* usb: gadget: storage: fix mass storage gadgets to work with Synopsys UDCPaul Zimmerman2011-10-132-18/+18
| | | | | | | | | | | | | | | | | The Synopsys USB device controller requires all OUT transfer request lengths to be aligned to max packet size. The mass storage gadgets do not meet this requirement for Super Speed. The gadgets already have a function which performs this alignment for CBW packets, so use it for data packets too. The alternative would be to implement bounce buffers in the DWC3 driver, but that could have a significant impact on performance. This version is based upon a more-correct patch written by Alan Stern. Signed-off-by: Paul Zimmerman <paulz@synopsys.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
* USB: gadget: f_midi: allow a dynamic number of input and output portsDaniel Mack2011-10-132-108/+191
| | | | | | | | | | | | | | The code in the MIDI gadget was already sort of prepared for multi-port configuration, so the streaming logic itself didn't need much tweaking. However, the descriptors change when the number of ports do, and so some rework of the the preparation algorithms were necessary. Successfully tested on Linux and Max OS X hosts for both input and output streams.

| * USB: gadget: storage: remove alignment assumptionAlan Stern2011-09-092-81/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1481) fixes a problem affecting g_file_storage and g_mass_storage when running at SuperSpeed. The two drivers currently assume that the bulk-out maxpacket size can evenly divide the SCSI block size, which is 512 bytes. But SuperSpeed bulk endpoints have a maxpacket size of 1024, so the assumption is no longer true. This patch removes that assumption from the drivers, by getting rid of a small optimization (they try to align VFS reads and writes on page cache boundaries). If a command's starting logical block address is 512 bytes below the end of a page, it's not okay to issue a USB command for just those 512 bytes when the maxpacket size is 1024 -- it would result in either babble (for an OUT transfer) or a short packet (for an IN transfer). Also, for backward compatibility, the test for writes extending beyond the end of the backing storage has to be changed. If the host tries to do this, we should accept the data that fits in the backing storage and ignore the rest. Because the storage's end may not align with a USB packet boundary, this means we may have to accept a USB OUT transfer that extends beyond the end of the storage and then write out only the part of the data that fits.

| * usb: gadget: storage: adapt logic block size to bound block devicesPeiyu Li2011-09-093-57/+79
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now the mass storage driver has fixed logic block size of 512 bytes. The mass storage gadget read/write bound devices only through VFS, so the bottom level devices actually are just RAW devices to the driver and connected PC. As a RAW, hosts can always format, read and write it right in 512 bytes logic block and don't care about the actual logic block size of devices bound to the gadget. But if we want to share the bound block device partition between target board and PC, in case the logic block size of the bound block device is 4KB, we execute the following steps: 1. connect a board with mass storage gadget to PC(the board has set one partition of on-board block device as file name of the mass storage) 2. PC format the mass storage to VFAT by default logic block size and read/write it 3. disconnect boards from PC 4. target board mount the partition as VFAT Step 4 will fail since kernel on target thinks the logic block size of the bound partition as 4KB. A typical error is "FAT: logical sector size too small for device (logical sector size = 512)" If we execute opposite steps: 1. format the partition to VFAT on target board and read/write this partition 2. connect the board to Windows PC as usb mass storage gadget, windows will think the disk is not formatted So the conclusion is that only as a gadget, the mass storage driver has no any problem. But being shared VFAT or other filesystem on PC and target board, it will fail. This patch adapts logic block size to bound block devices and fix the issue.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In a few places in the kernel, the code prints a human-readable USB device speed (eg. "high speed"). This involves a switch statement sometimes wrapped around in ({ ... }) block leading to code repetition. To mitigate this issue, this commit introduces usb_speed_string() function, which returns a human-readable name of provided speed. It also changes a few places switch was used to use this new function. This changes a bit the way the speed is printed in few instances at the same time standardising it.

Several other parameters can be configured like amount of FIFO space, amount of TX and RX endpoints, amount of Host Interrupters, etc. The current driver has been validated with a virtual model of version 1.73a of that core and with an FPGA burned with version 1.83a of the DRD core. We have support for PCIe bus, which is used on FPGA prototyping, and for the OMAP5, more adaptation (or glue) layers can be easily added and the driver is half prepared to handle any possible configuration the HW engineer has chosen considering we have the information on one of the GHWPARAMS registers to do runtime checking of certain features. More runtime checks can, and should, be added in order to make this driver even more flexible with regards to number of endpoints, FIFO sizes, transfer types, etc. While this supports only the device side, for now, we will add support for Host side (xHCI - see the updated series Sebastian has sent [1]) and OTG after we have it all stabilized.

| | | | | | | | | | | | | | | | | | | | | | | | This is a patch to fix an issue with the HID gadget which, at the moment, returns STALL on a HID descriptor request. Essentially, the patch changes the hid gadget such that a request for the HID descriptor is handled by copying the descriptor into the response buffer, rather than falling through the default case, in which the request is answered by a STALL.

| * [media] v4l2-event/ctrls/fh: allocate events per fh and per type instead of ↵Hans Verkuil2011-07-271-11/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | just per-fh The driver had to decide how many events to allocate when the v4l2_fh struct was created. It was possible to add more events afterwards, but there was no way to ensure that you wouldn't miss important events if the event queue would fill up for that filehandle. In addition, once there were no more free events, any new events were simply dropped on the floor. For the control event in particular this made life very difficult since control status/value changes could just be missed if the number of allocated events and the speed at which the application read events was too low to keep up with the number of generated events. The application would have no idea what the latest state was for a control since it could have missed the latest control change. So this patch makes some major changes in how events are allocated. Instead of allocating events per-filehandle they are now allocated when subscribing an event. So for that particular event type N events (determined by the driver) are allocated. Those events are reserved for that particular event type. This ensures that you will not miss events for a particular type altogether. In addition, if there are N events in use and a new event is raised, then the oldest event is dropped and the new one is added. So the latest event is always available. This can be further improved by adding the ability to merge the state of two events together, ensuring that no data is lost at all. This will be added in the next patch. This also makes it possible to allow the user to determine the number of events that will be allocated. This is not implemented at the moment, but would be trivial.

| * [media] v4l2-events/fh: merge v4l2_events into v4l2_fhHans Verkuil2011-07-271-8/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Drivers that supported events used to be rare, but now that controls can also raise events this will become much more common since almost all drivers have controls. This means that keeping struct v4l2_events as a separate struct make no more sense. Merging it into struct v4l2_fh simplifies things substantially as it is now an integral part of the filehandle struct.
