From 559fb51ba7e66fe298b8355fabde1275b7def35f Mon Sep 17 00:00:00 2001 From: Scott Bardone Date: Thu, 23 Jun 2005 01:40:19 -0400 Subject: Update Chelsio gige net driver. - Use extern prefix for functions required. - Removed a lot of wrappers, including t1_read/write_reg_4. - Removed various macros, using native kernel calls now. - Enumerated various #defines. - Removed a lot of shared code which is not currently used in "NIC only" mode. - Removed dead code. Documentation/networking/cxgb.txt: - Updated release notes for version 2.1.1 drivers/net/chelsio/ch_ethtool.h - removed file, no longer using ETHTOOL namespace. drivers/net/chelsio/common.h - moved code from osdep.h to common.h - added comment to #endif indicating which symbol it closes. drivers/net/chelsio/cphy.h - removed dead code. - added comment to #endif indicating which symbol it closes. drivers/net/chelsio/cxgb2.c - use DMA_{32,64}BIT_MASK in include/linux/dma-mapping.h. - removed unused code. - use printk message for link info resembling drivers/net/mii.c. - no longer using the MODULE_xxx namespace. - no longer using "pci_" namespace. - no longer using ETHTOOL namespace. drivers/net/chelsio/cxgb2.h - removed file, merged into common.h drivers/net/chelsio/elmer0.h - removed dead code. - added various enums. - added comment to #endif indicating which symbol it closes. drivers/net/chelsio/espi.c - removed various macros, using native kernel calls now. - removed a lot of wrappers, including t1_read/write_reg_4. drivers/net/chelsio/espi.h - added comment to #endif indicating which symbol it closes. drivers/net/chelsio/gmac.h - added comment to #endif indicating which symbol it closes. drivers/net/chelsio/mv88x201x.c - changes to sync with Chelsio TOT. drivers/net/chelsio/osdep.h - removed file, consolidation. osdep was used to translate wrapper functions since our code supports multiple OSs. removed wrappers. drivers/net/chelsio/pm3393.c - removed various macros, using native kernel calls now. - removed a lot of wrappers, including t1_read/write_reg_4. - removed unused code. drivers/net/chelsio/regs.h - added a few register entries for future and current feature support. - added comment to #endif indicating which symbol it closes. drivers/net/chelsio/sge.c - rewrote large portion of scatter-gather engine to stabilize performance. - using u8/u16/u32 kernel types instead of __u8/__u16/__u32 compiler types. drivers/net/chelsio/sge.h - rewrote large portion of scatter-gather engine to stabilize performance. - added comment to #endif indicating which symbol it closes. drivers/net/chelsio/subr.c - merged tp.c into subr.c - removed various macros, using native kernel calls now. - removed a lot of wrappers, including t1_read/write_reg_4. - removed unused code. drivers/net/chelsio/suni1x10gexp_regs.h - modified copyright and authorship of file. - added comment to #endif indicating which symbol it closes. drivers/net/chelsio/tp.c - removed file, merged into subr.c. drivers/net/chelsio/tp.h - removed file. include/linux/pci_ids.h - patched to include PCI_VENDOR_ID_CHELSIO 0x1425, removed define from our code. --- drivers/net/chelsio/sge.h | 48 ++++++++++++++++++++++++++++++++++++----------- 1 file changed, 37 insertions(+), 11 deletions(-) (limited to 'drivers/net/chelsio/sge.h') diff --git a/drivers/net/chelsio/sge.h b/drivers/net/chelsio/sge.h index 140f896def6..434b2558685 100644 --- a/drivers/net/chelsio/sge.h +++ b/drivers/net/chelsio/sge.h @@ -1,8 +1,8 @@ /***************************************************************************** * * * File: sge.h * - * $Revision: 1.7 $ * - * $Date: 2005/03/23 07:15:59 $ * + * $Revision: 1.11 $ * + * $Date: 2005/06/21 22:10:55 $ * * Description: * * part of the Chelsio 10Gb Ethernet Driver. * * * @@ -36,25 +36,50 @@ * * ****************************************************************************/ -#ifndef _CHELSIO_LINUX_SGE_H_ -#define _CHELSIO_LINUX_SGE_H_ +#ifndef _CXGB_SGE_H_ +#define _CXGB_SGE_H_ #include #include #include +#ifndef IRQ_RETVAL +#define IRQ_RETVAL(x) +typedef void irqreturn_t;
