From 27c6e526f34760a9c48a90112242b7165064fa85 Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Fri, 24 Mar 2006 03:18:26 -0800 Subject: [PATCH] rio driver rework continued #1 More header cleanups, strip out typedefs and remove cruft. There are a lot of magic macros that can go and also a great deal of abuse of volatile that is not needed any more as this patch set cleans up the misuse of pointer access to ISA and PCI space. It now builds cleanly on 64bit, although there is more work left to do Signed-off-by: Alan Cox Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- drivers/char/rio/cmdpkt.h | 48 ++++++++++++++--------------- drivers/char/rio/daemon.h | 67 +++++++++++++++++++---------------------- drivers/char/rio/host.h | 56 +++++++++++++++++----------------- drivers/char/rio/link.h | 4 +-- drivers/char/rio/linux_compat.h | 41 +------------------------ drivers/char/rio/port.h | 2 +- drivers/char/rio/riodrvr.h | 48 ++++++++++++++--------------- drivers/char/rio/rup.h | 4 +-- drivers/char/rio/top.h | 4 +-- drivers/char/rio/typdef.h | 11 +++---- 10 files changed, 118 insertions(+), 167 deletions(-) (limited to 'drivers') diff --git a/drivers/char/rio/cmdpkt.h b/drivers/char/rio/cmdpkt.h index b6445d3f141..357ae572243 100644 --- a/drivers/char/rio/cmdpkt.h +++ b/drivers/char/rio/cmdpkt.h @@ -118,45 +118,45 @@ struct PktCmd_M { union { struct { struct { - uchar PcCommand; + u8 PcCommand; union { - uchar PcPhbNum; - uchar PcLinkNum; - uchar PcIDNum; + u8 PcPhbNum; + u8 PcLinkNum; + u8 PcIDNum; } U0; } CmdHdr; struct { - ushort NumPackets; - ushort LoadBase; - ushort CodeSize; + u16 NumPackets; + u16 LoadBase; + u16 CodeSize; } PcBootSequence; } S1; struct { - ushort PcSequence; - uchar PcBootData[RTA_BOOT_DATA_SIZE]; + u16 PcSequence; + u8 PcBootData[RTA_BOOT_DATA_SIZE]; } S2; struct { - ushort __crud__; - uchar PcUniqNum[4]; /* this is really a uint. */ - uchar PcModuleTypes; /* what modules are fitted */ + u16 __crud__; + u8 PcUniqNum[4]; /* this is really a uint. */ + u8 PcModuleTypes; /* what modules are fitted */ } S3; struct { - ushort __cmd_hdr__; - uchar __undefined__; - uchar PcModemStatus; - uchar PcPortStatus; - uchar PcSubCommand; - ushort PcSubAddr; - uchar PcSubData[64]; + u16 __cmd_hdr__; + u8 __undefined__; + u8 PcModemStatus; + u8 PcPortStatus; + u8 PcSubCommand; + u16 PcSubAddr; + u8 PcSubData[64]; } S4; struct { - ushort __cmd_hdr__; - uchar PcCommandText[1]; - uchar __crud__[20]; - uchar PcIDNum2; /* Tacked on end */ + u16 __cmd_hdr__; + u8 PcCommandText[1]; + u8 __crud__[20]; + u8 PcIDNum2; /* Tacked on end */ } S5; struct { - ushort __cmd_hdr__; + u16 __cmd_hdr__; struct Top Topology[LINKS_PER_UNIT]; } S6; } U1; diff --git a/drivers/char/rio/daemon.h b/drivers/char/rio/daemon.h index 28a991bd4fe..5818a8aa46e 100644 --- a/drivers/char/rio/daemon.h +++ b/drivers/char/rio/daemon.h @@ -45,15 +45,15 @@ static char *_daemon_h_sccs_ = "@(#)daemon.h 1.3"; */ struct Error { - uint Error; - uint Entry; - uint Other; + unsigned int Error; + unsigned int Entry; + unsigned int Other; }; struct DownLoad { char *DataP; - uint Count; - uint ProductCode; + unsigned int Count; + unsigned int ProductCode; }; /* @@ -68,69 +68,64 @@ struct DownLoad { #endif struct PortSetup { - uint From; /* Set/Clear XP & IXANY Control from this port.... */ - uint To; /* .... to this port */ - uint XpCps; /* at this speed */ + unsigned int From; /* Set/Clear XP & IXANY Control from this port.... */ + unsigned int To; /* .... to this port */ + unsigned int XpCps; /* at this speed */ char XpOn[MAX_XP_CTRL_LEN]; /* this is the start string */ char XpOff[MAX_XP_CTRL_LEN]; /* this is the stop string */ - uchar IxAny; /* enable/disable IXANY */ - uchar IxOn; /* enable/disable IXON */ - uchar Lock; /* lock port params */ - uchar Store; /* store params across closes */ - uchar Drain; /* close only when drained */ + u8 IxAny; /* enable/disable IXANY */ + u8 IxOn; /* enable/disable IXON */ + u8 Lock; /* lock port params */ + u8 Store; /* store params across closes */ + u8 Drain; /* close only when drained */ }; struct LpbReq { - uint Host; - uint Link; + unsigned int Host; + unsigned int Link; struct LPB *LpbP; }; struct RupReq { - uint HostNum; - uint RupNum; + unsigned int HostNum; + unsigned int RupNum; struct RUP *RupP; }; struct PortReq { - uint SysPort; + unsigned int SysPort; struct Port *PortP; }; struct StreamInfo { - uint SysPort; -#if 0 - queue_t RQueue; - queue_t WQueue; -#else + unsigned int SysPort; int RQueue; int WQueue; -#endif }; struct HostReq { - uint HostNum; + unsigned int HostNum; struct Host *HostP; }; struct HostDpRam { - uint HostNum; + unsigned int HostNum; struct DpRam *DpRamP; }; struct DebugCtrl { - uint SysPort; - uint Debug; - uint Wait; + unsigned int SysPort; + unsigned int Debug; + unsigned int Wait; }; struct MapInfo { - uint FirstPort; /* 8 ports, starting from this (tty) number */ - uint RtaUnique; /* reside on this RTA (unique number) */ + unsigned int FirstPort; /* 8 ports, starting from this (tty) number */ + unsigned int RtaUnique; /* reside on this RTA (unique number) */ }; struct MapIn { - uint NumEntries; /* How many port sets are we mapping?
