From mboxrd@z Thu Jan 1 00:00:00 1970 From: Lars Persson Subject: [PATCH net 0/5] dwc_eth_qos: stability fixes and support for CMA Date: Mon, 29 Feb 2016 16:22:29 +0100 Message-ID: Cc: linux-kernel@vger.kernel.org, Lars Persson To: netdev@vger.kernel.org Return-path: Received: from bes.se.axis.com ([195.60.68.10]:53847 "EHLO bes.se.axis.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1752059AbcB2PXe (ORCPT ); Mon, 29 Feb 2016 10:23:34 -0500 Sender: netdev-owner@vger.kernel.org List-ID: This series has bug fixes for the dwc_eth_qos ethernet driver. Mainly two stability fixes for problems found by Rabin Vincent: - Successive starts and stops of the interface would trigger a DMA reset timeout. - A race condition in the TX DMA handling could trigger a netdev watchdog timeout. The memory allocation was improved to support use of the CMA as DMA allocator backend. Lars Persson (2): dwc_eth_qos: release descriptors outside netif_tx_lock dwc_eth_qos: do phy_start before resetting hardware Rabin Vincent (3): dwc_eth_qos: fix race condition in dwceqos_start_xmit dwc_eth_qos: use GFP_KERNEL in dma_alloc_coherent() dwc_eth_qos: use DWCEQOS_MSG_DEFAULT drivers/net/ethernet/synopsys/dwc_eth_qos.c | 45 ++++++++++++++++++++--------- 1 file changed, 31 insertions(+), 14 deletions(-) -- 2.1.4
