Utility to dump boot timing table Coreboot and u-boot create a table of timestamps which allows to see the boot process performance. The util/cbmem/cbmem.py script allows to access the table after ChromeOS boots up and display its contents on the console. The problem is that shipping images do not include Python interpreter, so there is no way to access the table on a production machine. This change introduces a utility which is a Linux app displaying the timestamp table. Conceivably the output of this utility might be included in one of the ChromeOS :/system sections, so it was attempted to write this procedure 'fail safe', namely reporting errors and not continuing processing if something goes wrong. Including of coreboot/src .h files will allow to keep the firmware timestamp implementation and this utility in sync in the future. Test: . build the utility (run 'make' while in chroot in util/cbmem) . copy `cbmem' and 'cbmem.py' to the target . run both utilities (limiting cbmem.py output to 25 lines or so) . observe that the generated tables are identical (modulo rounding up of int division, resulting in 1 ns discrepancies in some cases) localhost var # ./cbmem 18 entries total: 1:62,080 2:64,569 (2,489) 3:82,520 (17,951) 4:82,695 (174) 8:84,384 (1,688) 9:131,731 (47,347) 10:131,821 (89) 30:131,849 (27) 40:132,618 (769) 50:134,594 (1,975) 60:134,729 (134) 70:363,440 (228,710) 75:363,453 (13) 80:368,165 (4,711) 90:370,018 (1,852) 99:488,217 (118,199) 1000:491,324 (3,107) 1100:760,475 (269,150) localhost var # ./cbmem.py | head -25 time base 4249800, total entries 18 1:62,080 2:64,569 (2,489) 3:82,520 (17,951) 4:82,695 (174) 8:84,384 (1,688) 9:131,731 (47,347) 10:131,821 (89) 30:131,849 (27) 40:132,618 (769) 50:134,594 (1,975) 60:134,729 (134) 70:363,440 (228,710) 75:363,453 (13) 80:368,165 (4,711) 90:370,018 (1,852) 99:488,217 (118,199) 1000:491,324 (3,107) 1100:760,475 (269,150) Change-Id: I013e594d4afe323106d88e7938dd40b17760621c Signed-off-by: Vadim Bendebury <vbendeb@chromium.org> Reviewed-on: http://review.coreboot.org/1759 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>

Utility to dump boot timing table Coreboot and u-boot create a table of timestamps which allows to see the boot process performance. The util/cbmem/cbmem.py script allows to access the table after ChromeOS boots up and display its contents on the console. The problem is that shipping images do not include Python interpreter, so there is no way to access the table on a production machine. This change introduces a utility which is a Linux app displaying the timestamp table. Conceivably the output of this utility might be included in one of the ChromeOS :/system sections, so it was attempted to write this procedure 'fail safe', namely reporting errors and not continuing processing if something goes wrong. Including of coreboot/src .h files will allow to keep the firmware timestamp implementation and this utility in sync in the future. Test: . build the utility (run 'make' while in chroot in util/cbmem) . copy `cbmem' and 'cbmem.py' to the target . run both utilities (limiting cbmem.py output to 25 lines or so) . observe that the generated tables are identical (modulo rounding up of int division, resulting in 1 ns discrepancies in some cases) localhost var # ./cbmem 18 entries total: 1:62,080 2:64,569 (2,489) 3:82,520 (17,951) 4:82,695 (174) 8:84,384 (1,688) 9:131,731 (47,347) 10:131,821 (89) 30:131,849 (27) 40:132,618 (769) 50:134,594 (1,975) 60:134,729 (134) 70:363,440 (228,710) 75:363,453 (13) 80:368,165 (4,711) 90:370,018 (1,852) 99:488,217 (118,199) 1000:491,324 (3,107) 1100:760,475 (269,150) localhost var # ./cbmem.py | head -25 time base 4249800, total entries 18 1:62,080 2:64,569 (2,489) 3:82,520 (17,951) 4:82,695 (174) 8:84,384 (1,688) 9:131,731 (47,347) 10:131,821 (89) 30:131,849 (27) 40:132,618 (769) 50:134,594 (1,975) 60:134,729 (134) 70:363,440 (228,710) 75:363,453 (13) 80:368,165 (4,711) 90:370,018 (1,852) 99:488,217 (118,199) 1000:491,324 (3,107) 1100:760,475 (269,150) Change-Id: I013e594d4afe323106d88e7938dd40b17760621c Signed-off-by: Vadim Bendebury <vbendeb@chromium.org> Reviewed-on: http://review.coreboot.org/1759 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>

