hi all: when I trace xhci_queue_isoc_tx, I found ISO TD should look like ISO TRB --> Normal TRB --> Normal TRB But when I dump ep segment during Iso transfer I get below result 1. Why most of them are ISO TRBs? 2. Why there is only 1 normal TRB appreciate your help in advance, ep ring segment: platform-xhci platform-xhci.0: @000000002796e000 279c0000 00000000 00000bf4 80021625 platform-xhci platform-xhci.0: @000000002796e010 279c0bf4 00000000 00000bf4 80021625 platform-xhci platform-xhci.0: @000000002796e020 279c17e8 00000000 00000bf4 80021625 platform-xhci platform-xhci.0: @000000002796e030 279c23dc 00000000 00000bf4 80021625 platform-xhci platform-xhci.0: @000000002796e040 279c2fd0 00000000 00000bf4 80021625 platform-xhci platform-xhci.0: @000000002796e050 279c3bc4 00000000 00000bf4 80021625 platform-xhci platform-xhci.0: @000000002796e060 279c47b8 00000000 00000bf4 80021625 platform-xhci platform-xhci.0: @000000002796e070 279c53ac 00000000 00000bf4 80021625 platform-xhci platform-xhci.0: @000000002796e080 279c5fa0 00000000 00000bf4 80021625 platform-xhci platform-xhci.0: @000000002796e090 279c6b94 00000000 00000bf4 80021625 platform-xhci platform-xhci.0: @000000002796e0a0 279c7788 00000000 00000bf4 80021625 platform-xhci platform-xhci.0: @000000002796e0b0 279c837c 00000000 00000bf4 80021625 platform-xhci platform-xhci.0: @000000002796e0c0 279c8f70 00000000 00000bf4 80021625 platform-xhci platform-xhci.0: @000000002796e0d0 279c9b64 00000000 00000bf4 80021625 platform-xhci platform-xhci.0: @000000002796e0e0 279ca758 00000000 00000bf4 80021625 platform-xhci platform-xhci.0: @000000002796e0f0 279cb34c 00000000 00000bf4 80021625 platform-xhci platform-xhci.0: @000000002796e100 279cbf40 00000000 00000bf4 80021625 platform-xhci platform-xhci.0: @000000002796e110 279ccb34 00000000 00000bf4 80021625 platform-xhci platform-xhci.0: @000000002796e120 279cd728 00000000 00000bf4 80021625 platform-xhci platform-xhci.0: @000000002796e130 279ce31c 00000000 00000bf4 80021625 platform-xhci platform-xhci.0: @000000002796e140 279cef10 00000000 00000bf4 80021625 //ISO TRB platform-xhci platform-xhci.0: @000000002796e150 279cfb04 00000000 000404fc 80021415 //ISO TRB platform-xhci platform-xhci.0: @000000002796e160 279d0000 00000000 000006f8 00000625 //Normal TRB platform-xhci platform-xhci.0: @000000002796e170 279d06f8 00000000 00000bf4 80021625 platform-xhci platform-xhci.0: @000000002796e180 279d12ec 00000000 00000bf4 80021625 platform-xhci platform-xhci.0: @000000002796e190 279d1ee0 00000000 00000bf4 80021625 -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
