[L] Change in flashrom[main]: Complete and fix progress feature implementation for all operations

Attention is currently required from: Aarya, Nikolai Artemiev, Sergii Dmytruk. Anastasia Klimchuk has posted comments on this change by Sergii Dmytruk. ( https://review.coreboot.org/c/flashrom/+/84102?usp=email ) Change subject: Complete and fix progress feature implementation for all operations ...................................................................... Patch Set 3: (1 comment) Patchset: PS1: > A comment to fix the tests I fixed the failing test, `spi_read_chunked_test_success` and also renamed it to `default_spi_read_test_success` because a higher level was needed to invoke progress Then, it turns out that `setup_progress_from_layout_and_diff` is causing tests in tests/chip.c to timeout. So I decided to split the commit and introduce `setup_progress_from_layout_and_diff` in the next commit (which is not ready yet because tests timeout). I think `setup_progress_from_layout` is already enough to display progress, it's not optimal but it works. It can be improved in the next commit. -- To view, visit https://review.coreboot.org/c/flashrom/+/84102?usp=email To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings?usp=email Gerrit-MessageType: comment Gerrit-Project: flashrom Gerrit-Branch: main Gerrit-Change-Id: If1e40fc97f443c4f0c0501cef11cff1f3f84c051 Gerrit-Change-Number: 84102 Gerrit-PatchSet: 3 Gerrit-Owner: Sergii Dmytruk <sergii.dmytruk(a)3mdeb.com> Gerrit-Reviewer: Aarya <aarya.chaumal(a)gmail.com> Gerrit-Reviewer: Anastasia Klimchuk <aklm(a)chromium.org> Gerrit-Reviewer: Nikolai Artemiev <nartemiev(a)google.com> Gerrit-Reviewer: Peter Marheine <pmarheine(a)chromium.org> Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-Attention: Aarya <aarya.chaumal(a)gmail.com> Gerrit-Attention: Nikolai Artemiev <nartemiev(a)google.com> Gerrit-Attention: Sergii Dmytruk <sergii.dmytruk(a)3mdeb.com> Gerrit-Comment-Date: Fri, 20 Sep 2024 13:59:24 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: Anastasia Klimchuk <aklm(a)chromium.org>

by Anastasia Klimchuk (Code Review) 20 Sep '24

20 Sep '24

Attention is currently required from: Aarya, Nikolai Artemiev, Sergii Dmytruk. Anastasia Klimchuk has uploaded a new patch set (#3) to the change originally created by Sergii Dmytruk. ( https://review.coreboot.org/c/flashrom/+/84102?usp=email ) The following approvals got outdated and were removed: Verified-1 by build bot (Jenkins) Change subject: Complete and fix progress feature implementation for all operations ...................................................................... Complete and fix progress feature implementation for all operations Original progress reporting implemented in CB:49643 and it has some issues, for example: size_t start_address = start; size_t end_address = len - start; End address is anything but length minus start address. update_progress(flash, FLASHROM_PROGRESS_READ, /*current*/ start - start_address + to_read, /*total*/ end_address); Total should just be length if that's how current value is computed. --- libflashrom needs to know total size ahead of time. That's init_progress() and changed update_progress(). It also needs to store the last current value to be able to update it. That's stage_progress in flashrom_flashctx. Measuring accurately amount of data which will be read/erased/written isn't easy because things can be skipped as optimizations. Current values are probably off, there are TODO/FIXME comments. --- CLI shares terminal with the rest of the code and has to maintain more state to handle that reasonably well. The progress doesn't just dump lots of stuff on the screen which probably won't fly because of CB:64668, but it's not hard to adjust this. --- A script to test the CLI: \#!/bin/bash t=${1:-rewW} shift if [[ $t =~ r ]]; then echo ">>> READ" ./flashrom -p dummy:emulate=W25Q128FV,freq=64mhz -r dump.rom --progress "$@" echo fi if [[ $t =~ e ]]; then echo ">>> ERASE" ./flashrom -p dummy:emulate=W25Q128FV,freq=64mhz -E --progress "$@" echo fi if [[ $t =~ w ]]; then echo ">>> WRITE (without erase)" dd if=/dev/zero of=zero.rom bs=1M count=16 2> /dev/null ./flashrom -p dummy:emulate=W25Q128FV,freq=64mhz -w zero.rom --progress "$@" echo fi if [[ $t =~ W ]]; then echo ">>> WRITE (with erase)" dd if=/dev/zero of=zero.rom bs=1M count=16 2> /dev/null dd if=/dev/random of=random.rom bs=1M count=16 2> /dev/null ./flashrom -p dummy:emulate=W25Q128FV,freq=64mhz,image=random.rom -w zero.rom --progress "$@" echo fi Co-developed-by: Anastasia Klimchuk <aklm(a)flashrom.org> Co-developed-by: Sergii Dmytruk <sergii.dmytruk(a)3mdeb.com> Change-Id: If1e40fc97f443c4f0c0501cef11cff1f3f84c051 Signed-off-by: Sergii Dmytruk <sergii.dmytruk(a)3mdeb.com> Signed-off-by: Anastasia Klimchuk <aklm(a)flashrom.org> --- M 82802ab.c M at45db.c M cli_classic.c M cli_output.c M dediprog.c M doc/release_notes/devel.rst M en29lv640b.c M erasure_layout.c M flashrom.c M include/flash.h M it87spi.c M jedec.c M libflashrom.c M linux_mtd.c M parade_lspcon.c M realtek_mst_i2c_spi.c M spi.c M spi25.c M sst28sf040.c M tests/chip.c M tests/spi25.c M tests/tests.c M tests/tests.h 23 files changed, 285 insertions(+), 50 deletions(-) git pull ssh://review.coreboot.org:29418/flashrom refs/changes/02/84102/3 -- To view, visit https://review.coreboot.org/c/flashrom/+/84102?usp=email To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings?usp=email Gerrit-MessageType: newpatchset Gerrit-Project: flashrom Gerrit-Branch: main Gerrit-Change-Id: If1e40fc97f443c4f0c0501cef11cff1f3f84c051 Gerrit-Change-Number: 84102 Gerrit-PatchSet: 3 Gerrit-Owner: Sergii Dmytruk <sergii.dmytruk(a)3mdeb.com> Gerrit-Reviewer: Aarya <aarya.chaumal(a)gmail.com> Gerrit-Reviewer: Anastasia Klimchuk <aklm(a)chromium.org> Gerrit-Reviewer: Nikolai Artemiev <nartemiev(a)google.com> Gerrit-Reviewer: Peter Marheine <pmarheine(a)chromium.org> Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-Attention: Aarya <aarya.chaumal(a)gmail.com> Gerrit-Attention: Nikolai Artemiev <nartemiev(a)google.com> Gerrit-Attention: Sergii Dmytruk <sergii.dmytruk(a)3mdeb.com>
