- *
- *	Let's take these a step at a time
- *
- *	1. Allocated
- *		Pages allocated from the kernel may still have
- *		cache contents, so we set them to (CPU, CPU) always.
- *	2. Written by CPU (using pwrite)
- *		The pwrite function calls set_domain (CPU, CPU) and
- *		this function does nothing (as nothing changes)
- *	3. Mapped by GTT
- *		This function asserts that the object is not
- *		currently in any GPU-based read or write domains
- *	4. Read by GPU
- *		i915_gem_execbuffer calls set_domain (COMMAND, 0).
- *		As write_domain is zero, this function adds in the
- *		current read domains (CPU+COMMAND, 0).
- *		flush_domains is set to CPU.
- *		invalidate_domains is set to COMMAND
- *		clflush is run to get data out of the CPU caches
- *		then i915_dev_set_domain calls i915_gem_flush to
- *		emit an MI_FLUSH and drm_agp_chipset_flush
- *	5. Unmapped from GTT
- *		i915_gem_object_unbind calls set_domain (CPU, CPU)
- *		flush_domains and invalidate_domains end up both zero

+ * Set the next domain for the specified object. This
+ * may not actually perform the necessary flushing/invaliding though,
+ * as that may want to be batched with other set_domain operations
+ *
+ * This is (we hope) the only really tricky part of gem. The goal
+ * is fairly simple -- track which caches hold bits of the object
+ * and make sure they remain coherent. A few concrete examples may
+ * help to explain how it works. For shorthand, we use the notation
+ * (read_domains, write_domain), e.g. (CPU, CPU) to indicate the
+ * a pair of read and write domain masks.
+ *
+ * Case 1: the batch buffer
+ *
+ *	1. Allocated
+ *	2. Written by CPU
+ *	3. Mapped to GTT
+ *	4. Read by GPU
+ *	5. Unmapped from GTT
+ *	6. Freed
+ *
+ *	Let's take these a step at a time
+ *
+ *	1. Allocated
+ *		Pages allocated from the kernel may still have
+ *		cache contents, so we set them to (CPU, CPU) always.
+ *	2. Written by CPU (using pwrite)
+ *		The pwrite function calls set_domain (CPU, CPU) and
+ *		this function does nothing (as nothing changes)
+ *	3. Mapped by GTT
+ *		This function asserts that the object is not
+ *		currently in any GPU-based read or write domains
+ *	4. Read by GPU
+ *		i915_gem_execbuffer calls set_domain (COMMAND, 0).
+ *		As write_domain is zero, this function adds in the
+ *		current read domains (CPU+COMMAND, 0).
+ *		flush_domains is set to CPU.
+ *		invalidate_domains is set to COMMAND
+ *		clflush is run to get data out of the CPU caches
+ *		then i915_dev_set_domain calls i915_gem_flush to
+ *		emit an MI_FLUSH and drm_agp_chipset_flush
+ *	5. Unmapped from GTT
+ *		i915_gem_object_unbind calls set_domain (CPU, CPU)
+ *		flush_domains and invalidate_domains end up both zero
+ *		so no flushing/invalidating happens
+ *	6. Freed
+ *		yay, done
+ *
+ * Case 2: The shared render buffer
+ *
+ *	1. Allocated
+ *	2. Mapped to GTT
+ *	3. Read/written by GPU
+ *	4. set_domain to (CPU,CPU)
+ *	5. Read/written by CPU
+ *	6. Read/written by GPU
+ *
+ *	1. Allocated
+ *		Same as last example, (CPU, CPU)
+ *	2. Mapped to GTT
+ *		Nothing changes (assertions find that it is not in the GPU)
+ *	3. Read/written by GPU
+ *		execbuffer calls set_domain (RENDER, RENDER)
+ *		flush_domains gets CPU
+ *		invalidate_domains gets GPU
+ *		clflush (obj)
+ *		MI_FLUSH and drm_agp_chipset_flush
+ *	4. set_domain (CPU, CPU)
+ *		flush_domains gets GPU
+ *		invalidate_domains gets CPU
+ *		wait_rendering (obj) to make sure all drawing is complete.
+ *		This will include an MI_FLUSH to get the data from GPU
+ *		to memory
+ *		clflush (obj) to invalidate the CPU cache
+ *		Another MI_FLUSH in i915_gem_flush (eliminate this somehow?)
+ *	5. Read/written by CPU
+ *		cache lines are loaded and dirtied
+ *	6. Read written by GPU
+ *		Same as last GPU access
+ *
+ * Case 3: The constant buffer
+ *
+ *	1. Allocated
+ *	2. Written by CPU
+ *	3. Read by GPU
+ *	4. Updated (written) by CPU again
+ *	5. Read by GPU
+ *
+ *	1. Allocated
+ *		(CPU, CPU)
+ *	2. Written by CPU
+ *		(CPU, CPU)
+ *	3. Read by GPU
+ *		(CPU+RENDER, 0)
+ *		flush_domains = CPU
+ *		invalidate_domains = RENDER
+ *		clflush (obj)
+ *		MI_FLUSH
+ *		drm_agp_chipset_flush
+ *	4. Updated (written) by CPU again
+ *		(CPU, CPU)
+ *		flush_domains = 0 (no previous write domain)
+ *		invalidate_domains = 0 (no new read domains)
+ *	5. Read by GPU
+ *		(CPU+RENDER, 0)
+ *		flush_domains = CPU

+
+usRequestedPWMFreqInHz:           When it's set to 0x0 by SBIOS: the LCD BackLight is not controlled by GPU(SW). 
+                                  Any attempt to change BL using VBIOS function or enable VariBri from PP table is not effective since ATOM_BIOS_INFO_BL_CONTROLLED_BY_GPU==0;
+                                  
+                                  When it's set to a non-zero frequency, the BackLight is controlled by GPU (SW) in one of two ways below:
+                                  1. SW uses the GPU BL PWM output to control the BL, in chis case, this non-zero frequency determines what freq GPU should use;
+                                  VBIOS will set up proper PWM frequency and ATOM_BIOS_INFO_BL_CONTROLLED_BY_GPU==1,as the result,
+                                  Changing BL using VBIOS function is functional in both driver and non-driver present environment; 
+                                  and enabling VariBri under the driver environment from PP table is optional.
+
+                                  2. SW uses other means to control BL (like DPCD),this non-zero frequency serves as a flag only indicating
+                                  that BL control from GPU is expected.
+                                  VBIOS will NOT set up PWM frequency but make ATOM_BIOS_INFO_BL_CONTROLLED_BY_GPU==1
+                                  Changing BL using VBIOS function could be functional in both driver and non-driver present environment,but
+                                  it's per platform 
+                                  and enabling VariBri under the driver environment from PP table is optional.

-	 *     day/month/year calendar data.

-	 *     to set up as e.g. "alarm 15 minutes after each hour".
-	 *     Linux uses only oneshot alarms.
-	 *
-	 * When we see that here, we deal with it by using values from
-	 * a current RTC timestamp for any missing (-1) values.  The
-	 * RTC driver prevents "periodic alarm" modes.
-	 *
-	 * But this can be racey, because some fields of the RTC timestamp
-	 * may have wrapped in the interval since we read the RTC alarm,
-	 * which would lead to us inserting inconsistent values in place
-	 * of the -1 fields.
-	 *
-	 * Reading the alarm and timestamp in the reverse sequence
-	 * would have the same race condition, and not solve the issue.
-	 *
-	 * So, we must first read the RTC timestamp,
-	 * then read the RTC alarm value,
-	 * and then read a second RTC timestamp.
-	 *
-	 * If any fields of the second timestamp have changed
-	 * when compared with the first timestamp, then we know
-	 * our timestamp may be inconsistent with that used by
-	 * the low-level rtc_read_alarm_internal() function.
-	 *
-	 * So, when the two timestamps disagree, we just loop and do
-	 * the process again to get a fully consistent set of values.
-	 *
-	 * This could all instead be done in the lower level driver,
-	 * but since more than one lower level RTC implementation needs it,
-	 * then it's probably best best to do it here instead of there..

