Hi,
We tried to hot add more than 16 numbers of virtio-blk devices to pci bridge,
but found that only 16 of them are available in VM.
There are ‘no space’ error messages in dmesg:
[4.666106] pci :00:03.0: PCI bridge to [bus 01]
[4.666191] pci :00:03.0: bridge window [io 0x7
Instead of blacklisting all Broadwell processorsi for running a late
loading, only BDW-EP (signature 406f1) with the microcode version
less than 0x0b21 needs to be blacklisted.

Since the hwlock id 0 is valid for hardware spinlock core, but now id 0
is treated as one invalid value for regmap. Thus we should add one extra
flag for regmap config to indicate if a hardware spinlock should be used,
then id 0 can be valid for regmap to request.

This flag is only used to warn if CLKRUN_EN wasn't disabled on Braswell

Hello,
Commit 5e572cab92f0 ("tpm: Enable CLKRUN protocol for Braswell systems")
added logic in the TPM TIS driver to disable the Low Pin Count CLKRUN
signal during TPM transactions.
Unfortunately this breaks other devices that are attached to the LPC bus
like for example PS/2 mouse and keyboards.
The coding style says "use just one data declaration per line (no commas
for multiple data declarations)" so follow this convention.

Use more common function and variable names.
Use pdev instead of dev for platform device.
Use sp5100_tco_probe() instead of sp5100_tco_init() for the probe function.
Drop sp5100_tco_cleanup(); just move the code into sp5100_tco_remove().

Starting with Family 16h Models 30h-3Fh and Family 15h Models 60h-6Fh,
watchdog address space decoding has changed. The cutover point is already
identified in the i2c-piix2 driver, so use the same mechanism.

If the watchdog control register indicates that the watchdog hardware
is disabled even after we tried to enable it, there is no point to
instantiate the driver.

Convert to watchdog subsystem. As part of that rework, use devm functions
where possible, and replace almost all static variables with a dynamically
allocated data structure.

SP5100_IO_PM_INDEX_REG and SB800_IO_PM_INDEX_REG are used inconsistently
and define the same value. Just use SP5100_IO_PM_INDEX_REG throughout.
Do the same for SP5100_IO_PM_DATA_REG and SB800_IO_PM_DATA_REG.
Use helper functions to access the indexed registers.

The sp5100_tco watchdog driver does not really support recent AMD CPUs,
even though it claims to do so. On top of that, it doesn't use the
watchdog subsystem, and various other problems have crept in. Let's
clean it up for good.
The code was tested on AMD Ryzen 1700 with motherboards from MSI and

The Launch Enclave (LE) generates cryptographic launch tokens for user
enclaves. A launch token is used by EINIT to check whether the enclave
is authorized to launch or not. By having its own launch enclave, Linux
has full control of the enclave launch process.
LE is wrapped into a user space prox

Intel SGX is a set of CPU instructions that can be used by applications
