From 541768b08a400d9d292cfd9c898401b8178856ac Mon Sep 17 00:00:00 2001 From: Vignesh R Date: Thu, 29 Jun 2017 10:55:14 +0530 Subject: usb: dwc3: core: Call dwc3_core_get_phy() before initializing phys commit f54edb539c116 ("usb: dwc3: core: initialize ULPI before trying to get the PHY") moved call to dwc3_core_get_phy() from dwc3_probe() to dwc3_core_init() after dwc3_core_soft_reset(). But dwc3_core_soft_reset() calls phy_init(), therefore dwc3_core_get_phy() needs to be called before dwc3_core_soft_reset(). Fix this by moving call to dwc3_core_get_phy() before dwc3_core_soft_reset().

But OMAP DWC3 driver uses this flag. As per commit 12a7f17fac5b ("usb: dwc3: omap: fix race of pm runtime with irq handler in probe") that introduced this flag, PM runtime can race with IRQ handler when deferred probing happens due to extcon, therefore IRQ_NOAUTOEN needs to be set so that irq is not enabled until extcon is registered. Remove setting of IRQ_NOAUTOEN and move the registration of shared irq to a point after dwc3_omap_extcon_register() and of_platform_populate(). This avoids possibility of probe deferring and above said race condition.

However, this poses a problem in case the request is dequeued or the endpoint is disabled before the mapping is done as that would lead to dwc3_gadget_giveback() unconditionally calling usb_gadget_unmap_request_for_dev() with an invalid request->dma handle. Depending on the platform's DMA implementation the unmap operation could result in a panic. Since we know a successful mapping is a prerequisite for getting a TRB, the unmap can be conditionally called only when req->trb is non-NULL.

HW completes the command execution and reports "Context State Error" completion code. This is as per the spec. However HW on receiving the second command additionally marks EP to Flow control state in HW which is RTL bug. This bug causes the HW not to respond to any further doorbells that are rung by the driver. This makes the EP to not functional anymore and causes gross functional failures. As a workaround, not to hit this problem, it's better to check the EP state and issue a stop EP command only when the EP is in running state.

Leaving it uncleared caused get_port_status() to timeout after 20000ms while waiting to get the final port event interrupt for resume -> U0 state change. This is a targeted fix for a specific case where we get a port resume event racing with xhci resume. The port event interrupt handler notices xHC is not yet running and bails out early, leaving PLC uncleared. The whole xhci port resuming needs more attention, but while working on it it anyways makes sense to always ensure PLC is cleared in get_port_status before setting a new link state and waiting for its completion.

The old code used a softirq for handling request completions, but blk-mq can handle completions in the caller's context. This may cause a problem for usb-storage, because it invokes the ->scsi_done callback while holding the host lock, and the completion routine sometimes tries to acquire the same lock (when running the error handler, for example). The consequence is that the existing code will sometimes deadlock upon error completion of a SCSI command (with a lockdep warning). This is easy enough to fix, since usb-storage doesn't really need to hold the host lock while the callback runs. It was simpler to write it that way, but moving the call outside the locked region is pretty easy and there's no downside. That's what this patch does.

Currently usb_hcd_flush_endpoint() passes each urb from the head of the endpoint's urb_list to the controller driver, which could make the controller driver think each urb has been programmed and take the unnecessary actions for each urb. This patch changes the behavior in usb_hcd_flush_endpoint() to pass the urbs from the tail of the list, to avoid any unnecessary actions in an controller driver.

However, the 1ms delay is needed for some use cases, for example, without the delay, reconnecting AR9271 WIFI dongle no longer works if the connection is dropped from the AP.

This is visible if the device has been using 64-bit DMA addresses, and is then switched to using 32-bit DMA addresses. The top 32 bits of the address (now zero) are ignored are replaced by the 32 bits from the *previous* programming. Sticking with 64-bit DMA always works, but doesn't seem very appropriate. A PCI reset of the device restores the normal functionality, which is done at probe time. Unfortunately, this has to be done before any quirk has been discovered, hence the intrusive nature of the fix.

As per spec correct PIDs for ISOC data transfers are: 1) For request length <= maxpacket - DATA0, 2) For maxpacket < length <= (2 * maxpacket) - DATA1, DATA0 3) For (2 * maxpacket) < length <= (3 * maxpacket) - DATA2, DATA1, DATA0. But driver always sets PCM fields based on wMaxPacketSize due to which DATA2 happens even for small requests. Fix this by setting the PCM field of trb->size depending on request length rather than fixing it to the value depending on wMaxPacketSize. Ideally it shouldn't give any issues as dwc3 will send 0-length packet for next IN token if host sends (even after receiving a short packet). Windows seems to ignore this but with MacOS frame loss observed when using f_uvc.

In SNPS USB design, the host responds to the resume request only after system gets back to S0 and the host gets to functional after the internal HW restore operation that is more than 1 second after the initial resume request from the USB device. As a workaround for specific keyboard ID(HP Keyboards), applying port reset after resume when the keyboard is plugged in.

This may lead to a device connecting at full speed instead of high speed, because when the USB stack sees that a device isn't able to enumerate at high speed, it tries to hand the connection over to a full-speed companion controller. The logic for doing this is careful to check that the device is still connected. But this check is inadequate if the device disconnects and reconnects before the check is done. The symptom is that a device works, but much more slowly than it is capable of operating. The situation was made worse recently by commit 22547c4cc4fe ("usb: hub: Wait for connection to be reestablished after port reset"), which increases the delay following a reset before a disconnect is recognized, thus giving the device more time to reconnect. This patch makes the check more robust. If the device was disconnected at any time during enumeration, we will now skip the full-speed handover.