The util/cbmem/cbmem.py script allows to access the table after ChromeOS boots up and display its contents on the console. The problem is that shipping images do not include Python interpreter, so there is no way to access the table on a production machine. This change introduces a utility which is a Linux app displaying the timestamp table. Conceivably the output of this utility might be included in one of the ChromeOS :/system sections, so it was attempted to write this procedure 'fail safe', namely reporting errors and not continuing processing if something goes wrong. Including of coreboot/src .h files will allow to keep the firmware timestamp implementation and this utility in sync in the future. Test: . build the utility (run 'make' while in chroot in util/cbmem) . copy `cbmem' and 'cbmem.py' to the target . run both utilities (limiting cbmem.py output to 25 lines or so) . observe that the generated tables are identical (modulo rounding up of int division, resulting in 1 ns discrepancies in some cases) localhost var # ./cbmem 18 entries total: 1:62,080 2:64,569 (2,489) 3:82,520 (17,951) 4:82,695 (174) 8:84,384 (1,688) 9:131,731 (47,347) 10:131,821 (89) 30:131,849 (27) 40:132,618 (769) 50:134,594 (1,975) 60:134,729 (134) 70:363,440 (228,710) 75:363,453 (13) 80:368,165 (4,711) 90:370,018 (1,852) 99:488,217 (118,199) 1000:491,324 (3,107) 1100:760,475 (269,150) localhost var # ./cbmem.py | head -25 time base 4249800, total entries 18 1:62,080 2:64,569 (2,489) 3:82,520 (17,951) 4:82,695 (174) 8:84,384 (1,688) 9:131,731 (47,347) 10:131,821 (89) 30:131,849 (27) 40:132,618 (769) 50:134,594 (1,975) 60:134,729 (134) 70:363,440 (228,710) 75:363,453 (13) 80:368,165 (4,711) 90:370,018 (1,852) 99:488,217 (118,199) 1000:491,324 (3,107) 1100:760,475 (269,150) Change-Id: I013e594d4afe323106d88e7938dd40b17760621c Signed-off-by: Vadim Bendebury <vbendeb@chromium.org> Reviewed-on: http://review.coreboot.org/1759 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>

Utility to dump boot timing table Coreboot and u-boot create a table of timestamps which allows to see the boot process performance. The util/cbmem/cbmem.py script allows to access the table after ChromeOS boots up and display its contents on the console. The problem is that shipping images do not include Python interpreter, so there is no way to access the table on a production machine. This change introduces a utility which is a Linux app displaying the timestamp table. Conceivably the output of this utility might be included in one of the ChromeOS :/system sections, so it was attempted to write this procedure 'fail safe', namely reporting errors and not continuing processing if something goes wrong. Including of coreboot/src .h files will allow to keep the firmware timestamp implementation and this utility in sync in the future. Test: . build the utility (run 'make' while in chroot in util/cbmem) . copy `cbmem' and 'cbmem.py' to the target . run both utilities (limiting cbmem.py output to 25 lines or so) . observe that the generated tables are identical (modulo rounding up of int division, resulting in 1 ns discrepancies in some cases) localhost var # ./cbmem 18 entries total: 1:62,080 2:64,569 (2,489) 3:82,520 (17,951) 4:82,695 (174) 8:84,384 (1,688) 9:131,731 (47,347) 10:131,821 (89) 30:131,849 (27) 40:132,618 (769) 50:134,594 (1,975) 60:134,729 (134) 70:363,440 (228,710) 75:363,453 (13) 80:368,165 (4,711) 90:370,018 (1,852) 99:488,217 (118,199) 1000:491,324 (3,107) 1100:760,475 (269,150) localhost var # ./cbmem.py | head -25 time base 4249800, total entries 18 1:62,080 2:64,569 (2,489) 3:82,520 (17,951) 4:82,695 (174) 8:84,384 (1,688) 9:131,731 (47,347) 10:131,821 (89) 30:131,849 (27) 40:132,618 (769) 50:134,594 (1,975) 60:134,729 (134) 70:363,440 (228,710) 75:363,453 (13) 80:368,165 (4,711) 90:370,018 (1,852) 99:488,217 (118,199) 1000:491,324 (3,107) 1100:760,475 (269,150) Change-Id: I013e594d4afe323106d88e7938dd40b17760621c Signed-off-by: Vadim Bendebury <vbendeb@chromium.org> Reviewed-on: http://review.coreboot.org/1759 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>

