* fl2k_tcp: don't free buffer while lib still uses itSteve Markgraf2019-08-261-1/+1
| | | | | This sometimes caused a segfault when terminating fl2k_tcp.
* improve exit handling on device removalSteve Markgraf2019-08-265-11/+35
|
* lib: wait for sample worker thread before freeing buffersSteve Markgraf2019-08-251-0/+2
| | | | | | | This fixes a segfault when exiting, as sometimes it occured that the USB worker thread completed before the sample worker thread, and the buffers the latter was still accessing had already been freed.
* fl2k_file: check read return value before repeatingSteve Markgraf2019-08-251-1/+1
| | | | | In case of a FIFO that has been closed or a 0 byte file this will otherwise lead to an endless loop.
* fl2k_fm: make inline functions staticSteve Markgraf2019-08-251-7/+7
| | | | | Otherwise the linker will complain when building with -DCMAKE_BUILD_TYPE=Debug
* contrib/jenkins.sh: osmo-fl2k build verificationOliver Smith2019-08-011-0/+18

* lib: Add workaround for Linux usbfs mmap() bugSteve Markgraf2018-10-071-2/+17
| | | | | | | | | | | | The Linux Kernel has a bug on ARM/ARM64 systems where the USB CMA memory is incorrectly mapped to userspace, breaking zerocopy. When the Kernel allocates the memory, it clears it with memset(). If the mapping worked correctly, we should have zeroed out buffers, if it doesn't, we get random Kernel memory. We now check for this, and fall back to buffers in userspace if that's the case. Signed-off-by: Steve Markgraf <steve@steve-m.de>
* lib: add I2C supportSteve Markgraf2018-06-172-0/+136
| | | | | | | Note that the FL2000 only supports I2C transfers with a fixed length of 4 bytes. Signed-off-by: Steve Markgraf <steve@steve-m.de>

* debian: build-dep on dh-autoreconf for Ubuntu 16.04/Debian8Harald Welte2018-06-031-1/+1
| | | | | | | | | | according to https://wiki.debian.org/Autoreconf: ... dh-autoreconf is enabled by default since debhelper compatibility level 10 (and the debhelper package Depends on dh-autoreconf since version 9.20160402). For lower compatibility levels: * Build-Depend on dh-autoreconf ...
* debian: Attempt to down-grade the debhelper version requirementHarald Welte2018-06-032-2/+2
| | | | ... so we can build on anything except unstable + ubuntu 18.04
* Add Debian packaging informationHarald Welte2018-06-0310-0/+187
| | | | | | This allows (among others) to build rtl-sdr nightly packages for a variety of distributions as part of the network:osmocom:nightly builds.
* enable multiarch build by means of GNUInstallDirsThorsten Alteholz2018-06-032-3/+7
| | | | This patch is taken from the osmo-fl2k debian package.
* libusb-1.0.22 deprecated libusb_set_debug() with libusb_set_option()Harald Welte2018-06-031-0/+4
| | | | | | | | | | | This avoids the following compiler warnings when using more recent versions of libusb: src/libosmo-fl2k.c:384:2: warning: ‘libusb_set_debug’ is deprecated: Use libusb_set_option instead [-Wdeprecated-declarations] libusb_set_debug(dev->ctx, 3); ^~~~~~~~~~~~~~~~ Details can be found at https://github.com/libusb/libusb/commit/539f22e2fd916558d11ab9a66f10f461c5593168
