struct mon_bin_hdr allows for a 64-bit seconds timestamp. The code currently uses 'struct timeval' to populate the timestamp in mon_bin_hdr, which has a 32-bit seconds field and will overflow in year 2038 and beyond. This patch replaces 'struct timeval' with 'struct timespec64' which is y2038 safe. This patch is part of a larger attempt to remove instances of struct timeval and other 32-bit timekeeping (time_t, struct timespec) from the kernel.

timeval is deprecated and not y2038 safe. Its size also changes according to 32 bit/ 64 bit compilation. Replace it with 32 and 64 bit versions of its individual fields, giving two ioctls with different code values. The two ioctls are necessary to maintain the 32 bit and 64 bit userspace compatibility with a 64/32 bit kernel. Change unsigned to __u32 types for a definitive userspace interface. This is in accordance with the psABI that the unsigned type is always 32 bits. Also use motonic timer instead of real time to ensure positive delta values. Refactor usbtest_ioctl for readability to isolate the handling of the testing timing measurement. The official testusb userspace tool can be changed in a separate patch to reflect the __u32 changes as well. It can use the usbtest_param_32 struct, since 32 bit seconds is long enough for test durations.

struct timeval' uses 32-bits for its seconds field and will overflow in the year 2038 and beyond. This patch replaces the usage of 'struct timeval' in mon_get_timestamp() with timespec64 which uses a 64-bit seconds field and is y2038-safe. mon_get_timestamp() truncates the timestamp at 4096 seconds, so the correctness of the code is not affected.

So far we were using simple (legacy) GPIO functions & some poor logic to control power. It got many drawbacks: we were ignoring OF flags (GPIO_ACTIVE_LOW), we were not setting direction to output and we were assuming gpio_request success all the time. Fix it by switching to gpiod functions and adding appropriate checks.

Replace the existing two extended capability parsing helper functions with one called xhci_find_next_ext_cap(). The extended capabilities are read both in pci-quirks before xhci driver is loaded, and inside the xhci driver when adding ports. The existing helpers did not suit well for these cases and a lot of custom parsing code was needed. The new helper function simplifies these two cases a lot. The motivation for this rework was that code to support xhci debug capability needed to parse extended capabilities, and it included yet another capability parsing helper specific for its needs. With this solution it debug capability code can use this new helper as well Signed-off-by: NMathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: NGreg Kroah-Hartman <gregkh@linuxfoundation.org>

There some vendor quirks for MTK xhci host controller: 1. It defines some extra SW scheduling parameters for HW to minimize the scheduling effort for synchronous and interrupt endpoints. The parameters are put into reseved DWs of slot context and endpoint context. 2. Its IMODI unit for Interrupter Moderation register is 8 times as much as that defined in xHCI spec. 3. Its TDS in Normal TRB defines a number of packets that remains to be transferred for a TD after processing all Max packets in all previous TRBs.

This patch adds a new warning message to ehci-hcd. The warning is triggered whenever the driver finds that the hardware has set the Active bit in a QH at a time when the driver expects the QH to be completely idle. Such bugs have been observed by users in the past, and since they can lead to serious problems (such as inability to unlink an URB that never completes), it would be good to know about them when they occur. This won't fix these bugs; that's a bigger job for a later patch. But success isn't guaranteed, since this depends on aspects of the hardware which are not documented in the EHCI spec or for which the spec's recommendations are clearly unworkable. It therefore seems worthwhile to check for these bugs proactively.

This patch enhances the "async" debugfs file in ehci-hcd by printing out several additional fields in the hardware-accessible data structures. These fields are important for determining the hardware's view of the async schedule, in particular, the addresses of the current and next qTDs for each QH along with the start address of each qTD's data buffer.

This patch improves the usbfs_snoop debugging facility by adding messages for a couple of significant events which, up to now, have not been logged. The events are reaping and discarding (i.e., cancelling) an URB. The debugging messages include the userspace address of the URB being reaped or discarded. The reaping messages have to be added in four places, in order to handle blocking and non-blocking reaps in both normal and 32-bit compatibility mode.

The usbfs_snoop facility can be very useful for debugging problems involving usbfs. However, it always prints out the entire contents of every URB. When dealing with large quantities of data, this can be less than helpful. This patch ameliorates the situation by adding a module parameter to usbcore for controlling the maximum number of bytes to print when snooping an URB. This makes debugging much easier. For backward compatibility, the default value is set unreasonably high. Signed-off-by: NAlan Stern <stern@rowland.harvard.edu> Signed-off-by: NGreg Kroah-Hartman <gregkh@linuxfoundation.org>
