I only find something related to ACPI, which I don't understand whether 
is significant:

~$ sudo journalctl -k|grep -i firmware
Sep 17 21:14:48 alan kernel: ACPI: [Firmware Bug]: BIOS _OSI(Linux) 
query ignored
Sep 17 21:14:48 alan kernel: acpi PNP0A08:00: [Firmware Info]: MMCONFIG 
for domain 0000 [bus 00-9b] only partially covers this bridge

And then a strange error message, it doesn't find a .txt file:

Sep 17 21:14:50 alan kernel: brcmfmac 0000:03:00.0: firmware: 
direct-loading firmware brcm/brcmfmac43602-pcie.bin
Sep 17 21:14:50 alan kernel: brcmfmac 0000:03:00.0: firmware: failed to 
load brcm/brcmfmac43602-pcie.txt (-2)
Sep 17 21:14:50 alan kernel: brcmfmac 0000:03:00.0: Direct firmware load 
for brcm/brcmfmac43602-pcie.txt failed with error -2
[...]

brcm/brcmfmac43602-pcie.bin is the firmware for my Broadcom BCM43602 
wireless card, contained in package firmware-brcm80211. Without it the 
wifi network adapter didn't work, so I provided it during installation, 
and then that package was automatically installed. I don't understand 
what's that brcm/brcmfmac43602-pcie.txt file, it complained about it 
also during installation, but the wifi card works nevertheless.

So can I conclude that I wouldn't get any benefit by installing 
firmware-linux-nonfree? And what about intel-microcode that I've just 
installed? Can I expect some performance related benefit?
