I'm seeing the kernel -generate extra "unclick" events in these cases. It looks like in the -driver, an unclick event is processed before the click event, thus -suppressing the click from ever being generated. I'm attaching a patch -that addresses this. I'm now able to type much faster on the matchbox -keyboard, even when using my fingertips instead of fingernails. - -Dima - -Signed-off-by: Dima Kogan <dkogan@cds.caltech.edu> ---- - drivers/input/touchscreen/s3c2410_ts.c | 17 +++++++++++++++++ - 1 files changed, 17 insertions(+), 0 deletions(-) - -diff --git a/drivers/input/touchscreen/s3c2410_ts.c b/drivers/input/touchscreen/s3c2410_ts.c -index 9fb95c1..fc1c500 100644 ---- a/drivers/input/touchscreen/s3c2410_ts.c -+++ b/drivers/input/touchscreen/s3c2410_ts.c -@@ -118,6 +118,7 @@ struct s3c2410ts { - struct s3c2410ts_sample raw_running_avg; - int reject_threshold_vs_avg; - int flag_previous_exceeded_threshold; -+ int flag_first_touch_sent; - }; - - static struct s3c2410ts ts; -@@ -130,6 +131,7 @@ static void clear_raw_fifo(void) - ts.raw_running_avg.x = 0; - ts.raw_running_avg.y = 0; - ts.flag_previous_exceeded_threshold = 0; -+ ts.flag_first_touch_sent = 0; - } - - -@@ -153,6 +155,19 @@ static void touch_timer_fire(unsigned long data) - updown = (!(data0 & S3C2410_ADCDAT0_UPDOWN)) && - (!(data1 & S3C2410_ADCDAT0_UPDOWN)); - -+ // if we need to send an untouch event, but we haven't yet sent the -+ // touch event (this happens if the touchscreen was tapped lightly), -+ // send the touch event first -+ if (!updown && !ts.flag_first_touch_sent && ts.count != 0) { -+ input_report_abs(ts.dev, ABS_X, ts.xp >> ts.shift); -+ input_report_abs(ts.dev, ABS_Y, ts.yp >> ts.shift); -+ -+ input_report_key(ts.dev, BTN_TOUCH, 1); -+ input_report_abs(ts.dev, ABS_PRESSURE, 1); -+ input_sync(ts.dev); -+ ts.flag_first_touch_sent = 1; -+ } -+ - if (updown) { - if (ts.count != 0) { - ts.xp >>= ts.shift; -@@ -174,6 +189,7 @@ static void touch_timer_fire(unsigned long data) - input_report_key(ts.dev, BTN_TOUCH, 1); - input_report_abs(ts.dev, ABS_PRESSURE, 1); - input_sync(ts.dev); -+ ts.flag_first_touch_sent = 1; - } - - ts.xp = 0; -@@ -190,6 +206,7 @@ static void touch_timer_fire(unsigned long data) - input_report_key(ts.dev, BTN_TOUCH, 0); - input_report_abs(ts.dev, ABS_PRESSURE, 0); - input_sync(ts.dev); -+ ts.flag_first_touch_sent = 0; - - writel(WAIT4INT(0), base_addr+S3C2410_ADCTSC); - } --- -1.5.6.5 - |