-BATMAN-ADV
-----------
-
-Batman  advanced  is  a new approach to wireless networking which
-does no longer operate on the IP basis. Unlike the batman daemon,
-which  exchanges  information  using UDP packets and sets routing
-tables, batman-advanced operates on ISO/OSI Layer 2 only and uses
-and  routes  (or  better: bridges) Ethernet Frames. It emulates a
-virtual network switch of all nodes participating.  Therefore all
-nodes  appear  to be link local, thus all higher operating proto-
-cols won't be affected by any changes within the network. You can
-run almost any protocol above batman advanced, prominent examples
-are: IPv4, IPv6, DHCP, IPX.
-
-Batman advanced was implemented as a Linux kernel driver  to  re-
-duce the overhead to a minimum. It does not depend on any (other)
-network driver, and can be used on wifi as well as ethernet  lan,
-vpn,  etc ... (anything with ethernet-style layer 2).
-
-CONFIGURATION
--------------
-
-Load the batman-adv module into your kernel:
-
-# insmod batman-adv.ko
-
-The  module  is now waiting for activation. You must add some in-
-terfaces on which batman can operate. After  loading  the  module
-batman  advanced  will scan your systems interfaces to search for
-compatible interfaces. Once found, it will create  subfolders  in
-the /sys directories of each supported interface, e.g.
-
-# ls /sys/class/net/eth0/batman_adv/
-# iface_status  mesh_iface
-
-If an interface does not have the "batman_adv" subfolder it prob-
-ably is not supported. Not supported  interfaces  are:  loopback,
-non-ethernet and batman's own interfaces.
-
-Note:  After the module was loaded it will continuously watch for
-new interfaces to verify the compatibility. There is no  need  to
-reload the module if you plug your USB wifi adapter into your ma-
-chine after batman advanced was initially loaded.
-
-To activate a  given  interface  simply  write  "bat0"  into  its
-"mesh_iface" file inside the batman_adv subfolder:
-
-# echo bat0 > /sys/class/net/eth0/batman_adv/mesh_iface
-
-Repeat  this step for all interfaces you wish to add.  Now batman
-starts using/broadcasting on this/these interface(s).
-
-By reading the "iface_status" file you can check its status:
-
-# cat /sys/class/net/eth0/batman_adv/iface_status
-# active
-
-To deactivate an interface you have  to  write  "none"  into  its
-"mesh_iface" file:
-
-# echo none > /sys/class/net/eth0/batman_adv/mesh_iface
-
-
-All  mesh  wide  settings  can be found in batman's own interface
-folder:
-
-#  ls  /sys/class/net/bat0/mesh/
-#  aggregated_ogms  bonding  orig_interval  vis_mode
-
-
-There is a special folder for debugging informations:
-
-#  ls /sys/kernel/debug/batman_adv/bat0/
-#  originators  socket  transtable_global  transtable_local
-#  vis_data
-
-
-Some of the files contain all sort of status information  regard-
-ing  the  mesh  network.  For  example, you can view the table of
-originators (mesh participants) with:
-
-# cat /sys/kernel/debug/batman_adv/bat0/originators
-
-Other files allow to change batman's behaviour to better fit your
-requirements.  For instance, you can check the current originator
-interval (value in milliseconds which determines how often batman
-sends its broadcast packets):
-
-# cat /sys/class/net/bat0/mesh/orig_interval
-# 1000
-
-and also change its value:
-
-# echo 3000 > /sys/class/net/bat0/mesh/orig_interval
-
-In very mobile scenarios, you might want to adjust the originator
-interval to a lower value. This will make the mesh  more  respon-
-sive to topology changes, but will also increase the overhead.
-
-
-USAGE
------
-
-To  make use of your newly created mesh, batman advanced provides
-a new interface "bat0" which you should use from this  point  on.
-All  interfaces  added  to  batman  advanced are not relevant any
-longer because batman handles them for you. Basically, one "hands
-over" the data by using the batman interface and batman will make
-sure it reaches its destination.
-
-The "bat0" interface can be used like any  other  regular  inter-
-face.  It needs an IP address which can be either statically con-
