Update the qTD traversal paths to use ehci_get_desc_addr()\nwhen following link pointers.\n\nAppendix B also defines high dword fields for qTD buffer pointers.\nAdd bufptr_hi[5] to EHCIqtd and extend qTD fetch and QH overlay\nhandling to load and propagate the high buffer pointer fields.\n\nWhen 64-bit capability is disabled, descriptor and buffer addresses\nremain 32-bit and existing behaviour is unchanged.\n\nSigned-off-by: Jamin Lin <jamin_lin@aspeedtech.com>\nReviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org>\n---\n hw/usb/hcd-ehci.h | 1 +\n hw/usb/hcd-ehci.c | 19 ++++++++++++-------\n 2 files changed, 13 insertions(+), 7 deletions(-)", "diff": "diff --git a/hw/usb/hcd-ehci.h b/hw/usb/hcd-ehci.h\nindex 3428839ec6..fc66aacd9f 100644\n--- a/hw/usb/hcd-ehci.h\n+++ b/hw/usb/hcd-ehci.h\n@@ -139,6 +139,7 @@ typedef struct EHCIqtd {\n uint32_t bufptr[5]; /* Standard buffer pointer */\n #define QTD_BUFPTR_MASK 0xfffff000\n #define QTD_BUFPTR_SH 12\n+ uint32_t bufptr_hi[5];\n } EHCIqtd;\n \n /* QH overlay: altnext_qtd, token, bufptr[5], bufptr_hi[5] */\ndiff --git a/hw/usb/hcd-ehci.c b/hw/usb/hcd-ehci.c\nindex 5ffd4c9885..e82e0f625c 100644\n--- a/hw/usb/hcd-ehci.c\n+++ b/hw/usb/hcd-ehci.c\n@@ -472,7 +472,8 @@ static bool ehci_verify_qtd(EHCIPacket *p, EHCIqtd *qtd)\n (p->qtd.next != qtd->next)) ||\n (!NLPTR_TBIT(p->qtd.altnext) && (p->qtd.altnext != qtd->altnext)) ||\n p->qtd.token != qtd->token ||\n- p->qtd.bufptr[0] != qtd->bufptr[0]) {\n+ p->qtd.bufptr[0] != qtd->bufptr[0] ||\n+ p->qtd.bufptr_hi[0] != qtd->bufptr_hi[0]) {\n return false;\n } else {\n return true;\n@@ -1200,6 +1201,7 @@ static int ehci_qh_do_overlay(EHCIQueue *q)\n \n for (i = 0; i < 5; i++) {\n q->qh.bufptr[i] = p->qtd.bufptr[i];\n+ q->qh.bufptr_hi[i] = p->qtd.bufptr_hi[i];\n }\n \n if (!(q->qh.epchar & QH_EPCHAR_DTC)) {\n@@ -1233,7 +1235,8 @@ static int ehci_init_transfer(EHCIPacket *p)\n return -1;\n }\n \n- page = p->qtd.bufptr[cpage] & QTD_BUFPTR_MASK;\n+ page = ehci_get_buf_addr(p->queue->ehci, p->qtd.bufptr_hi[cpage],\n+ p->qtd.bufptr[cpage], QTD_BUFPTR_MASK);\n page += offset;\n plen = bytes;\n if (plen > 4096 - offset) {\n@@ -1727,7 +1730,7 @@ static EHCIQueue *ehci_state_fetchqh(EHCIState *ehci, int async)\n } else if ((q->qh.token & QTD_TOKEN_ACTIVE) &&\n (NLPTR_TBIT(q->qh.current_qtd) == 0) &&\n (q->qh.current_qtd != 0)) {\n- q->qtdaddr = q->qh.current_qtd;\n+ q->qtdaddr = ehci_get_desc_addr(ehci, q->qh.current_qtd);\n ehci_set_state(ehci, async, EST_FETCHQTD);\n \n } else {\n@@ -1805,14 +1808,14 @@ static int ehci_state_advqueue(EHCIQueue *q)\n */\n if (((q->qh.token & QTD_TOKEN_TBYTES_MASK) != 0) &&\n (NLPTR_TBIT(q->qh.altnext_qtd) == 0)) {\n- q->qtdaddr = q->qh.altnext_qtd;\n+ q->qtdaddr = ehci_get_desc_addr(q->ehci, q->qh.altnext_qtd);\n ehci_set_state(q->ehci, q->async, EST_FETCHQTD);\n \n /*\n * next qTD is valid\n */\n } else if (NLPTR_TBIT(q->qh.next_qtd) == 0) {\n- q->qtdaddr = q->qh.next_qtd;\n+ q->qtdaddr = ehci_get_desc_addr(q->ehci, q->qh.next_qtd);\n ehci_set_state(q->ehci, q->async, EST_FETCHQTD);\n \n /*\n@@ -1841,7 +1844,9 @@ static int ehci_state_fetchqtd(EHCIQueue *q)\n if (get_dwords(q->ehci, addr + 0, &qtd.next, 1) < 0 ||\n get_dwords(q->ehci, addr + 4, &qtd.altnext, 1) < 0 ||\n get_dwords(q->ehci, addr + 12, qtd.bufptr,\n- ARRAY_SIZE(qtd.bufptr)) < 0) {\n+ ARRAY_SIZE(qtd.bufptr)) < 0 ||\n+ get_dwords(q->ehci, addr + 32, qtd.bufptr_hi,\n+ ARRAY_SIZE(qtd.bufptr_hi)) < 0) {\n return 0;\n }\n ehci_trace_qtd(q, NLPTR_GET(q->qtdaddr), &qtd);\n@@ -1922,7 +1927,7 @@ static int ehci_fill_queue(EHCIPacket *p)\n if (NLPTR_TBIT(qtd.next) != 0) {\n break;\n }\n- qtdaddr = qtd.next;\n+ qtdaddr = ehci_get_desc_addr(q->ehci, qtd.next);\n /*\n * Detect circular td lists, Windows creates these, counting on the\n * active bit going low after execution to make the queue stop.\n", "prefixes": [ "v4", "11/17" ] }
