A while ago I provided a patch that fixed device detection after device removal (USB: sl811-hcd: Fix device disconnect). Chris Brissette pointed out that the detection/removal counter method to distinguish insert or remove my fail under certain conditions. Latest SL811HS datasheet (Document 38-08008 Rev. *D) indicates that bit 6 (SL11H_INTMASK_RD) of the Interrupt Status Register together with bit 5 (SL11H_INTMASK_INSRMV) can be used to determine whether a device has been inserted or removed.

A hanging has been detected in ohci-at91 while going in suspend to ram. This is due to asynchronous operations between ohci reset and ohci clocks shutdown. This patch adds the reading of the control register between the reset of the ohci and clocks stop. This "flush the writes" idea was taken from ohci-hcd.c file (ohci_shutdown() function).

In an error handling case the lock is not unlocked. The return is converted to a goto, to share the unlock at the end of the function. A simplified version of the semantic patch that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r exists@ expression E1; identifier f; @@ f (...) { <+... * spin_lock_irqsave (E1,...); ... when != E1 * return ...; ...+> } // </smpl> Signed-off-by:

With patch as1329 (USB: convert to the runtime PM framework), we make USB_SUSPEND depend on PM_RUNTIME instead of CONFIG_PM. Also, CONFIG_USB_OTG selects CONFIG_USB_SUSPEND. If PM_RUNTIME is not enabled, and we try to enable USB_OTG, we will end up with CONFIG_USB_SUSPEND selected. This is due to a known bug with the select statement. This makes the build break on various OMAP configs (which have CONFIG_USB_OTG set by default, but do not yet have CONFIG_PM_RUNTIME enabled). Avoid this by changing the logic for CONFIG_USB_OTG from "select USB_SUSPEND" to "depends on USB_SUSPEND" Signed-off-by:

For periodic endpoints, we must let the xHCI hardware know the maximum payload an endpoint can transfer in one service interval. The xHCI specification refers to this as the Maximum Endpoint Service Interval Time Payload (Max ESIT Payload). This is used by the hardware for bandwidth management and scheduling of packets. For SuperSpeed endpoints, the maximum is calculated by multiplying the max packet size by the number of bursts and the number of opportunities to transfer within a service interval (the Mult field of the SuperSpeed Endpoint companion descriptor). Devices advertise this in the wBytesPerInterval field of their SuperSpeed Endpoint Companion Descriptor. For high speed devices, this is taken by multiplying the max packet size by the "number of additional transaction opportunities per microframe" (the high bits of the wMaxPacketSize field in the endpoint descriptor). For FS/LS devices, this is just the max packet size. The other thing we must set in the endpoint context is the Average TRB Length. This is supposed to be the average of the total bytes in the transfer descriptor (TD), divided by the number of transfer request blocks (TRBs) it takes to describe the TD. This gives the host controller an indication of whether the driver will be enqueuing a scatter gather list with many entries comprised of small buffers, or one contiguous buffer. It also takes into account the number of extra TRBs you need for every TD. This includes No-op TRBs and Link TRBs used to link ring segments together. Some drivers may choose to chain an Event Data TRB on the end of every TD, thus increasing the average number of TRBs per TD. The Linux xHCI driver does not use Event Data TRBs. In theory, if there was an API to allow drivers to state what their bandwidth requirements are, we could set this field accurately. For now, we set it to the same number as the Max ESIT payload. The Average TRB Length should also be set for bulk and control endpoints, but I have no idea how to guess what it should be. Signed-off-by:

A SuperSpeed interrupt or isochronous endpoint can define the number of "burst transactions" it can handle in a service interval. This is indicated by the "Mult" bits in the bmAttributes of the SuperSpeed Endpoint Companion Descriptor. For example, if it has a max packet size of 1024, a max burst of 11, and a mult of 3, the host may send 33 1024-byte packets in one service interval. We must tell the xHCI host controller the number of multiple service opportunities (mults) the device can handle when the endpoint is installed. We do that by setting the Mult field of the Endpoint Context before a configure endpoint command is sent down. The Mult field is invalid for control or bulk SuperSpeed endpoints. Signed-off-by:

This patch (as1371) fixes a small bug in ohci-hcd. The HCD already knows how many ports the controller has; there's no need to go looking at the root hub's usb_device structure to find out. Especially since the root hub's maxchild value is set correctly only while the root hub is bound to the hub driver. Signed-off-by:

This patch (as1372) fixes a bug in the routine that chooses the default configuration to install when a new USB device is detected. The algorithm is supposed to look for a config whose first interface is for a non-vendor-specific class. But the way it's currently written, it will also accept a config with no interfaces at all, which is not very useful. (Believe it or not, such things do exist.) Signed-off-by:

Commit 18eabe23 introduced DMA buffer ownership. Fix tusb6010 accordingly. To compile, also dummy musb_platform_save and restore functions need to be added. Also change the order of musb_read_fifo() to happen after dma_cache_maint to have the DMA operations completed before moving the remaining unaligned bytes with PIO. The DMA access and PIO touch different areas of the FIFO, so this change only makes the code a bit easier to follow. Tested on n810 and g_ether with variable size ping test. The test seems to fail for some ping sizes, but that seems to be a different problem. Signed-off-by:

The bypassing of this test is a leftover from 2.4 vintage kernels, and is no longer appropriate, or even used by KGDB. Currently KGDB uses probe_kernel_write() for all access to memory via the KGDB core, so it can simply be deleted. This fixes CVE-2010-1446.

On low memory boxes or those with highmem, kernel can OOM before the background reclaims inodes via xfssyncd. Add a shrinker to run inode reclaim so that it inode reclaim is expedited when memory is low. This is more complex than it needs to be because the VM folk don't want a context added to the shrinker infrastructure. Hence we need to add a global list of XFS mount structures so the shrinker can traverse them. Signed-off-by:
