flashrom on an Alpha Workstation 433au
by adrian.glaubitz＠googlemail.com 03 Apr '10

03 Apr '10

Hi, as the subject suggests I have run flashrom on a DEC Alpha Digital Personal Workstation [1], model 433au. flashrom itself segfaults but superiotool finds a SuperIO at least. Most DEC Alpha workstations are flashed using a proprietary flash utility which is run from the the SRM console [2]. There are several manuals on the net from DEC and Compaq which describe how to update the firmware using the original utilities, for example [3]. I have no idea so far how to enable/disable writing to the flash rom chips but I think it should not require any more magic than on x86 systems ;). Especially, because many of the Alpha systems are actually using Intel chipsets. Usually those Alpha machines have a jumper onboard which enables/disables flash write so there probably isn't the need for a specific board enable at all. Probably it's just a matter of finding the proper location of the address space of the flash chip in memory. I'm attaching the debug logs for superiotool -dV, lspci -nnvvvxxx and flashrom -V.

I'm pretty sure that FEATURE_ADDR_SHIFTED has another meaning (the 0x555 etc shifted left by one bit). The id2_offset may be needed anyway, but I propose to use a variable "shifted" which is 0 for all non-shifted chips and 1 for all shifted chips. It would be used as left shift for every programmatic access to special addresses. Such a change would allow us to kill m29f400bt.c which has buggy write functions anyway. Example for probing: /* Issue JEDEC Product ID Entry command */ chip_writeb(0xAA, bios + (0x5555 & mask) << shifted); chip_writeb(0x55, bios + (0x2AAA & mask) << shifted); chip_writeb(0x90, bios + (0x5555 & mask) << shifted); > + id2_offset = 2; > + else > + id2_offset = 1; > > /* Reset to get a clean state */ > chip_writeb(0xFF, bios); > @@ -58,7 +64,7 @@ int probe_82802ab(struct flashchip *flash) > programmer_delay(10); > > id1 = chip_readb(bios); > Arguably my "shifted" proposal suggests to use the following line for consistency: id1 = chip_readb(bios + 0x00 << shifted); > - id2 = chip_readb(bios + 0x01); > + id2 = chip_readb(bios + id2_offset); > id2 = chip_readb(bios + 0x01 << shifted); > > /* Leave ID mode */ > chip_writeb(0xFF, bios); > @@ -72,7 +78,7 @@ int probe_82802ab(struct flashchip *flash) > > /* Read the product ID location again.

It is essentially special-casing partial writes for a family of chips instead of doing it correctly in the generic code. The conversion to partial writes will happen post 0.9.2 anyway, and then this code will be ripped out completely. Your changes, on the other hand, beat at least some sanity into the code, so it would be desirable to have them in generic code post-0.9.2.

Suggestions: How about pointing the FEATURE_ADDR_SHIFTED chips to a to-be-fixed m29f400bt.c for now? It would reduce jedec.c changes a bit. How about using erase_flash() in write_82802ab() and dropping any rolling reflash mechanism until post 0.9.2? It should solve all non-uniform sector stuff. While that's a fear-reaching change as well, I believe it makes the code more reviewable, and does allow us to kill more duplicated code. As an added benefit, conversion to partial write will be easier. Regards, Carl-Daniel -- http://www.hailfinger.org/

Hardware Sequencing vs Software Sequencing
by john warwick 01 Apr '10

01 Apr '10

Hi, I was looking through the code, and see that flashrom is using software sequencing. Is there any reason for software sequencing to be chosen instead of hardware sequencing? Are there any restrictions imposed for hardware sequencing?

[PATCH] Fix the delay loop
by Carl-Daniel Hailfinger 01 Apr '10

01 Apr '10

[Side note: This is not the big timing code rewrite I originally wanted to post. I decided to focus on readable code instead of clever code. My other rewrite is available on request if anyone is interested.] The current delay loop calculation is still from revision 1 of flashrom, and since then it had a logic bug which caused all delays to be twice as long as intended. Fix the delay duration. Protect against delay loop overflows. Detect a non-working delay loop. Change the delay loop itself to ensure clever compiler optimizers won't eliminate it (as happens with clang/llvm in the current code). Some people suggested machine-specific asm, but the empty asm statement with the loop counter as register/memory input has the benefit of being perfectly cross-platform and working in gcc and clang. If time goes backwards (catastrophical NTP time difference, manual time change), timing measurements were shot because the new-old time subtraction yielded negative numbers which weren't handled correctly because the variable is unsigned. Simply return 1 microsecond timing in that case. If time goes forward too fast, pick the biggest possible timing measurement with a guaranteed overflow avoidance for all timing calculations. Check four times if the calculated timing is at most 10% too fast. This addresses OS scheduler interactions, e.g. being scheduled out during measurement which inflates measurements. If the timing is off, recalculate the timer values up to four times before giving up. Avoid division by zero in rare cases where timing measurements for a 250 ms delay return 0 us elapsed.

Change the delay loop itself to ensure clever compiler optimizers won't eliminate it (as happens with clang/llvm in the current code). Some people suggested machine-specific asm, but the empty asm statement with the loop counter as register/memory input has the benefit of being perfectly cross-platform and working in gcc and clang. If time goes backwards (catastrophical NTP time difference, manual time change), timing measurements were shot because the new-old time subtraction yielded negative numbers which weren't handled correctly because the variable is unsigned. Work around that issue (a fix is mathematically impossible). If time goes forward too fast, pick the biggest possible timing measurement with a guaranteed overflow avoidance for all timing calculations. Check four times if the calculated timing is at most 10% too fast. This addresses OS scheduler interactions, e.g. being scheduled out during measurement which inflates measurements. If the timing looks like garbage, recalculate the timer values up to four times before giving up. Avoid division by zero in rare cases where timing measurements for a 250 ms delay returned 0 us elapsed.

SST 49LF0008A - Erase problem (and solution)
by Panino ColSalame 29 Mar '10

29 Mar '10

Hello, I'm playing with flashrom on an ASEM Industrial PC based on an Atom Z530 and the US15W (Poulsbo) System Controller Hub. The BIOS flash is the SST 49LF0008A (Firmware Hub). After downloading the latest development code using git, flashrom was able to detect and read the flash, but the erase command failed. At first I've tried to increase the delay that is used by the toggle functions in jedec.c, passing from the default 8 to 80 (just for testing). At this point, the Erase command started to work properly. SST manual reads: The End-of-Write detection mode is incorporated into the FWH Read cycle. The actual completion of the nonvolatile write is asynchronous with the system; therefore, either a Data# Polling or Toggle Bit read may be simultaneous with the completion of the Write cycle. If this occurs, the system may possibly get an erroneous result, i.e., valid data may appear to conflict with either DQ7 or DQ6. In order to prevent spurious rejection, if an erroneous result occurs, the software routine should include a loop to read the accessed location an additional two (2) times. If both reads are valid, then the device has completed the Write cycle, otherwise the rejection is valid. So, I've set the delay for reading the toggle bit again to the default value of 8 and I've added an additional toggle bit check, in case the first one seems to be ok. It works! So, I'm able to Read, Write and Erase the chip.

[PATCH] Support for PCM Pm39LV020 and Pm39LV040
by Anders Juel Jensen 28 Mar '10

28 Mar '10

According to the data sheet these are identical to the 39LV010 in every respect except capacity. Unfortunately I can't test this, as I am on a laptop. Flashrom simply doesn't detect the chip. Signed-of-by: Anders Juel Jensen <andersjjensen(a)gmail.com>

Unused functions...
by Carl-Daniel Hailfinger 27 Mar '10

27 Mar '10

We have a few unused functions in our codebase. Should we - mark then static (may cause gcc to complain if -Wunused-function is enabled) - put them inside #if 0 (code will bitrot) - remove them from the source base entirely (some may be used in the future) jedec.c: data_polling_jedec (maybe some chip in the future won't support toggle_jedec) stm50flw0x0x.c: erase_sector_stm50flw0x0x (keep?) m29f400bt.c: write_m29f400bt (hm, probably kill) 82802ab.c: erase_82802ab (kill, old-style erase) pm49fl00x.c: lock_49fl00x (for the future) sst49lfxxxc.c: unlock_block_49lfxxxc (strange, don't we use that?) spi.c: default_spi_send_command (if one chip driver ever supports only multicommand) spi25.c: spi_write_status_enable (we should use it, some chips require that) spi_write_disable (does that make sense?) spi_aai_write (need some write infrastructure changes for this) spi_chip_erase_d8 (kill) flashrom.c: chip_writel (will we ever need it?) chip_writen (this one might be usable for a few chip drivers) chip_readl (will we ever need it?) list_programmers (no idea) register_shutdown (needed for ECs) need_erase (needed for partial write) internal.c: pci_dev_find_filter (hmmm) Regards, Carl-Daniel -- http://www.hailfinger.org/
