Bert Vermeulen d6836bf129 fx2lafw: Adjust to GVariant-based sr_config_* functions 2013-04-11 18:32:06 +02:00

Uwe Hermann 3e9b7f9c77 Rename session_dev_id to cb_data everywhere.
We use 'cb_data' in all drivers these days, make the few remaining ones
that use 'session_dev_id' consistent.

Uwe Hermann 4afdfd4628 Add and use std_session_send_df_header().
This is a small helper function which sends the SR_DF_HEADER packet that
drivers usually emit in their hw_dev_acquisition_start() API callback.
It simplifies and shortens the hw_dev_acquisition_start() functions
quite a bit.

It also simplifies the input modules which send an SR_DF_HEADER packet, too.

This patch also automatically removes some unneeded malloc/free in some
drivers for the 'packet' and 'header' structs used for SR_DF_HEADER.

Uwe Hermann 961009b0c4 hw_dev_close(): Move common checks to wrapper.
Check the relevant arguments for != NULL before calling the actual
driver-specific function, so that the driver can safely assume those
arguments are non-NULL. This removes the need to duplicate these
checks in every driver.

Uwe Hermann d3b38ad389 Drivers: Explicitly list sr_samplerates fields.
This makes it a bit easier to understand which value means what, just
from looking at the driver code.
2013-01-29 12:56:02 +01:00
Uwe Hermann 063e7aef6d Factor out common hw_init() driver code.
Most drivers do pretty much the same things in their hw_init()
right now, so factor out that code to std_hw_init() in std.c.

Bert Vermeulen 1987b8d63e drivers: use new sr_config struct
Sending an SR_DF_META packet at the start of every stream is not
mandatory; the frontend should ask for what it needs, and any extra
information the driver wants to send will come in due time.
2013-01-21 23:32:49 +01:00
Bert Vermeulen 6b8d6f93bb Get rid of obsolete SR_DI_NUM_PROBES and SR_DI_PROBE_NAMES.
Frontends should use the probe list in the device's sr_dev_inst
to get this information.

Use 'di' consistently in all drivers as the name for a local, static
pointer to the respective driver's 'struct sr_dev_driver'.

Alexandru Gagniuc 443a14d81f fx2lafw: Print device failed to renumerate error
commit 378abfeac6 tried to solve a bug where
the fx2lafw driver would print "Device came back" even if a timeout had occured.

It solved that issue, but inadvertently introduced a new bug:
"Device came back" would be printed even if no firmware upload was performed.
This is counterintuitive, as the device is only reset when a firmware upload is
performed.

There are three cases:
i)   Firmware upload was successful
ii)  Firmware upload failed
iii) Firmware upload was NOT needed

Each case warrants a separate message from the driver. Print the
following messages depending on the outcome:

i)   "Device came back"
ii)  "Device failed to renumerate"
iii) "Firmware upload was not needed."

Alexandru Gagniuc f427daefb0 fx2lafw: Use DRIVER_LOG_DOMAIN for log messages
Use the new DRIVER_LOG_DOMAIN mechanism, where explicitly writing
the driver name in the message string is no longer required.

Thus:

- sr_err("fx2lafw: Something bad happened.");

becomes:

+ sr_err("Something bad happened.");

In either case, the log output is the same.

Bert Vermeulen 69b07d14db allow for intermediate stage in stopping acquisition
In the case of USB drivers, a driver's dev_acquisition_stop() cannot
simply remove its fd sources from the session and close its devices:
a USB transfer might still be underway, and it needs to be finished
(and its memory freed) properly.

An sr_dev_inst->status value is added: SR_ST_STOPPING, which should
be set when the driver's dev_acquisition_stop() is called, and acts
as a marker for the USB event handler to wind up its operations.

In order for dev_acquisition_stop() to be able to set the sdi status,
however, it needs to be unconstified.

Bert Vermeulen 811deee4af sr/drivers: add API calls sr_dev_inst_list() and sr_dev_inst_clear()
These are used to list the device instances currently known to the driver,
and clear that list.

Drivers that don't necessarily clear their list of instances on every scan,
such as genericdmm, need to provide these to the frontend to keep instance
management sane.

Bert Vermeulen 014359e329 sr/drivers: obsolete SR_HWCAP_PROBECONFIG
Since probes now live in a struct sr_dev_inst owned by the driver, it
already knows about them. Instead of a frontend telling the driver to
configure probes, all driver now do this just before starting acquisition.

It's obsolete: no frontend ever used it, and neither did libsigrok.

should probably be moved to the driver-specific context structs.
