Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.

Provide a multiplatform kernel for ast & qemu
Would be nice to use a single build & source tree for hardware and qemu.
If we don't have a suitable qemu model available, a single source tree (but separate build) would be ok.

Fix might be as simple as:
spin_lock(&ndp->ndp_package_lock); -> spin_lock_irqsave(...);
list_for_each_entry_safe(np, tmp, &ndp->ndp_packages, np_node)
ncsi_release_package(np);
spin_unlock(&ndp->ndp_package_lock); -> spin_lock_irqrestore(...);
but I'll check with Gavin.
Add CI for kernel tree
Now that we have a Qemu model of the ast2400 and ast2500 we should do builds and boot test on openpower.xyz
ftgmac is still not detecting link if cable plugged in after BMC is booted
Here are steps to fail:
- LAN cable plugged
- BMC booted
- Setup network
[network works fine] - turn off AC
- unplug LAN cable
- turn on AC
- BMC boots
- Plug in cable
- LAN is not enabled (ftgmac100: NCSI dev is down)

pr_warn from fs/jffs2/scan.c line 671 in new 4.4 kernel
The jffs2 file system over the ast2400 fmc driver is working fine on the dev-4.3 branch 35d2cfb . But the file system is spewing pr_warn in the dev-4.4 branch 1500e26 .
The spew is from fs/jffs2/scan.c line 671. The whole scan.c file has not changed between revisions. A quick web search shows this is likely due to either file system corruption or a bad driver. After scanning file system for tens of minutes the file system typically reports an error. Returning to a previous 4.3 kernel build the flash is able to be read.
The error could be caused by flash partition alignment, by flash driver, or by something elsewhere in the kernel.
I did a very quick web search and found plenty of hits the first few I looked at were recovered with erasing and formating the whole partition. I did a git diff on the file and there have been zero changes since Febuary 2012 in kernel v3.4-rc1. I did a git diff between drivers/mtd/spi-nor/ and see changes including moving the struct mtd around, but no obvious errors on first scan.
It has been suggested a bisect be attempted, but that will require cherry picking each aspeed support patch stack for each rev (outside the add support options). I feel an attempt to recreate on an existing mtd platform in qemu or similar be attempted first, and/or logging the IO to the flash to compare the pattern.
device tree support for adm1278
Following from the discussion in openbmc/openbmc#212 (comment), we need extra features not present in the upstream driver:
- device tree probing shenki@5fbf374
- support sense resistor shenki@dd13a2c
- add to Barreleye device tree shenki@f24385a
@adamliyi can you please review these changes for me, and if you are happy with them, I will add them to our kernel tree

Firestone PHY only works in mode 100base-T
The Firestone openpower board has a BCM54210E, but it doesn't work in 1000base-T.
Gavin worked around this by changing the PHY driver to only advertise 100Mbit:
diff --git a/drivers/net/phy/broadcom.c b/drivers/net/phy/broadcom.c
index 3743164..95208b0 100644
--- a/drivers/net/phy/broadcom.c
+++ b/drivers/net/phy/broadcom.c

.phy_id = PHY_ID_BCM54210E,
.phy_id_mask = 0xfffffff0,

We need to work out what is going on. Ben said:
The MAC in the ast2400 is a gigabit MAC. So it should all work normally
at 1000bT. If not, then something is wrong that needs to be
investigated:- Either the interface between MAC and PHY isn't wiredcorrectly (RGMII vs. RMII, RGMII uses more pins and a diff. clock)
- Or we don't set a setting or strap somewhere to switchbetween those modes (hardware strapping bit[7:6], SCU[A0], ...)
- Both ?If we are indeed limited to 100bT, then we should expose that one way
or another in the device-tree in order to limit the advertized speed in
the PHY driver.
Our Firestone machines are pre-production hardware.
i2c errors on ast2500 platform
At boot, the first i2c bus that is active will print this forever:
i2c_aspeed i2c-3: Invalid state (msg (null), pending 0)?
i2c_aspeed i2c-3: Invalid state (msg (null), pending 0)?
CONFIG_NET_NSCI=n and having ncsi in device tree breaks sliently
We should warn when this happens, and/or not enable NSCI. Currently it fails silently.
Kernel crash caused by network setting.
Reproduce step:
1. Do not plug in LAN cable
2. AC on
3. Log in BMC
4. plug in LAN cable
5. Set ifconfig IP
6. ifconfig eth0 down
7. ifconfig eth0 up
8. kernel crash

