CRE_FLGについて (2004-08-24 15:36 by Anonymous #10725)

また初歩的な質問ですみません。
静的生成でIDを連続した番号でなく飛び飛びな番号で生成可能でしょうか？

連続しない番号の場合、セマフォオブジェクトがアロケートされていないエリアまで初期化されているような気がします。動的生成の場合もHOS_MAX_FLGIDで指定した範囲を初期化してしまうようです。

すみません、セマフォでなくてフラグの場合です。

試しに
HOS_MAX_FLGID(16);

CRE_FLG(FID_RTLINT, {TA_TFIFO | TA_WSGL , 0});
CRE_FLG(FID_RTLINTSND, {TA_TFIFO | TA_WSGL , 0});
CRE_FLG(FID_RTLINTOVW, {TA_TFIFO | TA_WSGL , 0});
CRE_FLG(10, {TA_TFIFO | TA_WSGL , 0});
CRE_FLG(12, {TA_TFIFO | TA_WSGL , 0});
CRE_FLG(14, {TA_TFIFO | TA_WSGL , 0});
CRE_FLG(16, {TA_TFIFO | TA_WSGL , 0});

と書いて、コンフィギュレータ－に掛けたら、
/* ------------------------------------------ */
/* create event flag objects */
/* ------------------------------------------ */

/* event flag control block for rom area */
const T_KERNEL_FLGCB_ROM kernel_flgcb_rom[7] =
{
{(ATR)(TA_TFIFO | TA_WSGL), (FLGPTN)(0)},
{(ATR)(TA_TFIFO | TA_WSGL), (FLGPTN)(0)},
{(ATR)(TA_TFIFO | TA_WSGL), (FLGPTN)(0)},
{(ATR)(TA_TFIFO | TA_WSGL), (FLGPTN)(0)},
{(ATR)(TA_TFIFO | TA_WSGL), (FLGPTN)(0)},
{(ATR)(TA_TFIFO | TA_WSGL), (FLGPTN)(0)},
{(ATR)(TA_TFIFO | TA_WSGL), (FLGPTN)(0)},
};

/* event flag control block for ram area */
T_KERNEL_FLGCB_RAM kernel_flgcb_ram[7];

/* event flag control block table */
T_KERNEL_FLGCB_RAM *kernel_flgcb_ram_tbl[16] =
{
&kernel_flgcb_ram[0],
&kernel_flgcb_ram[1],
&kernel_flgcb_ram[2],
NULL,
NULL,
NULL,
NULL,
NULL,
NULL,
&kernel_flgcb_ram[3],
NULL,
&kernel_flgcb_ram[4],
NULL,
&kernel_flgcb_ram[5],
NULL,
&kernel_flgcb_ram[6],
};

/* event flag control block count */
const INT kernel_flgcb_cnt = 16;

と生成してきたのですが、そう言う事ではなくて？。

しかし、実際にIDを飛び飛びに設定して、正しく動くかどうかまでは確認していません。
誰かやった人、居ます？。

すみません、回答ありがとうございます。
ソースのkernel_ini_flgを見るとNULLをチェックしていないので、単純にIDの最初から順番に初期化されるのではないでしょうか？

確かに、他のセマとかタスクの場合はNULLのチェックが入っていますね。
KERNEL_FLGID_TO_FLGCB_RAM(i)->flgptn = KERNEL_FLGID_TO_FLGCB_RAM(i)->flgcb_rom->iflgptn;
なので、コンフィギュレータでNULLに初期化されている領域の代入を行った場合、特に0番地がROMでは無いシステムの場合は、問題が有るかも。

セマのコードをぱくって、
if ( KERNEL_FLGID_TO_FLGCB_RAM(i) != NULL )
KERNEL_FLGID_TO_FLGCB_RAM(i)->flgptn = KERNEL_FLGID_TO_FLGCB_RAM(i)->flgcb_rom->iflgptn;

となるのでしょうか？。
そろそろm-araiさんの登場の予感。
