libata: blacklist Micron 500IT SSD with MU01 firmware

2018-05-30T05:48:51+00:00

commit 136d769e0b3475d71350aa3648a116a6ee7a8f6c upstream.

While whitelisting Micron M500DC drives, the tweaked blacklist entry
enabled queued TRIM from M500IT variants also. But these do not support
queued TRIM. And while using those SSDs with the latest kernel we have
seen errors and even the partition table getting corrupted.

Some part from the dmesg:

After few reboots with these errors, and the SSD is corrupted.
After blacklisting it, the errors are not seen and the SSD does not get
corrupted any more.

Sandisk SSDs SD7SN6S256G and SD8SN8U256G are regularly locking up

libata: Apply NOLPM quirk for SanDisk SD7UB3Q*G1001 SSDs

2018-05-16T08:06:51+00:00

commit 184add2ca23ce5edcac0ab9c3b9be13f91e7b567 upstream.

Richard Jones has reported that using med_power_with_dipm on a T450s
with a Sandisk SD7UB3Q256G1001 SSD (firmware version X2180501) is
causing the machine to hang.

Switching the LPM to max_performance fixes this, so it seems that
this Sandisk SSD does not handle LPM well.

Note in the past there have been bug-reports about the following
Sandisk models not working with min_power, so we may need to extend
the quirk list in the future: name - firmware
Sandisk SD6SB2M512G1022I   - X210400
Sandisk SD6PP4M-256G-1006  - A200906

ata: libahci: properly propagate return value of platform_get_irq()

2018-04-13T17:50:06+00:00

[ Upstream commit c034640a32f8456018d9c8c83799ead683046b95 ]

When platform_get_irq() fails, it returns an error code, which
libahci_platform and replaces it by -EINVAL. This commit fixes that by
propagating the error code. It fixes the situation where
platform_get_irq() returns -EPROBE_DEFER because the interrupt
controller is not available yet, and generally looks like the right
thing to do.

We pay attention to not show the "no irq" message when we are in an
EPROBE_DEFER situation, because the driver probing will be retried
later on, once the interrupt controller becomes available to provide
the interrupt.

libata: Modify quirks for MX100 to limit NCQ_TRIM quirk to MU01 version

2018-03-28T16:40:14+00:00

commit d418ff56b8f2d2b296daafa8da151fe27689b757 upstream.

When commit 9c7be59fc519af ("libata: Apply NOLPM quirk to Crucial MX100
512GB SSDs") was added it inherited the ATA_HORKAGE_NO_NCQ_TRIM quirk
from the existing "Crucial_CT*MX100*" entry, but that entry sets model_rev
to "MU01", where as the entry adding the NOLPM quirk sets it to NULL.

This means that after this commit we no apply the NO_NCQ_TRIM quirk to
all "Crucial_CT512MX100*" SSDs even if they have the fixed "MU02"
firmware. This commit splits the "Crucial_CT512MX100*" quirk into 2
quirks, one for the "MU01" firmware and one for all other firmware
versions, so that we once again only apply the NO_NCQ_TRIM quirk to the
"MU01" firmware version.

libata: Make Crucial BX100 500GB LPM quirk apply to all firmware versions

2018-03-28T16:40:14+00:00

commit 3bf7b5d6d017c27e0d3b160aafb35a8e7cfeda1f upstream.

Commit b17e5729a630 ("libata: disable LPM for Crucial BX100 SSD 500GB
drive"), introduced a ATA_HORKAGE_NOLPM quirk for Crucial BX100 500GB SSDs
but limited this to the MU02 firmware version, according to:
http://www.crucial.com/usa/en/support-ssd-firmware

MU02 is the last version, so there are no newer possibly fixed versions
and if the MU02 version has broken LPM then the MU01 almost certainly
also has broken LPM, so this commit changes the quirk to apply to all
firmware versions.

libata: Apply NOLPM quirk to Crucial M500 480 and 960GB SSDs

2018-03-28T16:40:14+00:00

commit 62ac3f7305470e3f52f159de448bc1a771717e88 upstream.

There have been reports of the Crucial M500 480GB model not working
with LPM set to min_power / med_power_with_dipm level.

It has not been tested with medium_power, but that typically has no
measurable power-savings.

Note the reporters Crucial_CT480M500SSD3 has a firmware version of MU03
and there is a MU05 update available, but that update does not mention any
LPM fixes in its changelog, so the quirk matches all firmware versions.

In my experience the LPM problems with (older) Crucial SSDs seem to be
limited to higher capacity versions of the SSDs (different firmware?),
so this commit adds a NOLPM quirk for the 480 and 960GB versions of the
M500, to avoid LPM causing issues with these SSDs.

libata: disable LPM for Crucial BX100 SSD 500GB drive

commit b17e5729a630d8326a48ec34ef02e6b4464a6aef upstream.

After Laptop Mode Tools starts to use min_power for LPM, a user found
out Crucial BX100 SSD can't get mounted.

Crucial BX100 SSD 500GB drive don't work well with min_power. This also
happens to med_power_with_dipm.

So let's disable LPM for Crucial BX100 SSD 500GB drive.

libata: Apply NOLPM quirk to Crucial MX100 512GB SSDs

2018-03-28T16:40:14+00:00

commit 9c7be59fc519af9081c46c48f06f2b8fadf55ad8 upstream.

Various people have reported the Crucial MX100 512GB model not working
with LPM set to min_power. I've now received a report that it also does
not work with the new med_power_with_dipm level.

It does work with medium_power, but that has no measurable power-savings
and given the amount of people being bitten by the other levels not
working, this commit just disables LPM altogether.

Note all reporters of this have either the 512GB model (max capacity), or
are not specifying their SSD's size. So for now this quirk assumes this is
a problem with the 512GB model only.