aspeed-smc driver support for AST2500 SPI flash controller
We need to support the register layout for the AST2500 SPI flash controller, selected by compatible = "aspeed,ast2500-smc";
MTD driver to host PNOR issue
I've been testing out the MTD driver.
Minimal testing has uncovered an issue in that reading from /dev/mtd7 (the host PNOR) is unreliable.
$ dd if=/dev/mtd7 of=/tmp/pnor count=1
Appears to work, what looks like an FFS header is in /tmp/pnor. Repeating that command reads all FF.
Didn't reproduce on /dev/mtd0.
NCSI not working on ast2500
Running dev-4.7 with @amboar's ftgmac100 fixes on an ast2500 platform with NCSI, we boot and bring up the device:

reboot issues on palmetto with non-openbmc userspace
I am booting dev-4.3 and dev-4.4 on a palmetto using a simple buildroot userspace. I do not see any output on the serial console after rebooting. Using an openbmc userspace this works fine.
The differences in the SCU and SMC (flash) registers are:
| Name | Address | openbmc | buildroot |
|---|---|---|---|
| System Reset Control/Status | 0x1e6e203c |
0x00000001 |

tmp423 probe is failing
On palmetto, the tmp423 that is in device tree is not being instantiated:
[ 67.340000] tmp421 2-004c: Could not read configuration register (-5)
[ 67.350000] tmp421: probe of 2-004c failed with error -5
but, I can read the mfg and device id reg manually and they look ok:
root@palmetto:~# i2cget 2 0x4c 0xff b
WARNING! This program can confuse your I2C bus, cause data loss and worse!
I will read from device file /dev/i2c-2, chip address 0x4c, data address
0xff, using read byte data.
Continue? [Y/n]
0x23
I also tried to manually instantiate the occ driver, and it gives an error too on Palmetto only. Barreleye is fine. the lm75 works fine on Barreleye.
LED sub-node property "default-state" is not working
Currently the beep LED turns to OFF during kernel loading.
I tried to keep beep LED as solid ON and plan to turn it off by skeleton service once it is available.
Depend on the LED sub-node properties descriptions, it can be accomplished by default-state = "on", but it is not working. The LED will be turned to OFF during create_gpio_led function.
Here are my rough debug and seems that the value didn't be success write into the gpio.
Sorry that I have no idea how trace chip->direction_output for further debug.
Is there any known issue or fix from new kernel regarding to the gpiod_direction_output function?

kernel unable to access tmp421 and ds1307
@bradbishop commented on Wed Jun 29 2016
Similar to openbmc/u-boot#11, this seems to be a hangup for the kernel due to the move from 2013.07 to 2016.05.
On bmc boot the rtc and tmp421 sensor cannot be accessed:
rtc-ds1307: probe of 0-0068 failed with error -5
tmp421 2-004c: Could not read configuration register (-5)
tmp421: probe of 2-004c failed with error -5
@shenki commented on Thu Jun 30 2016
Thanks for testing. I assume this is on Palmetto as well? Can you reproduce in Qemu?
We want these opened as kernel issues. We need the kernel handle poorly configured hardware.
@legoater commented on Thu Jun 30 2016
The previous u-boot was adding an I2C driver which was doing a reset of the I2C controller.
Should we add such a reset in the machine setup in the kernel ?
@williamspatrick commented on Thu Jul 14 2016
@shenki - Do you want this moved to kernel? You can move it with 'zenhub' (or I can do it for you).
@shenki commented on Tue Jul 19 2016
Yes, lets move this to the kernel

