* | ALSA: hda-intel - remove model=hwio , use probe_only=3 insteadJaroslav Kysela2010-03-261-0/+3
| | | | | | | | | | | | | | | | The probe_only module parameter skips the codec initialization, too. Remove the model=hwio code and use second bit in probe_only to skip the HDA codec reset procedure. Signed-off-by: Jaroslav Kysela <perex@perex.cz>
* | ALSA: hda-intel - add special 'hwio' model to bypass initializationJaroslav Kysela2010-03-261-0/+5
|/ | | | | | | | | | Using the 'model=hwio' option, the driver bypasses any codec initialization and the reset procedure for codecs is also bypassed. This mode is usefull to enable direct access using hwdep interface (using hdaverb or hda-analyzer tools) and retain codec setup from BIOS. Signed-off-by: Jaroslav Kysela <perex@perex.cz>

This is necessary to move to the generic device model DMA API from the PCI bus specific API in the long term. dma_set_coherent_mask works in the exact same way that pci_set_consistent_dma_mask does. So this patch also changes pci_set_consistent_dma_mask to call dma_set_coherent_mask.

I made it clear that the sync_single API can do a partial sync but the sync_sg API can't. We could do a partial sync with the sync_sg API too, however, it's difficult for driver writers to correctly use the sync_sg API for a partial sync since the scatterlists passed in to the mapping API can't be modified. It's unlikely that driver writers want to do a partial sync with the sync_sg API (because the sync_sg API are usually used for block drivers). So I think that it's better to forbid a partial sync with the sync_sg API.

This adds a way to tune the CPU used by kipmid to help in those cases. By setting kipmid_max_busy_us to a value between 100 and 500, it is possible to bring down kipmid CPU load to practically 0 without loosing too much ipmi throughput performance. Not setting the value, or setting the value to zero, operation is unaffected.

Then, panic_on_oom=2 means painc_on_oom_always. Now, memcg doesn't check panic_on_oom flag. This patch adds a check. BTW, how it's useful ? kdump+panic_on_oom=2 is the last tool to investigate what happens in oom-ed system. When a task is killed, the sysytem recovers and there will be few hint to know what happnes. In mission critical system, oom should never happen. Then, panic_on_oom=2+kdump is useful to avoid next OOM by knowing precise information via snapshot. TODO: - For memcg, it's for isolate system's memory usage, oom-notiifer and freeze_at_oom (or rest_at_oom) should be implemented. Then, management daemon can do similar jobs (as kdump) or taking snapshot per cgroup.
