At least some USB drives with a write protect switch (e.g. Netac U335)
could report "MEDIUM NOT PRESENT" for a while if a write protection is
enabled. Instead of stopping the initialization attempts immediately,
stop only after getting this report for 3 times, to ensure the
successful initialization of such a "broken hardware".

This series implements support for SMBIOS 3.0 entry points in
SeaBIOS.
The main advantage of SMBIOS 3.0 entry points is the higher limit
for total table size. The SMBIOS 2.1 64435 bytes limit can be
easily hit in QEMU if creating virtual machines with more than
720 VCPUs.
Eduardo Habkost (19):
biostables: copy_fseg_table() function
util.h: Delete unused get_smbios_entry_point() prototype
smbios: Rename code specific for SMBIOS 2.1 entry points
smbios: Generic smbios_next() function
smbios: smbios_get_tables() function
smbios: Use smbios_get_tables()/smbios_next() at display_uuid()
smbios: smbios_major_version()/smbios_minor_version() helpers
tpm: Use smbios_get_tables()
csm: Don't check SMBios21Addr before calling copy_smbios_21()
smbios: Make SMBios21Addr variable static
smbios: Use smbios_next() at smbios_romfile_setup()
smbios: Extract SMBIOS table building code to separate function
smbios: Make smbios_build_tables() more generic
smbios: smbios_21_setup_entry_point() function
smbios: Make some smbios_build_tables() arguments optional
smbios: Make smbios_build_tables() ready for 64-bit tables
smbios: copy_smbios_30() function
smbios: Support SMBIOS 3.0 entry point at copy_table()
smbios: Support SMBIOS 3.0 entry point at smbios_romfile_setup()

Hi,
The Open Source Firmware, BMC and Bootloader devroom will take place
on Sunday, 7th February 2021 at FOSDEM, virtual.
Call for Participation
----------------------
We are opening the call for participation to our devroom, with the deadline
for talk proposals set to Sunday, 20th December 2020 23:59:59 UTC.
Devroom Scope
-------------
The devroom will focus on various topics related to the open source
firmware,
BMC and bootloaders including security issues. It will help to get together
all interested people in one place, present and discuss current developments
and issues haunting the community. Additionally, it will foster awareness
among attendees about pre-OS topics.
Possible topics: GRUB, TrustedGRUB, iPXE, TrenchBoot, coreboot, LinuxBoot,
SeaBIOS, UEFI, OVMF, TianoCore, hostboot, IPMI, OpenBMC, u-bmc, TPM,
attestation, security of firmware, BMC, bootloaders and related topics and
technologies.
Ideal submissions are actionable and opinionated. Submissions may be in the
form of 25 or 45 minutes talks, panel sessions or round-table discussions.
Dates

Since the FOSDEM21 is going virtual, the talks will be prerecorded. We
will be
streaming the recordings and performing live Q&A of the Open Source
Firmware,
BMC and Bootloader devroom. Presenting at FOSDEM implies permission to
record
your session and distribute the recording afterwards. All videos will be
made
available under the standard FOSDEM content license (CC-BY).
If you have any questions, feel free to contact the devroom organizers:
Daniel Kiper (daniel.kiper at oracle.com) and
Michał Żygowski (michal.zygowski at 3mdeb.com).