We could see kernel panic after AC cycle few times. Below is the BMC console information.
bmc_kernalpanic.txt
[Barreleye] ftgmac100 1e660000.ethernet eth0
@Kenthliu reported the following issue with tag openbmc tag v1.0:
Test AC cycle fails:
We found a lot of "kernel[]: ftgmac100 1e660000.ethernet eth0: rx crc err" and "kernel []: ftgmac100 1e660000.ethernet eth0: rx frame too long" messages in BMC console.
Here is the AC cycle step
- AC on
- BMC power on and enter to host
- There is a script in Ubuntu system. The script will send command to RMC via LAN.
- RMC make system AC off, then AC on.
We found the system stop at step 3.
At that situation, BMC is still alive, but showed many ftgmac error message.
So I suspect the LAN has some problems.

fib6_walk_continue: Unable to handle kernel paging request at virtual address 12005456
I've seen this panic with 6d93f62 a number of times under qemu's palmetto-bmc machine. Unsure at this stage whether it's the kernel or something qemu is doing wrong and I admit my qemu build is a bit of a mashup, but here's the panic output:

hwclock displaying error on empty date with kernel openbmc-20151210-1
When AC cycle is applied, the RTC date is empty (issue been tracked separately to find out why the RTC is not persisting the date).
With kernel 201521202, issuing "hwclock" from the BMC command line displays the epoch time.
After updating to kernel openbmc-20151210-1, hwclock displays an error:
root@barreleye:~# hwclock
hwclock: RTC_RD_TIME: Invalid argument
After updating the RTC via "hwclock -w", the "hwclock" command will display the date, so the issue is only when the RTC is empty.
openbmc/qemu does not support segment registers
I'm hitting a kernel panic when running the qemu palmetto-bmc machine.
I'm building qemu from the upstream openbmc/qemu tree, using steps described here.
$ git clone https://github.com/openbmc/qemu.git
$ cd qemu
$ git submodule update --init dtc
$ mkdir build
$ cd build
$ ../configure --target-list=arm-softmmu
$ make
Version looks correct for the newly built QEMU
ubuntu@mjturek-openbmc:~$ qemu/build/arm-softmmu/qemu-system-arm -version
QEMU emulator version 2.6.90 (v2.5.0-4924-g8b4e141-dirty), Copyright (c) 2003-2008 Fabrice Bellard
I build the image with the steps described here.
$ git clone https://github.com/openbmc/openbmc.git
$ cd openbmc
$ TEMPLATECONF=meta-openbmc-machines/meta-openpower/meta-ibm/meta-palmetto/conf . oe-init-build-env
$ bitbake obmc-phosphor-image
This creates the image openbmc/build/tmp/deploy/images/palmetto/flash-palmetto-<datetime>
Finally I run qemu as described here:
qemu-system-arm -m 256 -M palmetto-bmc -nographic \
-drive file=openbmc/build/tmp/deploy/images/palmetto/flash-palmetto-<datetime>,format=raw,if=mtd \
-net nic \
-net user,hostfwd=:127.0.0.1:2222-:22,hostfwd=:127.0.0.1:2443-:443,hostname=qemu \
Which eventually fails with this kernel panic

