| | | | * | | | | | xen/evtchn: don't do unbind_from_irqhandler under spinlockJeremy Fitzhardinge2010-05-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | unbind_from_irqhandler can end up doing /proc operations, which can't happen under a spinlock. So before removing the IRQ handler, disable the irq under the port_user lock (masking the underlying event channel and making sure the irq handler isn't running concurrently and won't start running), then remove the handler without the lock.

When we unmap (de-allocate) the MSI/MSI-X vector(s) we need to provide the PIRQ and the vector value. What we did instead was to provide the GSI (which was zero) and the vector value, and we got these unhappy error messages: (XEN) irq.c:1575: dom0: pirq 0 not mapped [ 7.733415] unmap irq failed -22 This patches fixes this and we use the PIRQ value instead of the GSI value.

The dev_flags element of struct phy_device can be used to control these things if an appropriate value can be passed from the Ethernet driver. We run into problems however if the PHY connections are specified by the device tree. There is no way for the Ethernet driver to know what flags it should pass. If we are using the device tree, the struct phy_device will be populated with the device tree node corresponding to the PHY, and we can extract extra configuration information from there. The next question is what should the format of that information be? It is highly device specific, and the device tree representation should not be tied to any arbitrary kernel defined constants. A straight forward representation is just to specify the exact bits that should be set using the "marvell,reg-init" property: phy5: ethernet-phy@5 { reg = <5>; compatible = "marvell,88e1149r"; marvell,reg-init = /* led[0]:1000, led[1]:100, led[2]:10, led[3]:tx */ <3 0x10 0 0x5777>, /* Reg 3,16 <- 0x5777 */ /* mix %:0, led[0123]:drive low off hiZ */ <3 0x11 0 0x00aa>, /* Reg 3,17 <- 0x00aa */ /* default blink periods. */ <3 0x12 0 0x4105>, /* Reg 3,18 <- 0x4105 */ /* led[4]:rx, led[5]:dplx, led[45]:drive low off hiZ */ <3 0x13 0 0x0a60>; /* Reg 3,19 <- 0x0a60 */ }; phy6: ethernet-phy@6 { reg = <6>; compatible = "marvell,88e1118"; marvell,reg-init = /* Fix rx and tx clock transition timing */ <2 0x15 0xffcf 0>, /* Reg 2,21 Clear bits 4, 5 */ /* Adjust LED drive. */ <3 0x11 0 0x442a>, /* Reg 3,17 <- 0442a */ /* irq, blink-activity, blink-link */ <3 0x10 0 0x0242>; /* Reg 3,16 <- 0x0242 */ }; The Marvell PHYs have a page select register at register 22 (0x16), we can specify any register by its page and register number. These are the first and second word. The third word contains a mask to be ANDed with the existing register value, and the fourth word is ORed with the result to yield the new register value. The new marvell_of_reg_init function leaves the page select register unchanged, so a call to it can be dropped into the .config_init functions without unduly affecting the state of the PHY. If CONFIG_OF_MDIO is not set, there is no of_node, or no "marvell,reg-init" property, the PHY initialization is unchanged.

The fix is to set the driver's "down" flag later in the routine, after all the timers and such have exited, preventing the interrupt handler from being called and exiting early without handling the interrupt.

When an async URB is unlinked, the corresponding QH is removed from the async list. If the QH's endpoint is then disabled while the URB is being given back, ehci_endpoint_disable() won't find the QH on the async list, causing it to believe that the QH has been lost. This will lead to a memory leak at best and quite possibly to an oops. The solution is to trust usbcore not to lose track of endpoints. If the QH isn't on the async list then it doesn't need to be taken off the list, but the driver should still wait for the QH to become IDLE before disabling it. In theory this fixes Bugzilla #20182. In fact the race is so rare that it's not possible to tell whether the bug is still present. However, adding delays and making other changes to force the race seems to show that the patch works.

After a resume from suspend, the xHCI driver must restore the registers, including the command ring pointer. I had suggested that Andiry set the command ring pointer to the current command ring dequeue pointer, so that the driver wouldn't have to zero the command ring. Unfortunately, setting the command ring pointer to the current dequeue pointer won't work because the register assumes the pointer is 64-byte aligned, and TRBs on the command ring are 16-byte aligned. The lower seven bits will always be masked off, leading to the written pointer being up to 3 TRBs behind the intended pointer. Here's a log excerpt. On init, the xHCI driver places a vendor-specific command on the command ring: [ 215.750958] xhci_hcd 0000:01:00.0: Vendor specific event TRB type = 48 [ 215.750960] xhci_hcd 0000:01:00.0: NEC firmware version 30.25 [ 215.750962] xhci_hcd 0000:01:00.0: Command ring deq = 0x3781e010 (DMA) When we resume, the command ring dequeue pointer to be written should have been 0x3781e010. Instead, it's 0x3781e000: [ 235.557846] xhci_hcd 0000:01:00.0: // Setting command ring address to 0x3781e001 [ 235.557848] xhci_hcd 0000:01:00.0: `MEM_WRITE_DWORD(3'b000, 64'hffffc900100bc038, 64'h3781e001, 4'hf); [ 235.557850] xhci_hcd 0000:01:00.0: `MEM_WRITE_DWORD(3'b000, 32'hffffc900100bc020, 32'h204, 4'hf); [ 235.557866] usb usb9: root hub lost power or was reset (I can't see the results of this bug because the xHCI restore always fails on this box, and the xHCI driver re-allocates everything.) The fix is to zero the command ring and put the software and hardware enqueue and dequeue pointer back to the beginning of the ring. We do this before the system suspends, to be paranoid and prevent the BIOS from starting the host without clearing the command ring pointer, which might cause the host to muck with stale memory. (The pointer isn't required to be in the suspend power well, but it could be.) The command ring pointer is set again after the host resumes.
