I'm sorry but a bug report like this isn't going to get looked at. |
|
@piotr-e: you just removed some AC97 stuff and hoped... it just works on the Pi? |

dmesg after mplayer running root@raspberrypi:/home/pi# |

For my SD card class 4(around 5MB/s) I see: For SD card class 10 (around 19-20MB/s) I see: Maybe is SD card bottleneck? |
|
I think the problem is we're not real time enough for high data rate isochronous USB transactions. |
|
I cannot run sdhci-bcm2708.sync_after_dma=0 in command line. |
|
Add it to /boot/cmdline.txt. |
|
I've done it but I don't notice any perceptible difference in the output for both SDs. |
|
@popcornmix, is it possible to fix this USB driver? Are you Raspberry Pi programmer? |
|
It is being worked on but it's not a simple fix #79. David |
|
Isochronous is now orders of magnitude more reliable with fiq_fsm. |
Currently it's assumed that firmware exports only the class of sensors supported by the driver. However with newer firmware or SCPI protocol revision, support for newer classes of sensors can be present. The driver fails to probe with the following warning if an unsupported class of sensor is encountered in the firmware. sysfs: cannot create duplicate filename '/devices/platform/scpi/scpi:sensors/hwmon/hwmon0/' ------------[ cut here ]------------ WARNING: at fs/sysfs/dir.c:31 Modules linked in: CPU: 0 PID: 6 Comm: kworker/u12:0 Not tainted 4.3.0-rc7 #137 Hardware name: ARM Juno development board (r0) (DT) Workqueue: deferwq deferred_probe_work_func PC is at sysfs_warn_dup+0x54/0x78 LR is at sysfs_warn_dup+0x54/0x78 This patch fixes the above issue by skipping through the unsupported class of SCPI sensors.

OMAP CPU hotplug uses cpu1's clocks and power domains for CPU1 wake up
from low power states (or turn on CPU1). This part of code is also
part of system suspend (disable_nonboot_cpus()).
>From other side, cpu1's clocks and power domains are used by CPUIdle. All above
functionality is mutually exclusive and, therefore, lockless clkdm/pwrdm api
can be used in omap4_boot_secondary().
This fixes below back-trace on -RT which is triggered by

We queue an irq work for deferred processing of mce event in realmode mce handler, where translation is disabled. Queuing of the work may result in accessing memory outside RMO region, such access needs the translation to be enabled for an LPAR running with hash mmu else the kernel crashes. After enabling translation in mce_handle_error() we used to leave it enabled to avoid crashing here, but now with the commit 74c3354 ("powerpc/pseries/mce: restore msr before returning from handler") we are restoring the MSR to disable translation. Hence to fix this enable the translation before queuing the work. Without this change following trace is seen on injecting SLB multihit in an LPAR running with hash mmu.

commit 4217d07 upstream. On Thundercomm TurboX CM2290, the eMMC OCR reports vdd = 23 (3.5 ~ 3.6 V), which is being treated as an invalid value by sdhci_set_power_noreg(). And thus eMMC is totally broken on the platform.