I've tried in both Ubuntu 14.04 and Ubuntu 16.04 with the same result.
As far as I can tell, I've followed the steps properly. Am I missing something or am I hitting a bug?
Investigate why we need CONFIG_SHMEM=y
@amboar wrote:
Subject: [PATCH] aspeed_defconfig: Enable SHMEM and TMPFS
Without enabling these options we get strange behaviour under qemu,
where it appears uevents aren't generated to create device nodes for
ttyS{0,4,5}. As a consequence we don't receive a getty on the console.C=C3=A9dric narrowed down the list of options initially at [1],
and with a patch to the qemu timer model[2] we can retain the
CONFIG_NO_HZ_IDLE=3Dy configuration.[1] openbmc/qemu#4
[2] https://lists.ozlabs.org/pipermail/openbmc/2016-May/003209.html
The CONFIG_SHMEM Kconfig has this to say:
CONFIG_SHMEM: โ
The shmem is an internal filesystem used to manage shared memory.
It is backed by swap and manages resource limits. It is also exported
to userspace as tmpfs if TMPFS is enabled. Disabling this
option replaces shmem and tmpfs with the much simpler ramfs code,
which may be appropriate on small systems without swap.
This suggests that when we disable SHMEM we should still be okay, and as we're a "small system without swap" this is an appropriate thing to disable. Perhaps there is some breakage upstream?

multi sector erase and write broken
When fw_setenv tries to erase the whole 128kB environment with one ioctl call the erase gails and the flash status register shows programming error status. Breaking the erase command into erase blocks should be handled by the spi-nor layer but is not working as of 4.3.
The busybox flash_cp command always uses one erase block per system call and is ok. The workaround is to copy the environment to ram in init and back if different at shutdown in the initramfs layer.
Note this also unifies /etc/fw_env.cfg at the cost of no redundant env support and lack of update on crash.
OCC driver is non-functional
Commit 087feba breaks the OCC hwmon driver. root@barreleye:/sys/bus/i2c/devices/3-0050# echo 1 > online
occ-i2c 3-0050: ERROR: no SENSOR String in response
occ-i2c 3-0050: ERROR: cannot get occ sensor data: -1
-sh: echo: write error: Operation not permitted
If I don't apply this commit, the driver works fine:
uname -r
4.3.4-fe68a785afbaa305506c87c6324f70ed0605385c
ls /sys/class/hwmon
hwmon0 hwmon1 hwmon2 hwmon3 hwmon4
Looks to me like line 582 in drivers/hwmon/power8_occ_i2c.c should not have been removed.
ncsi error on boot
@gwshan, I'm seeing this on boot with my 4.4 based aspeed tree:
ftgmac100: NCSI dev is down
I then did a ifconfig eth0 down and enabled debugging:
# echo "file net/ncsi/* +p" > control
# echo "file drivers/net/ethernet/faraday/ftgmac100.c +p" > control
# ifconfig eth0 up
Some time later (at least several seconds, perhaps a minute?) I got this:
ncsi_dev_start: Unrecognized NCSI dev state 0x304
ftgmac100: NCSI dev is up
And the interface was functional.

moxa_timer reload issue
I observe an issue in the moxart_clkevt_next_event. Right after the timer has been disabled, the new value for MATCH1 register calculated based up on the current COUNT register. Regarding to the datasheet, after the timer disabled then it's counter's register have to be reloaded with a RELOAD register value. But it seems it is not. Seems like SoC need some cycles to reload. We read current value near the same as MATCH1 (we stops counting a little later). So, each round of clockevent gets a lesser value of MATCH1 (interval grows dramatically). For example, if we did a double read from a COUNT register, everything seems ok. If we disable then enable and disable TIMER1 again it's make a trick too.
I suggest just set negated "cycles" value to the MATCH1 register. It is already known that the RELOAD value is all "ones" right after the one shot round.

adm1278 driver misses "in2_input" (Vout) sensor
There might be some issue with the upstream adm1278 hwmon driver. I haven't dig into the issue yet.
Some sensors are missing, e.g, "in2_input". This stands for "Vout" register in adm1278. Customer will need this sensor.
Here is the sensors currently available:

Bad page map after continue AC cycle
We use 0.6.1 stable pure code to run AC cycle by power cycle fixture.
This fixture can automatic AC on the system and then AC off after 3 minutes, and AC on again after 1 minutes.
Do this test continually and get the bad page map issue as attachment.
