PyLance not working in VS Code on Arch Linux - visual-studio-code

After installing the Python extension for VS Code, PyLance doesn't automatically install. After changing python.languageServer to PyLance, VS code now prompts me with the following.
After clicking Install Pylance, it seems like nothing happens. Here are the logs (after setting log level to Trace)

Build AOSP on MacOS M1

I wanted to get my feet wet with AOSP on my MacOS M1 (ARM64) with Big Sur, but it looks like there is no configuration build for this host.
When I look under build/soong/cc/config I only see one Darwin related file, namely x86_darwin_host.go.
With the latest aosp release, namely android-11.0.0_r35 I'm able to build a generic arm64 target, but the resulting emulator does not boot. Configuration shows that the HOST is detected as x86_64, in fact binaries generated are in x86_64 format.

Any idea how I can debug what is wrong with the initrd image?
I think this should help, it has a peace specific for setup the missing sdk 10.15.
Good luck, let us know if it works to you!

comand "lspci" does not show the the IVSHMEM device

I met a problem when I tried to use IVSHMEM.
Below is the configuration from my side:
vm xml configuration for IVSHMEM device:
<shmem name='ivshmem'>
<model type='ivshmem-plain'/>
<size unit='M'>2</size>
<address type='pci' domain='0x0000' bus='0x00' slot='0x10' function='0x0'/>
</shmem>
after the booting up and I found the qemu commandline ideedly have the device option:
ps aux | grep ivshmem
/usr/bin/qemu-system-x86_64
.......(ignore other options)
-object memory-backend-file,id=shmmem-shmem0,mem-path=/dev/shm/hostmem,size=4194304,share=yes -device ivshmem-plain,id=shmem0,memdev=shmmem-shmem0,bus=pcie.0,addr=0x10
lspci command not shown the device.
lshw command indeedly show the device:

Anything input on this one?
You first need to load the generic driver:
modprobe uio_pci_generic
Then you will see the PCI device.
Afterwards you can load your own kernel module by using
insmod uio_ivshmem.ko
Note that you probably need to build the module first.

Unable to install and configure a J-Link JTAG debugger on a Mac

I have a Segger J-Link which I am trying to use on a Macbook running MacOS Catalina 10.15.4, with openocd and GDB against an ESP32 board. The problem is that I can not seen the device:
$ ls /dev/cu.*
/dev/cu.Bluetooth-Incoming-Port /dev/cu.JimsiPhone-WirelessiAP /dev/cu.SLAB_USBtoUART /dev/cu.usbserial-0001
None of these is the J-Link. If I run lsusb I can see it:
$ lsusb
Bus 020 Device 002: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x UART Bridge / myAVR mySmartUSB light
Bus 020 Device 003: ID 1366:0101 SEGGER J-Link ARM
I have installed the "J-Link Software and Documentation Pack" downloaded from Segger. I have checked the Mac "Security and privacy" settings and it does not report that it blocked any drivers or programs from being installed or run.
On the J-Link, the green LED is on, with a very brief flash about twice per second.
I'm sure I have a piece missing, and would appreciate some help.
UPDATE: I have been following instructions here:
OpenOCD Instructions
It all works until I get to step 6, and I follow these instructions:
Serial driver instructions
The problem is, a path for the driver never shows up, as I described above. I don't think I can run OpenOCD if I can't make it talk to my J-link.
When I run openocd-esp32, I get (full paste from openocd-esp32 output is below):
Error: No J-Link device found.
The contents of esp32-wroom-32.cfg is:
echo "WARNING: boards/esp-wroom-32.cfg is deprecated, and may be removed in a future release."

After doing the above I now get a different error message when running openocd-esp32 (perhaps because of the J-Link FW upgrade?). Initially it complained that there was not an adapter speed set, so I modified interface/jlink.cfg and added:
adapter_khz 3000
I now get a different error:
Error: JTAG scan chain interrogation failed: all ones
Which I have been Googling, and which could mean a bad board or still another configuration issue. There is no SD card in the SD card socket and no other SPI devices on the board, although the ESP32-WROVER-32U has SPI flash on it.
Here is the complete output from openocd-esp32:

Success! This circuit used the Segger 10 pin needle connector. On that connector pin 1 is VTREF and on my board it was left floating, when it should have been connected to V3.3. I connected it and:

I would suggest to validate your setup step by step - I personally do not like big bang integrations.
Verify that your the Segger software can see your JLink probe - the good thing is that lsusb can see it. JLink Commander should provide some useful information.
Launch openocd without any executable-related arguments: openocd -f interface/jlink.cfg -f board/esp-wroom-32.cfg
Verify that basic commands are working, i.e. resetting the CPU, displaying registers, reading/writing memory.
If you you are still experimenting issues, double-check your wiring - see here for more information.

Intel Media Server Studio on CentOS7.2

I am trying to install and configure Intel Media Server Studio on a CentOS7.2 Machine with integrated VGA Graphics Card.
For validation of Successful installation(example), Metrics Monitor sample program fails with error code 1.
Command: ./_bin/metrics_monitor
ERROR: Failed to subscribe for metrics, error code 1
Test programs are also getting crashed, below are the machine specification:-
Processor: Intel(R) Core(TM) i7-3720QM CPU # 2.60GHz
(Intel Quick-Sync supported)
Graphics: Intel Corporation 3rd Gen Core processor Graphics Controller
(lspci | grep VGA)
I am following this to install and configure. I have verified pre-requisite for this installation out of which below is not matching:
vainfo | grep -v 'unknown'
Output on my machine:
libva info: VA-API version 0.99.0
libva info: va_getDriverName() returns 0
libva info: User requested driver 'iHD'
libva info: Trying to open /opt/intel/mediasdk/lib64/iHD_drv_video.so
libva info: Found init function __vaDriverInit_0_32
libva info: va_openDriver() returns 0
Can anybody tell what is wrong with the installation? as metric_monitor should give gpu usage.
