A MMC card transfer issue

A MMC card transfer issue

[Tomoya MORINAGA]

I am facing the issue about some MMC cards on Intel EG20T PCH (Platform Controller Hub).
The linux version is 2.6.36.
I can not transfer data the MMC cards (e.g. Transcned MMC card).
The card is 1 bit bus width. And the card is according to MMC specification V3.x.
And the EG20T has a 4 bit bus width capability 
Linux MMC standard driver decides the card bus width as 4 bit,
if the MMC specification version is larger than or equal to V4.0 like below.

linux/drivers/mmc/core/mmc.c

 505        /*
 506         * Activate wide bus (if supported).
 507         */
 508        if ((card->csd.mmca_vsn >= CSD_SPEC_VER_4) &&
 509            (host->caps & (MMC_CAP_4_BIT_DATA | MMC_CAP_8_BIT_DATA))) {
 510                unsigned ext_csd_bit, bus_width;
 511
 512                if (host->caps & MMC_CAP_8_BIT_DATA) {
 513                        ext_csd_bit = EXT_CSD_BUS_WIDTH_8;
 514                        bus_width = MMC_BUS_WIDTH_8;
 515                } else {
 516                        ext_csd_bit = EXT_CSD_BUS_WIDTH_4;
 517                        bus_width = MMC_BUS_WIDTH_4;
 518                }
 519
 520                err = mmc_switch(card, EXT_CSD_CMD_SET_NORMAL,
 521                                 EXT_CSD_BUS_WIDTH, ext_csd_bit);
 522
 523                if (err && err != -EBADMSG)
 524                        goto free_card;
 525
 526                if (err) {
 527                        printk(KERN_WARNING "%s: switch to bus width %d "
 528                               "failed\n", mmc_hostname(card->host),
 529                               1 << bus_width);
 530                        err = 0;
 531                } else {
 532                        mmc_set_bus_width(card->host, bus_width);
 533                }
 534        }
 535

However the MMC specification version id is the same as V3.x and V4.0.
Therefore the driver uses the 4 bit bus width for the MMC card 
even if the card has only 1 bit bus width.
I modified the driver to use 1 bit bus width only tentatively and confirmed that
we can mount the card and R/W correctly.

I think we can not support MMC_CAP_4_BIT_DATA or MMC_CAP_8_BIT_DATA in MMC V4.0.

How do you think ?

You can find a patch for 4-bit support. the problem is there's some
bug related so it set the 4 & 8 bit support both.
So line 512 is always true. you can just remove the one line like this.

It's quirk-and-dirty patch. now we try to find a generic solution to
solve this issue.

Hi Park,

Thank you for your information.

Re: A MMC card transfer issue

Hi Park,

Though I  tried to patch yours to "sdhci.c" of linux-2.6.36,
but it seems your patch has already patched in linux-2.6.36.

Using this linux, MMC card is not recognized.
Inserting the MMC card, I saw the following erro message.

I have suspected mmc.c is buggy.
I tried to disable like the following in "mmc_init_card".
As a result, the MMC card to be recognized correctly.
What's do you think ?

Re: A MMC card transfer issue

[Philip Rakity]

I just looked in the 2.6.37 code and the fix is not there.  It is in the 2.6.37 linus  tree.  

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=drivers/mmc/core/mmc.c;h=16006ef153fe081c2f0f0a09cd4443ce7f3c49a1;hb=a25cecce88194b2edf38b8c3b1665e9318eb2d22

Chris Ball who maintains this should know when it will be pushed upwards.

Do you know when the above patch will be integrated to kernel ?

I don't understand, sorry.  The link is to a file, not a patch, and
Philip's statement above talks about a patch being in 2.6.37 but not
being in 2.6.37, which I don't understand either.

Looking back farther in the thread, I think you're both talking about:
http://git.kernel.org/?p=linux/kernel/git/cjb/mmc.git;a=commit;h=15ec44611904be0dcc97b84c29fbf964e5e2b36f

This patch was merged into Linus' 2.6.37-rc4 on Nov 27 2010, and
released as part of 2.6.37.

Can you elaborate on your question, if it's still outstanding?

Thanks,

Chris,

transcend card is 1 bit card.  Requires bus_width patches.

Re: A MMC card transfer issue

For 1 bit transcend cards you need these 2 patches.

Subject: [PATCH] mmc: Test bus-width for old MMC devices

Some old MMC devices fail with the 4/8 bits the driver tries to use
exclusively.  This patch adds a test for the given bus setup and falls
back to the lower bit mode (until 1-bit mode) when the test fails.

Subject: [PATCH] mmc: fix mmc_set_bus_width_ddr() call without bus-width-test cap

With the bus-width test patch, mmc_set_bus_width*() isn't called properly
when the driver doesn't set MMC_CAP_BUS_WIDTH and no DDR mode.
This patch fixes the regression by moving the call up before the cap test.

Hi Philip, Chris

> For 1 bit transcend cards you need these 2 patches.
Thank you for your information.
It seems these patches aren't applied for kernel-2.6.37, right ?

Will you apply these patches for kernel-2.6.38?

BTW, I attached dmesg log when inserts MMC card with kernel-2.6.37.

Thanks,

Re: A MMC card transfer issue

[Philip Rakity]

Did you define the CAP for BUS WIDTH ? 

MMC_CAP_BUS_WIDTH_TEST 

in the driver or the platform driver ?

Let me make the above meaning clear.

I don't modify kernel source code "drivers/mmc" at all
Is the above mean I must modify something kernel source code ?

yes

you need to have the driver or the low level code enable this QUIRK.

which mmc driver are you using.

Hi Philip,

Could you teach me how to get the information ?

BTW, Is the above permanent treatment?
I think modifying kernel source code isn't preferred.

Re: A MMC card transfer issue

[Philip Rakity]

There is no good answer.  

Doing this patch for 2.6.20 or so a long time ago had problems because some controllers did not work.  The failures were equally unpleasant.

The failure you see today is at least not a regression since 1 bit did not work before.  

We hope that developers who know their h/w works add the CAP.

RE: A MMC card transfer issue

[Tomoya MORINAGA]

Hi Philip,

> which MMC driver are you using.
According to boot message, it seems sdhci.c is loaded.

Do I add only  "mmc->caps |=  MMC_CAP_BUS_WIDTH_TEST" in sdhc.c ?

Thanks,
