Hi,
This is an interesting topic for me so I would like to join the conversation.
I will be glad if I can be of any help here either in testing PSI, or
verifying some scenarios and observation.
I have some experience working with low memory embedded devices, like
RAM as low as 128MB,
Depending on how BIOS has marked the reserved region containing the 32KB
MCHBAR you can get warnings like:
resource sanity check: requesting [mem 0xfed1-0xfed1], which spans more
than reserved [mem 0xfed1-0xfed17fff]

When a resource is freed and has children, the childrens are
left without any hint that their parent is no more valid.
This caused at least one use-after-free in the xhci-hcd using
ext-caps driver when platform code released platform devices.
Fix this by setting child's parent to zero and warn.

commit 54648cf1ec2d7f4b6a71767799c45676a138ca24 upstream.
We find the memory use-after-free issue in __blk_drain_queue()
on the kernel 4.14. After read the latest kernel 4.18-rc6 we
think it has the same problem.
Memory is allocated for q->fq in the blk_init_allocated_queue().

The internal delays for the RGMII are configurable for both RX & TX. This
change adds support for configuring them via device-tree (or ACPI).

The ADIN1200 & ADIN1300 PHYs support EEE by using standard Clause 45 access
to access MMD registers for EEE.
The EEE register addresses (when using Clause 22) are available at
different addresses (than Clause 45), and since accessing these regs (via
Clause 22) needs a special mechanism, a
This change implements retrieving all the error counters from the PHY.
The PHY supports several error counters/stats. The `Mean Square Errors`
status values are only valie when a link is established, and shouldn't be
accumulated. These values characterize the quality of a signal.
The rest of the
The ADIN PHYs supports 4 types of reset:
1. The standard PHY reset via BMCR_RESET bit in MII_BMCR reg
2. Reset via GPIO
3. Reset via reg GeSftRst (0xff0c) & reload previous pin configs
4. Reset via reg GeSftRst (0xff0c) & request new pin configs
Resets 2 & 4 are almost identical, with the
Both ADIN1200 & ADIN1300 support Clause 45 access for some registers.
The Extended Management Interface (EMI) registers are accessible via both
Clause 45 (at register MDIO_MMD_VEND1) and using Clause 22.
However, the Clause 22 access for MMD regs differs from the standard one
defined by 802.3.
The ADIN1300 chip supports RGMII, RMII & MII modes. Default (if
unconfigured) is RGMII.
This change adds support for configuring these modes via the device
registers.
For RGMII with internal delays (modes RGMII_ID,RGMII_TXID, RGMII_RXID),
the default delay is 2 ns. This can be configurable and
The ADIN PHYs support automatic MDI/MDIX negotiation. By default this is
disabled, so this is enabled at `config_init`.
This is controlled via the PHY Control 1 register.
The supported modes are:
1. Manual MDI
2. Manual MDIX
3. Auto MDIX - prefer MDIX
4. Auto MDIX - prefer MDI

Down-speed auto-negotiation may not always be enabled, in which case the
PHY won't down-shift to 100 or 10 during auto-negotiation.

The ADIN PHYs support Energy Detect Powerdown mode, which puts the PHY into