-figured or dynamically (by using DHCP or similar services):
-
-# NodeA: ifconfig bat0 192.168.0.1
-# NodeB: ifconfig bat0 192.168.0.2
-# NodeB: ping 192.168.0.1
-
-Note:  In  order to avoid problems remove all IP addresses previ-
-ously assigned to interfaces now used by batman advanced, e.g.
-
-# ifconfig eth0 0.0.0.0
-
-
-VISUALIZATION
--------------
-
-If you want topology visualization, at least one mesh  node  must
-be configured as VIS-server:
-
-# echo "server" > /sys/class/net/bat0/mesh/vis_mode
-
-Each  node  is  either configured as "server" or as "client" (de-
-fault: "client").  Clients send their topology data to the server
-next to them, and server synchronize with other servers. If there
-is no server configured (default) within the  mesh,  no  topology
-information   will  be  transmitted.  With  these  "synchronizing
-servers", there can be 1 or more vis servers sharing the same (or
-at least very similar) data.
-
-When  configured  as  server,  you can get a topology snapshot of
-your mesh:
-
-# cat /sys/kernel/debug/batman_adv/bat0/vis_data
-
-This raw output is intended to be easily parsable and convertable
-with  other tools. Have a look at the batctl README if you want a
-vis output in dot or json format for instance and how those  out-
-puts could then be visualised in an image.
-
-The raw format consists of comma separated values per entry where
-each entry is giving information about a  certain  source  inter-
-face.  Each  entry can/has to have the following values:
--> "mac" - mac address of an originator's source interface
-           (each line begins with it)
--> "TQ mac  value"  -  src mac's link quality towards mac address
-                       of a neighbor originator's interface which
-                       is being used for routing
--> "HNA mac" - HNA announced by source mac
--> "PRIMARY" - this  is a primary interface
--> "SEC mac" - secondary mac address of source
-               (requires preceding PRIMARY)
-
-The TQ value has a range from 4 to 255 with 255 being  the  best.
-The HNA entries are showing which hosts are connected to the mesh
-via bat0 or being bridged into the mesh network.  The PRIMARY/SEC
-values are only applied on primary interfaces
-
-
-LOGGING/DEBUGGING
------------------
-
-All error messages, warnings and information messages are sent to
-the kernel log. Depending on your operating  system  distribution
-this  can  be read in one of a number of ways. Try using the com-
-mands: dmesg, logread, or looking in the files  /var/log/kern.log
-or  /var/log/syslog.  All  batman-adv  messages are prefixed with
-"batman-adv:" So to see just these messages try
-
-# dmesg | grep batman-adv
-
-When investigating problems with your mesh network  it  is  some-
-times  necessary  to see more detail debug messages. This must be
-enabled when compiling the batman-adv module. When building  bat-
-man-adv  as  part of kernel, use "make menuconfig" and enable the
-option "B.A.T.M.A.N. debugging".
-
-Those additional  debug messages can be accessed  using a special
-file in debugfs
-
-# cat /sys/kernel/debug/batman_adv/bat0/log
-
-The additional debug output is by default disabled. It can be en-
-abled  during run time. Following log_levels are defined:
-
-0 - All  debug  output  disabled
-1 - Enable messages related to routing / flooding / broadcasting
-2 - Enable route or hna added / changed / deleted
-3 - Enable all messages
-
-The debug output can be changed at runtime  using  the  file
-/sys/class/net/bat0/mesh/log_level. e.g.
-
-# echo 2 > /sys/class/net/bat0/mesh/log_level
-
-will enable debug messages for when routes or HNAs change.
-
-
-BATCTL
-------
-
-As batman advanced operates on layer 2 all hosts participating in
-the  virtual switch are completely transparent for all  protocols
-above layer 2. Therefore the common diagnosis tools do  not  work
-as  expected.  To  overcome these problems batctl was created. At
-the  moment the  batctl contains ping,  traceroute,  tcpdump  and
-interfaces to the kernel module settings.
-
-For more information, please see the manpage (man batctl).
-
-batctl is available on http://www.open-mesh.org/

