libjpeg-turbo-1.1.1 + linaro Performance

by Tom Gall

Hi All, I've taken some time to freshen up the libjpeg-turbo hosted at lp:libjpeg-turbo to be refreshed with the upstream 1.1.1 plus Mandeeps previous work. I thought as part of this effort I'd do some performance comparisons between this new cut of code and the much older non arm optimized libjpeg62. For this test, I selected 3 ppms and 3 jpegs of the same image. The images are all color and are of the sizes : 1920x1024, 406x357 and 7227x3847. I placed the images inside of a ramdisk as well as would run the cjpeg and djpeg applications with time. Both cjpeg and djpeg and statically linked. I believe the libjpeg62 and libjpeg-turbo code using the current 4.5.2 version of gcc using the 0706 panda hwpack and LEB. Note, while these numbers are interesting to a point, time is I believe the wrong tool to make this measurement. Instead the call to the jpeg code should have time stamps before and after the operation to get a better idea of the time used. Numbers: cjpeg (ppm to jpeg conversion default parms) image size libjpeg62 libjpeg-turbo improvement (positive numbers are better) 1920x1024 real 0m0.522s real 0m0.452s +0.070s user 0m0.438s user 0m0.352s +0.086s sys 0m0.055s sys 0m0.070s -0.015s 406x357 real 0m0.086s real 0m0.085s +0.001s user 0m0.047s user 0m0.047s 0s sys 0m0.008s sys 0m0.008s 0s 7227x3847 real 0m3.812s real 0m4.075s - 0.263s user 0m3.461s user 0m3.711s - 0.250s sys 0m0.305s sys 0m0.328s - 0.023s djpeg (jpeg to ppm conversion default parms) image size libjpeg62 libjpeg-turbo improvement 1920x1024 real 0m0.414s real 0m0.294s +0.120s user 0m0.273s user 0m0.156s +0.117s sys 0m0.109s sys 0m0.109s 0s 406x357 real 0m0.079s real 0m0.072s +0.007s user 0m0.023s user 0m0.016s +0.007s sys 0m0.023s sys 0m0.023s 0s 7227x3847 real 0m7.517s real 0m10.099s -2.582s user 0m2.047s user 0m1.242s +0.805s sys 0m0.813s sys 0m0.859s -0.046s Further work: There are some additional patches from Michael Edwards, those were not part of this measurement tho I will be picking his patches up.

[uboot PATCH] Add uboot "fdt_high" enviroment variable

by David A. Long

From: David A. Long <dave.long(a)linaro.org> Add a new "fdt_high" enviroment variable. This can be used to control (or prevent) the relocation of the flattened device tree on boot. It can be used to prevent relocation of the fdt into highmem. The variable behaves similarly to the existing "initrd_high" variable. Signed-off-by: David A.

[ACTIVITY] Multimedia WG status report - wk27.2011 (20110704-20110708)

by Ilias Biris

Last meeting minutes: https://wiki.linaro.org/WorkingGroups/Middleware/Multimedia/Notes/2011-07-05 Current status report:https://wiki.linaro.org/WorkingGroups/Middleware/Multimedia/WeeklyRe… Highlights: Issues/Changes: Mandeep Kumar is not contributing to Linaro work. A suitable replacement is sought after with the member company. As a plan-B Ilias has asked another member of the team to look after JPEG-turbo for 1107 release, providing the release and any necessary highlights to release management. This plan should be confirmed with Kurt once he is back from vac. Info has already been shared with the team member picking up jpeg-turbo As a result of this change sending the public plan review presentation to the TSC was postponed till Kurt has a new version of the plan. Public plan review: this is still planned to take place on 13 or 14 of July. Final date will be determined next week. The blueprints for the work now look to be mostly in shape. Still to cover - Userspace UMM - robclark needs to clarify whether any userspace API related to buffer sharing needs a separate blueprint or it can be as a set of work items in the existing memory management blueprints. - Jpeg optimization related to codec optimization - due to the change mentioned above this will need to be revised to identify how to meet the 1107 and beyond targets - As a result of the change the team will doublecheck other blueprints for any timeline adjustments needed -- Ilias Biris ilias.biris(a)linaro.org Project Manager, Linaro M: +358504839608, IRC: ibiris Skype: ilias_biris Linaro.org│ Open source software for ARM SoCs

[ACTIVITY] Status report for Graphics WG - wk27.2011 (20110704-20110708)

by Ilias Biris

Status report is in https://wiki.linaro.org/WorkingGroups/Middleware/Graphics/WeeklyReport Last weekly meeting minutes can be found from https://wiki.linaro.org/WorkingGroups/Middleware/Graphics/Notes/2011-07-06 Highlights 11.06 release done, great thanks to all! Graphics deliverables were part of the release (glcompbench, glamrk2, unity, nux). Planning for 11.07 is now in place. Milestone pages created, blueprints associated, work now moving forward to meet the targets. See the planned release content from Graphics in https://wiki.linaro.org/Cycles/1107/Release/MilestonePagesStatus Preparation for Connect is ongoing. GLEW patches have been submitted upstream, discussing now the revisions to be made. Android targets: 0xbench - trying to see if the benchmarking work which Alexandros has been busy with can be folded into 0xbench. glmark2 seems to be a good candidate. ARMHF benchmarking for graphics was also discussed, if nothing else such work would provide also HF builds of the benchmarking packages we have in Graphics. Discussion ongoing, perhaps this is something to leave for discusion during Linaro Connect - it depends on the time available with the release happening in less than 2 weeks Memory management has seen a different kind of communication on the lists this week. Linaro folks are working to drive the solutions safely ahead, addressing stakeholder concerns on the way.

[ACTIVITY] Status report for Office of CTO - wk27.2011 (20110704-20110708)

by Ilias Biris

Status report: https://wiki.linaro.org/OfficeofCTO/WeeklyReport Weekly meeting minutes: https://wiki.linaro.org/OfficeofCTO/2011-07-05 Highlights: ARMHF: Konstantinos has been doing benchmarking (check out https://wiki.linaro.org/OfficeofCTO/HardFloat/Benchmarks for more details of the results so far). A first release of Konstantinos' own images will be made for the 1107 as a non-official use-at-own-risk set of images. Blueprint to follow the images release is https://blueprints.launchpad.net/linaro/+spec/engr-octo-armhf-images. ArmHF Cross bootstrap: just about getting in place. Working on a libtool bug, as well as a second issue which is a lot of perl modules which do not cross build Boot architecture meetings have started. Boot architecture seems to be on a good start, goal this week is to have an agenda for the face to face Linaro Connect meeting. Device tree: seems to be moving along well. Patches should if all goes as expected get merged in the 3.1 kernel window. Work is being done also on device model and how it relates to power management. Work for 1107 planned - related to Boot Architecture, final updates to the device tree documentation, ARMHF work, SMP (64 bit sync primitives in gcc). For the highlights only ARMHF images availability is provided now, depending how the rest of the work goes we may have additional highlights for documentation made available Finally, the Office of CTO wiki is being updated, so keep watching that space for better wiki pages that convey all the great work done by that team -- Ilias Biris ilias.biris(a)linaro.org Project Manager, Linaro M: +358504839608, IRC: ibiris Skype: ilias_biris Linaro.org│ Open source software for ARM SoCs
