From 9bc30f76947b15b442f6e0ec7919baa17aea5737 Mon Sep 17 00:00:00 2001 From: hathach Date: Wed, 13 Mar 2013 21:42:19 +0700 Subject: [PATCH] add some test for usbh_hcd integration - add tests for pipe_close (while TDs are active) - add tests for device unplugged add tesst & implement the async_advance_isr to clean up "REMOVING" queue head - add helper find previous qhd - add remove qhd from async list - add is_removing field for async advance isr to clean up add pipe close for control pipe & bulk pipe (with tests) add helper get qhd from pipe_handle --- tests/test/host/ehci/test_ehci_isr.c | 43 +---- tests/test/host/ehci/test_ehci_pipe_open.c | 43 +++++ .../host/ehci/test_ehci_pipe_xfer_control.c | 1 - .../ehci/test_ehci_usbh_hcd_integration.c | 180 ++++++++++++++++++ tinyusb/common/compiler/compiler.h | 2 +- tinyusb/host/ehci/ehci.c | 110 ++++++++++- tinyusb/host/ehci/ehci.h | 2 +- tinyusb/host/usbh.c | 2 + 8 files changed, 331 insertions(+), 52 deletions(-) create mode 100644 tests/test/host/ehci/test_ehci_usbh_hcd_integration.c diff --git a/tests/test/host/ehci/test_ehci_isr.c b/tests/test/host/ehci/test_ehci_isr.c index f6b9a09e..af3fc058 100644 --- a/tests/test/host/ehci/test_ehci_isr.c +++ b/tests/test/host/ehci/test_ehci_isr.c @@ -50,15 +50,17 @@ usbh_device_info_t usbh_device_info_pool[TUSB_CFG_HOST_DEVICE_MAX+1];
