神龙卡开发原代码

2003-06-12  Emmanuel Michon  <[e-mail]>

	* added CC data fetching in userland. Note: happening FETCHCC has to be
	processed quickly because there is only one 128 bytes buffer.
	Reference implementation in fetchcc.c, ok with sony-ct4.mp2

2003-05-13  Emmanuel Michon  <[e-mail]>

	* RUA version 102

	* added aspect ratio happening (fix for WEGA Q3)

	* fixed rm84cmn.h for hwtest/audioin sets inversion (fix for WEGA MR1)

2003-04-18  Emmanuel Michon  <[e-mail]>

	* RUA version 101

	* RUA version 100

	* merging HAC/HVC registry programming

	* merging HAC/HVC capture & encoder reset handling

	* merging HAC/HVC evOutDisplayOption

	* merging HAC/HVC WITH_DMARESERVEDAREA patch 
	(only one board is supported in this case)

2003-04-16  Emmanuel Michon  <[e-mail]>

	* RUA version 99

	* more kc_ functions (cache flushing for PPC. read/write on b/l/w)

2003-03-25  Emmanuel Michon  <[e-mail]>

	* RUA version 98

	* fixed makefile

	* fix for SW26

2003-03-17  Emmanuel Michon  <[e-mail]>

	* RUA version 97

	* CompletePalette osdbuf kernel property to set palette at once

2003-03-04  Emmanuel Michon  <[e-mail]>

	* RUA version 96

	* getting rid of clear_mask (pain for portability)

	* happening mask does not need to be a atomic_t

2003-01-28  Emmanuel Michon  <[e-mail]>

	* new property MKERNELOSDBUFOTFDimensions (OTF stands for On The Fly) to
	change dynamically the size of the osdbuf, and `-s' switch in osdbuf_fb_control application.
	Restrictions:
	- required size must be smaller than the size given when osdbuf was enabled
	- if width changes, image will distorted
	- this is not compatible with the use of realmagichwl_kernelland_fb.o

2003-01-22  Emmanuel Michon  <[e-mail]>

	* RUA version 92

	* video frames skipping logging in decoder tasklet (code by Mathieu Lacage)

	* exporting the minimum symbols for use of osdbuf/yuvbuf on top of the base module

2003-01-09  Emmanuel Michon  <[e-mail]>

	* RUA version 91

	* mpegcmn.h and mpegerr.h have disappeared in hwl. Most types moved
	to rm84cmn.h and now there is rm84cmn_wrapper.h to include quickly this file
	
	* cleaning up, braces alignment, conditional for no SM2288 configurations
	
	* merging Sony approved support for SM2288 interrupts

	* quasar ucode version 0x12f

	* sm2288 ucode version 0x546

2002-12-24  Emmanuel Michon  <[e-mail]>

	* RUA version 90 (sm2288 0x545, quasar 0x12c)

	* using only one of the two ping-pong buffers

	* tasklet protects against tophalf (irqsave/irqrestore in hwlprivate.c)

	* removing timing measures from encoder code

	* merging changes with Hiraku Inoue about not using DMA_DONE

2002-12-22  Emmanuel Michon  <[e-mail]>

	* request_irq now uses SA_INTERRUPT (trying to fix HAC interrupt miss problem)
	`slow' handlers allow the interrupt routine of x to be interrupted by y!=x (ex.
	x=quasar and y=keyboard or y=network or y=harddisk)
	`fast' handlers (SA_INTERRUPT) run with interrupts totally disabled

	If a hardware irq on line x happens during processing of x,
	whatever the handler type, the irq is lost (see Rubini)

2002-12-20  Emmanuel Michon  <[e-mail]>

	* RUA version 89

	* transmission of DISPLAY_READY_INTERRUPT as REALMAGICHWL_HAPPENING_DECODER_DISPLAYREADY happening

	* sm2288 ucode update 0x540

2002-12-09  Emmanuel Michon  <[e-mail]>

	* RUA version 82

	* implemented OSD_INTERRUPT

	* Encoder action: ENCODER_ONTHEFLYAPPLY has changed to ENCODER_PARAMSAPPLY.
	This is now _mandatory_	to call ENCODER_PARAMSAPPLY, then wait for
	ENCODER_PARAMSDOWNLOADED happening, to run ENCODER_START safely

2002-12-06  Emmanuel Michon  <[e-mail]>

	* RUA version 81

	* default MAXPROBEDQUASARS is now 10, and memory zone used is
	proportional.  If you know you have only one device to support
	(set to box) put 1 here (to save RAM).  If you need more than
	this, increase (limit is how fast the hosting PC is able to handle
	them)
		
	* RUA version 80

	* fixed slideshow sync code, thanks Vincent

2002-12-05  Emmanuel Michon  <[e-mail]>

2002-12-04  Emmanuel Michon  <[e-mail]>

	* moved kernel calls to a specific file. All kernel calls are now
	wrapped by a kc_... function. This should allow to use any compiler for
	binary releases
