net: New iface_stat module to monitor persistent network stats

2011-09-05T02:01:06+00:00

Adding a new module that tracks the number of bytes/packets transfered
by a network interface, even after the interface has been
removed. This is relevant to track the total data usage in mobile
devices whose interfaces are added and removed quite frequently (WiFi,
Bluetooth, 3G,..).

Monitoring is done only for devices that are configured with a valid
IP address (check to exclude virtual/loopback/tunnel interfaces).

net: activity_stats: Add statistics for network transmission activity

2011-09-05T01:57:43+00:00

When enabled, tracks the frequency of network transmissions
(inbound and outbound) and buckets them accordingly.
Buckets are determined by time between network activity.

Each bucket represents the number of network transmisions that were
N sec or longer apart. Where N is defined as 1 << bucket index.

This network pattern tracking is particularly useful for wireless
networks (ie: 3G) where batching network activity closely together
is more power efficient than far apart.

New file: /proc/net/stat/activity

output:

Min Bucket(sec) Count
              1 7
              2 0
              4 1
              8 0
             16 0
             32 2
             64 1
            128 0

ENGR00133690 Android pmem: fix bug of first open check to pmem device

2011-02-12T07:57:55+00:00

Due to the change: d405640539555b601e52f7d18f1f0b1345d18bf5,
the file->private_data is no longer initialized to NULL.
But assigned to miscdevice structure.

ENGR00133687 Android pmem: change the noncached buffer prot to writecombine.

2011-02-12T07:57:45+00:00

Workaround for imx5x M4IF burst len errata when armv7 neon enabled:
if the burst len > 8bytes, access the strongly ordered memory,
the result is not correct.
Use pgprot_writecombine to map the memory to uncached and normal memory type,
instead of pgprot_noncached which maps to strongly ordered memory,
to avoid burst len > 8.

pmem: add google's process memory allocator driver for Android

2011-02-12T07:47:01+00:00

The pmem driver is used to manage large (1-16+MB) physically contiguous
regions of memory shared between userspace and kernel drivers (dsp, gpu,
etc).

ENGR00137979-3 add performance monitor driver

2011-02-03T22:43:57+00:00

	add performance monitor driver.
	sample:
		cd /sys/devices/platform/mxs-perfmon.0/
   		'echo 1 > MIDn-xxx' to enable monitor this channel
			n: channel number; xxx: name of channel (PXP, LCD...)
			you can enable the multiple channels you want to
			monitor respectively using this command.
			use following command to check the channel is enabled
		'cat MIDn-xxx'
			1: enable; 0: disable

		'echo read > Monitor' to monitor all read activities
		'echo start > Monitor' to start monitoring
		'echo fetch > Monitor' to get a snapshot of monitor statistics.
		'cat xxx_Count' to show the statistics.
			xxx: name of statistics, (Data, Transfer, Latency...)

		'echo clear > Monitor' to clear snapshot of monitor statistics.
		'echo stop > Monitor' to stop monitoring