Utility to dump boot timing table Coreboot and u-boot create a table of timestamps which allows to see the boot process performance. The util/cbmem/cbmem.py script allows to access the table after ChromeOS boots up and display its contents on the console. The problem is that shipping images do not include Python interpreter, so there is no way to access the table on a production machine. This change introduces a utility which is a Linux app displaying the timestamp table. Conceivably the output of this utility might be included in one of the ChromeOS :/system sections, so it was attempted to write this procedure 'fail safe', namely reporting errors and not continuing processing if something goes wrong. Including of coreboot/src .h files will allow to keep the firmware timestamp implementation and this utility in sync in the future. Test: . build the utility (run 'make' while in chroot in util/cbmem) . copy `cbmem' and 'cbmem.py' to the target . run both utilities (limiting cbmem.py output to 25 lines or so) . observe that the generated tables are identical (modulo rounding up of int division, resulting in 1 ns discrepancies in some cases) localhost var # ./cbmem 18 entries total: 1:62,080 2:64,569 (2,489) 3:82,520 (17,951) 4:82,695 (174) 8:84,384 (1,688) 9:131,731 (47,347) 10:131,821 (89) 30:131,849 (27) 40:132,618 (769) 50:134,594 (1,975) 60:134,729 (134) 70:363,440 (228,710) 75:363,453 (13) 80:368,165 (4,711) 90:370,018 (1,852) 99:488,217 (118,199) 1000:491,324 (3,107) 1100:760,475 (269,150) localhost var # ./cbmem.py | head -25 time base 4249800, total entries 18 1:62,080 2:64,569 (2,489) 3:82,520 (17,951) 4:82,695 (174) 8:84,384 (1,688) 9:131,731 (47,347) 10:131,821 (89) 30:131,849 (27) 40:132,618 (769) 50:134,594 (1,975) 60:134,729 (134) 70:363,440 (228,710) 75:363,453 (13) 80:368,165 (4,711) 90:370,018 (1,852) 99:488,217 (118,199) 1000:491,324 (3,107) 1100:760,475 (269,150) Change-Id: I013e594d4afe323106d88e7938dd40b17760621c Signed-off-by: Vadim Bendebury <vbendeb@chromium.org> Reviewed-on: http://review.coreboot.org/1759 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>

Utility to dump boot timing table Coreboot and u-boot create a table of timestamps which allows to see the boot process performance. The util/cbmem/cbmem.py script allows to access the table after ChromeOS boots up and display its contents on the console. The problem is that shipping images do not include Python interpreter, so there is no way to access the table on a production machine. This change introduces a utility which is a Linux app displaying the timestamp table. Conceivably the output of this utility might be included in one of the ChromeOS :/system sections, so it was attempted to write this procedure 'fail safe', namely reporting errors and not continuing processing if something goes wrong. Including of coreboot/src .h files will allow to keep the firmware timestamp implementation and this utility in sync in the future. Test: . build the utility (run 'make' while in chroot in util/cbmem) . copy `cbmem' and 'cbmem.py' to the target . run both utilities (limiting cbmem.py output to 25 lines or so) . observe that the generated tables are identical (modulo rounding up of int division, resulting in 1 ns discrepancies in some cases) localhost var # ./cbmem 18 entries total: 1:62,080 2:64,569 (2,489) 3:82,520 (17,951) 4:82,695 (174) 8:84,384 (1,688) 9:131,731 (47,347) 10:131,821 (89) 30:131,849 (27) 40:132,618 (769) 50:134,594 (1,975) 60:134,729 (134) 70:363,440 (228,710) 75:363,453 (13) 80:368,165 (4,711) 90:370,018 (1,852) 99:488,217 (118,199) 1000:491,324 (3,107) 1100:760,475 (269,150) localhost var # ./cbmem.py | head -25 time base 4249800, total entries 18 1:62,080 2:64,569 (2,489) 3:82,520 (17,951) 4:82,695 (174) 8:84,384 (1,688) 9:131,731 (47,347) 10:131,821 (89) 30:131,849 (27) 40:132,618 (769) 50:134,594 (1,975) 60:134,729 (134) 70:363,440 (228,710) 75:363,453 (13) 80:368,165 (4,711) 90:370,018 (1,852) 99:488,217 (118,199) 1000:491,324 (3,107) 1100:760,475 (269,150) Change-Id: I013e594d4afe323106d88e7938dd40b17760621c Signed-off-by: Vadim Bendebury <vbendeb@chromium.org> Reviewed-on: http://review.coreboot.org/1759 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>
