test setup, a NEC xhci controller with a single TT USB 2 hub plugged into it, with a usb keyboard and a pwc webcam plugged into the usb2 hub. This caused the following to show up in dmesg when trying to stream from the pwc camera at its highest alt setting: xhci_hcd 0000:01:00.0: ERROR: unexpected command completion code 0x23. usb 6-2.1: Not enough bandwidth for altsetting 9 And usb_set_interface returned -EINVAL, which caused my pwc code to not do the right thing as it expected -ENOSPC. This patch makes the xhci driver properly handle COMP_2ND_BW_ERR and makes usb_set_interface return -ENOSPC as expected. This should be backported to stable kernels as old as 2.6.32.

2012-01-12usb: fix number of mapped SG DMA entriesClemens Ladisch
commit bc677d5b64644c399cd3db6a905453e611f402ab upstream. Add a new field num_mapped_sgs to struct urb so that we have a place to store the number of mapped entries and can also retain the original value of entries in num_sgs. Previously, usb_hcd_map_urb_for_dma() would overwrite this with the number of mapped entries, which would break dma_unmap_sg() because it requires the original number of entries. This fixes warnings like the following when using USB storage devices: ------------[ cut here ]------------ WARNING: at lib/dma-debug.c:902 check_unmap+0x4e4/0x695() ehci_hcd 0000:00:12.2: DMA-API: device driver frees DMA sg list with different entry count [map count=4] [unmap count=1] Modules linked in: ohci_hcd ehci_hcd Pid: 0, comm: kworker/0:1 Not tainted 3.2.0-rc2+ #319 Call Trace: <IRQ> [<ffffffff81036d3b>] warn_slowpath_common+0x80/0x98 [<ffffffff81036de7>] warn_slowpath_fmt+0x41/0x43 [<ffffffff811fa5ae>] check_unmap+0x4e4/0x695 [<ffffffff8105e92c>] ? trace_hardirqs_off+0xd/0xf [<ffffffff8147208b>] ? _raw_spin_unlock_irqrestore+0x33/0x50 [<ffffffff811fa84a>] debug_dma_unmap_sg+0xeb/0x117 [<ffffffff8137b02f>] usb_hcd_unmap_urb_for_dma+0x71/0x188 [<ffffffff8137b166>] unmap_urb_for_dma+0x20/0x22 [<ffffffff8137b1c5>] usb_hcd_giveback_urb+0x5d/0xc0 [<ffffffffa0000d02>] ehci_urb_done+0xf7/0x10c [ehci_hcd] [<ffffffffa0001140>] qh_completions+0x429/0x4bd [ehci_hcd] [<ffffffffa000340a>] ehci_work+0x95/0x9c0 [ehci_hcd] ... ---[ end trace f29ac88a5a48c580 ]--- Mapped at: [<ffffffff811faac4>] debug_dma_map_sg+0x45/0x139 [<ffffffff8137bc0b>] usb_hcd_map_urb_for_dma+0x22e/0x478 [<ffffffff8137c494>] usb_hcd_submit_urb+0x63f/0x6fa [<ffffffff8137d01c>] usb_submit_urb+0x2c7/0x2de [<ffffffff8137dcd4>] usb_sg_wait+0x55/0x161 Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
