http://linuxtv.org/hg/v4l-dvb/rev/698119141230 and other CI-stuff seems to
break saa7113 capture
with xawtv (says driver refuses to capture) on at least KNC1 dvb-c plus, can
anyone confirm this?
1. weird reset/Vcc control code:
/* GPIO Connections:
* 0 - Vcc/(#)Reset(?) (Reset is controlled by capacitor). Resets the frontend
(and the saa7113?) *AS WELL*!
static int ciintf_slot_reset(struct dvb_ca_en50221 *ca, int slot)
{
struct budget_av *budget_av = (struct budget_av *) ca->data;
struct saa7146_dev *saa = budget_av->budget.dev;
if (slot != 0)
return -EINVAL;
dprintk(1, "ciintf_slot_reset\n");
budget_av->slot_status = SLOTSTATUS_RESET;
saa7146_setgpio(saa, 2, SAA7146_GPIO_OUTHI); /* disable card */
saa7146_setgpio(saa, 0, SAA7146_GPIO_OUTHI); /* Vcc off */
msleep(2);
saa7146_setgpio(saa, 0, SAA7146_GPIO_OUTLO); /* Vcc on */
msleep(20); /* 20 ms Vcc settling time */
saa7146_setgpio(saa, 2, SAA7146_GPIO_OUTLO); /* enable card */
ttpci_budget_set_video_port(saa, BUDGET_VIDEO_PORTB);
msleep(20);
static int ciintf_slot_ts_enable(struct dvb_ca_en50221 *ca, int slot)
{
...
ttpci_budget_set_video_port(saa, BUDGET_VIDEO_PORTA);
(Q: to what saa7146 video port is the saa7113 output connected?)
static int ciintf_init(struct budget_av *budget_av)
{
struct saa7146_dev *saa = budget_av->budget.dev;
int result;
memset(&budget_av->ca, 0, sizeof(struct dvb_ca_en50221));
saa7146_setgpio(saa, 0, SAA7146_GPIO_OUTLO);
saa7146_setgpio(saa, 1, SAA7146_GPIO_OUTLO);
saa7146_setgpio(saa, 2, SAA7146_GPIO_OUTLO);
saa7146_setgpio(saa, 3, SAA7146_GPIO_OUTLO);
static void ciintf_deinit(struct budget_av *budget_av)
{
struct saa7146_dev *saa = budget_av->budget.dev;
saa7146_setgpio(saa, 0, SAA7146_GPIO_INPUT);
saa7146_setgpio(saa, 1, SAA7146_GPIO_INPUT);
saa7146_setgpio(saa, 2, SAA7146_GPIO_INPUT);
saa7146_setgpio(saa, 3, SAA7146_GPIO_INPUT);
(Q: why is all that CI and tuner frontend (which budget card has got a analogtv
demod?)
code in the budget__AV__ module ?
pls move it to budget__CI__ and budget modules, and have the budget_av/_ci
modules
detected there and loaded and utilized *if* needed and clean up saa7113
interfering detection code, thx)
will surely kill:
static int saa7113_init(struct budget_av *budget_av)
{
struct budget *budget = &budget_av->budget;
struct saa7146_dev *saa = budget->dev;
const u8 *data = saa7113_tab;
saa7146_setgpio(saa, 0, SAA7146_GPIO_OUTHI);
msleep(200);
and further:
if ((err = saa7146_register_device(&budget_av->vd, dev, "knc1",
VFL_TYPE_GRABBER))) {
static struct v4l2_input knc1_inputs[KNC1_INPUTS] = {
{0, "Composite", V4L2_INPUT_TYPE_TUNER, 1, 0, V4L2_STD_PAL_BG |
V4L2_STD_NTSC_M, 0},
{1, "S-Video", V4L2_INPUT_TYPE_CAMERA, 2, 0, V4L2_STD_PAL_BG |
V4L2_STD_NTSC_M, 0},
};
grabber device setup with no capture and format ioctls
static struct saa7146_extension_ioctls ioctls[] = {
{VIDIOC_ENUMINPUT, SAA7146_EXCLUSIVE},
{VIDIOC_G_INPUT, SAA7146_EXCLUSIVE},
{VIDIOC_S_INPUT, SAA7146_EXCLUSIVE},
{0, 0}
};
and no capture caps:
static struct saa7146_ext_vv vv_data = {
.inputs = 2,
.capabilities = 0, // perhaps later: V4L2_CAP_VBI_CAPTURE, but
that need tweaking with the saa7113
(Q: what tweaking? -> av7110_v4l.c...)
so no grabbing from the saa7113 at all? is this untried draft code? nobody
using it?
then I will see if this proves saa7146 GPIO issues from CI code:
