EFI = Extensible FirmwareInterface

• A new standard from Intel replacing the BIOS • EFI firmware on the system

− Includes a user interface called the “shell”− EFI commands native in the firmware− Interface to the system hardware

• Consists of three major components:− 1) The EFI Firmware core, − 2) EFI System Partition (ESP)

The OS creates the EFI System PartitionOS loader image is in the EFI System PartitionValue-add software utilities/tools may be

added during install or later− 3) EFI boot manager

Applikations Portierung auf IA 64

• eigene, selbstgeschriebene Applikationen

OpenVMS ISV porting status

As of August 1, 2005, 886 apps and services from 424 partners were committed to be ported – 386 are available already. Here are some of the companies who are ready now or will be ready soon.


www.decus.de 14

Porting to OpenVMS I64• Porting ist fast immer problemslos• In den meisten Fällen nur

• re-compile• re-link• re-test

erforderlich

−Privileged code erfordert etwas mehr Aufwandlinesof C code did not requireeven one change

Porting to OpenVMS I64• MANY!!! Things have changed in the O/S−Different primitives −Different default floating point standard−New compilers−New image format−New calling standard −No console/PAL code

Most changes are transparent but these changes might affect your application


www.decus.de 15

Porting to OpenVMS I64

very important :

1. update your Alpha to the latest Version ofOpenVMS, Compiler, layered products

2. compile and link your application on this platform

3. compile and link on IA64

„.. porting to ALPHA OpenVMS V-8.2 ...“

Most of the problems encountered were due to − updates to the OS and compilers, not due to Itanium−Tighter compiler standards−Changes in the CRTL−Changes to DECthreads - PTHREAD_USE_D4

• When has your application been rebuilt last ?− “The last time we built this was in 1997”

• An application isn’t correct because it runs on Alpha−Some partners uncovered day-one bugs


www.decus.de 16

Some key items to start with• FORTRAN 77 not available on OpenVMS I64− need to migrate from F77 to F90− on Alpha prior to starting the port

• MACRO-32 (VAX MACRO)−Read the Macro-32 Porting Guide first−Pay attention to CALL LINKAGES

• MACRO-64 code MUST be rewritten• Use supported, documented interfaces• Tricks will work, but may be difficult to port

Starting on IPF …

• Up SYSUAF quotas on IPF for compiles and links− BYTLM, FILLM, WSDEF, WSQUO, WSEXTENT, PGFLQUOT− Multiply by 5 then adjust

• Porting is really easy• Many partners were successful


www.decus.de 17

Conditionalized code• This is the first (and easiest) step to take−Usually, IA64 should take what used to be the

Alpha code path.• In some cases, IA64 specific code path should be added

#include <stdio.h>#include <arch_defs>void main(){#ifdef __vax

printf("This is the VAX codepath");#endif#ifdef __alpha

printf("This is not the VAX codepath");}

Conditionalized code• Macro

IEEE floating- point• Itanium supports only IEEE floating-point in hardware

• On IA64 - IEEE floating-point is the default floating point format for the compilers.−VAX floating point formats supported when

specified as a switch to the compilers−The compilers generate code to call conversion

routines (performance hit).

IEEE floating- point• To use IEEE change the source to use S & T versions of the APIs.−Some functions (like sin, cos,….) already know

how to handle IEEE and require no changes to the application.

Q: My application uses F-float. I’m currently porting it to I64, I’m excited enough about the new architecture and I don’t want to make any source changes for now. What can I do?

A: Have no fear….HP OpenVMS engineering are here…Let’s take a look at a real example……


www.decus.de 20

$ ty float_test.c#include <stdio.h>#include <libdtdef.h>#include <descrip>#include <ssdef>

// prototypesint lib$cvtf_to_internal_time();int sys$fao();int lib$put_output();int lib$signal();

static $DESCRIPTOR (fao_desc, "Converted delta time: !%T");

main () {

float f1;unsigned long long int delta1;int status;char output[50]={0};struct dsc$descriptor_s outdesc;short int length;

//init the descriptoroutdesc.dsc$w_length = sizeof(output);outdesc.dsc$a_pointer = (char *)&output;outdesc.dsc$b_class = DSC$K_CLASS_S;outdesc.dsc$b_dtype = DSC$K_DTYPE_T;

f1 = 156.45;

printf("This program converts %f seconds to delta time\n", f1);

status = lib$cvtf_to_internal_time(&LIB$K_DELTA_SECONDS_F, &f1, &delta1);

if (!(status&1))lib$signal(status);

if ((sys$fao(&fao_desc,&length,&outdesc,&delta1))&1)lib$put_output(&outdesc);

}

IEEE floating- point• On IA64, the default value for the /FLOAT qualifier is

IEEE_FLOAT. This program relies on the binary representation of the floating point value and therefore it fails on IA64.

• Compiled on IA64 with /FLOAT=G_FLOAT forced the compiler to use the default Alpha representation. No code changes are required in this case but there is some runtime cost.

• To use IEEE floating point representation, this program should be modified to use LIB$CVTS_TO_INTERNAL_TIME

• LIB$WAIT is another common example where floating point conversion may become an issue…let’s take a look….

#include <stdio.h>

The default floating point format used by LIB$WAIT is

F_FLOAT, which does not match the default floating point

format used on I64 (S_FLOAT)


www.decus.de 23

Here is a modified version that will work on bothplatforms, using the native floating point formats

I64> ty wait_common.c#include <stdio.h>#include <arch_defs>#include <libwaitdef>main(){float wait=7.0;#ifdef __alpha

int mask = LIB$K_VAX_F;#endif#ifdef __ia64

int mask = LIB$K_IEEE_S;#endif

printf("Waiting 7 seconds\n");lib$wait(&wait,0,&mask);printf("I'm done wainting..ciao...\n");

return 0;}

IMACRO • On I64 the calling standard changed− We now use Intel’s software conventions− IA64 only preserves register R4-R7 across routine calls

(Alpha preserves R2-R15)− For programs written in high-level languages (like

C,Bliss) this difference is not visible.− When MACRO-32 programs added you have to start

worrying about how to pass register parameters between languages.

− High-level languages might trash a register IMACRO assumed to be preserved (and vice versa)

− Please reference the IMACRO porting guide for more details
