In particular, when that task ++ * executes, we want to freeze that task and only that task. ++ * ++ * The bits of the debug control register influence interrupts vs. ++ * breakpoints as follows: ++ * - Bits 14 and 0 enable or disable debug functions. If enabled, you ++ * will get the interrupt but you may or may not get a breakpoint. ++ * - Bits 2 and 1 decide whether you also get a breakpoint in addition ++ * to an interrupt. ++ * ++ * The debug unit can do these actions in response to either internally ++ * detected breakpoint conditions from the comparators, or in response ++ * to the external breakpoint pin, or both. ++ * - Bits 14 and 1 perform the above-described functions for ++ * internally-generated conditions, i.e., the debug comparators. ++ * - Bits 0 and 2 perform the above-described functions for external ++ * conditions, i.e., the breakpoint external pin. ++ * ++ * Note that, although you "always" get the interrupt when you turn ++ * the debug functions, the interrupt can nevertheless, if desired, be ++ * masked by the corresponding bit in the PTD's IMR. Note also that ++ * this means that bits 14 and 0 must enable debug functions before ++ * bits 1 and 2, respectively, have any effect. ++ * ++ * NOTE: It's extremely important to not pause more than one DMA channel ++ * at a time. ++ ********************************************************************/ ++ ++/********************************************************************/ ++/* Function: MCD_pauseDma ++ * Purpose: Pauses the DMA on a given channel (if any DMA is running ++ * on that channel). ++ * Arguments: channel ++ * Returns: MCD_CHANNEL_INVALID if channel is invalid, else MCD_OK ++ */ ++int MCD_pauseDma (int channel) ++{ ++ if((channel < 0) || (channel >= NCHANNELS)) ++ return(MCD_CHANNEL_INVALID); ++ ++ if (MCD_dmaBar->taskControl[channel] & TASK_CTL_EN) ++ { ++ MCD_dmaBar->debugComp1 = channel; ++ MCD_dmaBar->debugControl = DBG_CTL_ENABLE | (1 << (channel + 16)); ++ MCD_chStatus[channel] = MCD_PAUSED; ++ } ++ return(MCD_OK); ++} ++/************************* End of MCD_pauseDma() ********************/ ++ ++/********************************************************************/ ++/* Function: MCD_resumeDma ++ * Purpose: Resumes the DMA on a given channel (if any DMA is ++ * running on that channel). ++ * Arguments: channel - channel on which to resume DMA ++ * Returns: MCD_CHANNEL_INVALID if channel is invalid, else MCD_OK ++ */ ++int MCD_resumeDma (int channel) ++{ ++ if((channel < 0) || (channel >= NCHANNELS)) ++ return(MCD_CHANNEL_INVALID); ++ ++ if (MCD_dmaBar->taskControl[channel] & TASK_CTL_EN) ++ MCD_resmActions (channel); ++ ++ return(MCD_OK); ++} ++/************************ End of MCD_resumeDma() ********************/ ++ ++/********************************************************************/ ++/* Function: MCD_csumQuery ++ * Purpose: Provide the checksum after performing a non-chained DMA ++ * Arguments: channel - channel to report on ++ * csum - pointer to where to write the checksum/CRC ++ * Returns: MCD_ERROR if the channel is invalid, else MCD_OK ++ * ++ * Notes: ++ * ++ */ ++int MCD_csumQuery (int channel, u32 *csum) ++{ ++#ifdef MCD_INCLUDE_EU ++ if((channel < 0) || (channel >= NCHANNELS)) ++ return(MCD_CHANNEL_INVALID); ++ ++ *csum = MCD_relocBuffDesc[channel].csumResult; ++ return(MCD_OK); ++#else ++ return(MCD_ERROR); ++#endif ++} ++/*********************** End of MCD_resumeDma() *********************/ ++ ++/********************************************************************/ ++/* Function: MCD_getCodeSize ++ * Purpose: Provide the size requirements of the microcoded tasks ++ * Returns: Size in bytes ++ */ ++int MCD_getCodeSize(void) ++{ ++#ifdef MCD_INCLUDE_EU ++ return(0x2b64); ++#else ++ return(0x1744); ++#endif ++} ++/********************** End of MCD_getCodeSize() ********************/ ++ ++/********************************************************************/ ++/* Function: MCD_getVersion ++ * Purpose: Provide the version string and number ++ * Arguments: longVersion - user supplied pointer to a pointer to a char ++ * which points to the version string ++ * Returns: Version number and version string (by reference) ++ */ ++char MCD_versionString[] = "Multi-channel DMA API v1.0"; ++#define MCD_REV_MAJOR 0x01 ++#define MCD_REV_MINOR 0x00 ++ ++int MCD_getVersion(char **longVersion) ++{ ++ *longVersion = MCD_versionString; ++ return((MCD_REV_MAJOR << 8) | MCD_REV_MINOR); ++} ++/********************** End of MCD_getVersion() *********************/ ++ ++/********************************************************************/ ++/* Private version of memcpy() ++ * Note that everything this is used for is longword-aligned. ++ */ ++static void MCD_memcpy (int *dest, int *src, u32 size) ++{ ++ u32 i; ++ ++ for (i = 0; i < size; i += sizeof(int), dest++, src++) ++ *dest = *src; ++} ++/********************************************************************/ +--- /dev/null ++++ b/drivers/dma/MCD_dma.h +@@ -0,0 +1,378 @@ ++/* ++ * drivers/dma/MCD_dma.h ++ * ++ * Copyright (C) 2004-2008 Freescale Semiconductor, Inc. ++ * Kurt Mahan <kmahan@freescale.com> ++ * ++ * This program is free software; you can redistribute it and/or ++ * modify it under the terms of the GNU General Public License as ++ * published by the Free Software Foundation; either version 2 of ++ * the License, or (at your option) any later version. ++ * ++ * This program is distributed in the hope that it will be useful, ++ * but WITHOUT ANY WARRANTY; without even the implied warranty of ++ * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