-Description:
-                Each batman node only maintains information about its

-                the local topologies from all nodes. This file allows
-                to activate the collecting (server) mode.

-KNOWN BUILD PROBLEMS
+KNOWN RUNTIME ISSUES
 --------------------
 
-(1) Recent gcc versions may generate the message:
+(1) Intentionally, this driver will not stream material which is unambiguously
+identified by the hardware as copy-protected.  Normal video output will be
+present for about a minute but will then freeze when this situation arises.
 
-     warning: the frame size of .... bytes is larger than 1024 bytes
+(2) The controls for luminance, contrast, saturation, hue and volume may not
+always work properly.
 
-This warning can be suppressed by specifying in the Makefile:
+(3) Reduced-resolution S-Video seems to suffer from moire artefacts.
 
-     EXTRA_CFLAGS += -Wframe-larger-than=8192
 
-but it would be preferable to remove the cause of the warning.
+INPUT NUMBERING
+---------------
 
+For the EasyCAP with S-VIDEO input cable the driver regards a request for
+inputs numbered 0 or 1 as referring to CVBS and a request for input
+numbered 5 as referring to S-VIDEO.
 
-KNOWN RUNTIME ISSUES
---------------------
+For the EasyCAP with four CVBS inputs the driver expects to be asked for
+any one of inputs numbered 1,2,3,4.  If input 0 is asked for, it is
+interpreted as input 1.
 
-(1) Randomly (maybe 5 to 10% of occasions) the driver fails to produce any
-output at start-up.  Closing mplayer (or whatever the user program is) and
-restarting it restores normal performance without any other remedial action
-being necessary.  The reason for this is not known.
 
-(2) Intentionally, this driver will not stream material which is unambiguously
-identified by the hardware as copy-protected.  The video output will freeze
-within about a minute when this situation arises.
+MODULE PARAMETERS
+-----------------
 
-(3) The controls for luminance, contrast, saturation, hue and volume may not
-always work properly.
+Three module parameters are defined:
 
-(4) Reduced-resolution S-Video seems to suffer from moire artefacts.  No
-attempt has yet been made to rememdy this.

-		stored in a 64 bit location aligned to a a64 bit boundary.
+		and hence the form in which it is read from user-space.
+		Form is [s|u]bits/storagebits[>>shift].  s or u specifies if
+		signed (2's complement) or unsigned. bits is the number of bits
+		of data and storagebits is the space (after padding) that it
+		occupies in the buffer. shift if specified, is the shift that
+		needs to be applied prior to masking out unused bits. Some
+		devices put their data in the middle of the transferred elements
+		with additional information on both sides.  Note that some
+		devices will have additional information in the unused bits
+		so to get a clean value, the bits value must be used to mask
+		the buffer output value appropriately.  The storagebits value
+		also specifies the data alignment.  So s48/64>>2 will be a
+		signed 48 bit integer stored in a 64 bit location aligned to
+		a a64 bit boundary. To obtain the clean value, shift right 2
+		and apply a mask to zero the top 16 bits of the result.
 		For other storage combinations this attribute will be extended
 		appropriately.
