It is a bit odd that `get_next_write` returns len, but `need_erase` returns 0 or 1, it would be cool for it to return length as well. Similar to my other comment, I think that rounding up to granularity is the level of details which should be inside `need_erase`. However, what to do now. The granularity is default in all of the flashchips (except of just 3), and default is 256 bytes. The smallest eraseblock is 4K nowadays, which is way larger than 256 bytes. Maybe we can just leave it ? and move the fixme comment into need_erase? https://review.coreboot.org/c/flashrom/+/84439/comment/78f61d63_e0a4f19b?us… : PS13, Line 1281: // FIXME: should be rounded up to page size? It seems to me, this level of details is what `get_next_write` should be taking care of. And here, we should just take the len that get_next_write returns. However currently `get_next_write` ignores the page size, not sure if it's on purpose or todo left. I would leave the code here as is, and maybe move the fixme comment into get_next_write.

by Anastasia Klimchuk (Code Review) 19 Oct '24

19 Oct '24

Attention is currently required from: Aarya, Anastasia Klimchuk, Nikolai Artemiev. Anastasia Klimchuk has uploaded a new patch set (#11) 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 ( https://review.coreboot.org/c/flashrom/+/84102?usp=email ) The following approvals got outdated and were removed: Verified+1 by build bot (Jenkins) Change subject: Complete and fix progress feature implementation for all operations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. The next patch in the chain aims to address this, there are TODO/FIXME comments there. --- CLI shares terminal with the rest of the code and has to maintain more state to handle that reasonably well. Similar to CB:64668, an effort is made to keep the progress on a single line. Non-progress output is kept track of to know when moving to a new line cannot be avoided. --- 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, 325 insertions(+), 50 deletions(-) git pull ssh://review.coreboot.org:29418/flashrom refs/changes/02/84102/11 -- 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: 11 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: Anastasia Klimchuk <aklm(a)chromium.org> Gerrit-Attention: Nikolai Artemiev <nartemiev(a)google.com>
