The attached patches fix these, but also bring up some questions: * How best to handle optional support? One of the patches fixes a problem of a missing system call (sys_pciconfig_iobase). In this case, the platform I was building for has no PCI, so it's not configured in. The way I fixed it was to conditionalize the syscall table. An alternate way would be to have a module which is compiled if CONFIG_PCI is *not* set (or alternately have arch/ppc/kernel/pci.c always be compiled and export the appropriate functions that just return -ENOSYS). Comments? * I have a number of boards/platforms that I support that have not been moved into 2.6. Can I just send patches for those as well? * Has anyone succeeded in building & running 2.6 (or late 2.5) on any embedded boards (8xx/8260/405)? Thanks. -- Gary Thomas MLB Associates --=-WcTWBjANnHkk6tah2nTa Content-Disposition: attachment; filename=diffs Content-Type: text/x-patch; name=diffs; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit Index: arch/ppc/8260_io/enet.c =================================================================== RCS file: /home/gthomas/my_cvs/develop/linuxppc-2.5/arch/ppc/8260_io/enet.c,v retrieving revision 1.1 diff -u -5 -p -r1.1 enet.c --- arch/ppc/8260_io/enet.c 12 Aug 2003 12:18:15 -0000 1.1 +++ arch/ppc/8260_io/enet.c 12 Aug 2003 13:32:35 -0000 @@ -611,10 +611,11 @@ static void set_multicast_list(struct ne static int __init scc_enet_init(void) { struct net_device *dev; struct scc_enet_private *cep; int i, j; + int err; unsigned char *eap; unsigned long mem_addr; bd_t *bd; volatile cbd_t *bdp; volatile cpm8260_t *cp; Index: arch/ppc/8260_io/uart.c =================================================================== RCS file: /home/gthomas/my_cvs/develop/linuxppc-2.5/arch/ppc/8260_io/uart.c,v retrieving revision 1.1 diff -u -5 -p -r1.1 uart.c --- arch/ppc/8260_io/uart.c 12 Aug 2003 12:18:15 -0000 1.1 +++ arch/ppc/8260_io/uart.c 12 Aug 2003 13:30:40 -0000 @@ -2389,11 +2389,11 @@ void kgdb_map_scc(void) up->smc_mrblr = RX_BUF_SIZE; /* receive buffer length */ up->smc_maxidl = RX_BUF_SIZE; } #endif -static kdev_t serial_console_device(struct console *c) +static struct tty_driver *serial_console_device(struct console *c, int *index) { *index = c->index; return serial_driver; } Index: arch/ppc/kernel/misc.S =================================================================== RCS file: /home/gthomas/my_cvs/develop/linuxppc-2.5/arch/ppc/kernel/misc.S,v retrieving revision 1.1 diff -u -5 -p -r1.1 misc.S --- arch/ppc/kernel/misc.S 12 Aug 2003 12:18:16 -0000 1.1 +++ arch/ppc/kernel/misc.S 12 Aug 2003 13:44:25 -0000 @@ -1326,13 +1326,19 @@ _GLOBAL(sys_call_table) .long sys_truncate64 .long sys_ftruncate64 .long sys_stat64 /* 195 */ .long sys_lstat64 .long sys_fstat64 +#ifdef CONFIG_PCI .long sys_pciconfig_read .long sys_pciconfig_write .long sys_pciconfig_iobase /* 200 */ +#else + .long sys_ni_syscall /* sys_pciconfig_read */ + .long sys_ni_syscall /* sys_pciconfig_write */ + .long sys_ni_syscall /* sys_pciconfig_iobase /* 200 */ +#endif .long sys_ni_syscall /* 201 - reserved - MacOnLinux - new */ .long sys_getdents64 .long sys_pivot_root .long sys_fcntl64 .long sys_madvise /* 205 */ --=-WcTWBjANnHkk6tah2nTa-- ** Sent via the linuxppc-embedded mail list.
