Thanks for calling this out. This was an intentional design decision to
break a circular dependency.
The charger driver is guaranteed to probe after the TCPC driver due to a
power supply dependency (the TCPC is a supplier of power for the Battery
Charger). However, the charger driver is also the regulator provider for
VBUS out (when Type-C goes into source mode).
Because of this, the regulator handle will not be available during the
TCPC driver's probe. If we tried to fetch it in max_tcpci_probe() and
returned -EPROBE_DEFER, it would create a probe deadlock, as the charger
would then never probe. Therefore, I made the decision to get the
regulator handle lazily and on-demand.
Thanks,
Amit

I think sashiko is over cautions here
(https://sashiko.dev/#/patchset/20260330161705.3349825-1-ryan.roberts@arm.com)
but it has a somewhat valid point from the perspective of
num_online_cpus() semantics. We have have num_online_cpus() == 1 while
having a secondary CPU just booted and with its MMU enabled. I don't
think we can have any asynchronous tasks running at that point to
trigger a spit though. Even async_init() is called after smp_init().
An option may be to attempt cpus_read_trylock() as this lock is taken by
_cpu_up(). If it fails, return -EBUSY, otherwise check num_online_cpus()
and unlock (and return -EBUSY if secondaries already started).
Another thing I couldn't get my head around - IIUC is_realm_world()
won't return true for map_mem() yet (if in a realm). Can we have realms
on hardware that does not support BBML2_NOABORT? We may not have
configuration with rodata_full set (it should be complementary to realm
support).
I'll add the patches to for-next/core to give them a bit of time in
-next but let's see next week if we ignore this (with an updated
comment) or we try to avoid the issue altogether.

Hmm, that "like everyone else" made me think - why not move this to
generic code and only the 1-2 platforms that need their own should
override it? Could we do the same with copy_page()?
Sorry, more work all of a sudden ;).

The custom clear_page() had the (very small) advantage that it can skip
the length/alignment checks as they are always page-size.

I assume the benchmarks ran on real hardware (had to ask, last time you
mentioned qemu ;)).

From: Jitendra Vegiraju <jitendra.vegiraju@broadcom.com>
This patchset adds basic PCI ethernet device driver support for Broadcom
BCM8958x Automotive Ethernet switch SoC devices.
This SoC device has PCIe ethernet MAC attached to an integrated ethernet
switch using XGMII interface. The PCIe ethernet controller is presented to
the Linux host as PCI network device.
Management of integrated ethernet switch on this SoC is not handled via
the PCIe interface.
The following block diagram gives an overview of the application.
+=================================+

| +--------------+ |
| | Ethernet | |
| | switch | |
| +--------------+ |
| || || || || |
+==========================================+
|| || || || More external interfaces
The MAC block on BCM8958x is based on Synopsis XGMAC 4.00a core. This
MAC IP introduces new DMA architecture called Hyper-DMA for virtualization
scalability.
Driver functionality specific to new MAC (DW25GMAC) is implemented in
new file dw25gmac.c.
v8->v9:
Patch1:
Merged patch1 and patch2 to avoid patchwork warning (Simon Horman)
Patch2:
Patch3 from v8.
Patch3:
Merged patch4 and patch5 from v8 (Russell King).
Addressed review comments from Russell King.
Removed redundant initialization of zero-initialized variables.
Allocate sequential interrupt vectors for per channel interrupts.
Remove device id based setup function in glue driver as currently
a single device id is supported.
Patch4:
Following the recent upstream patch, removed "depends on STMMAC_ETH"
statment in Kconfig.
v7->v8:
Addressed review comments from v7.
Patch2:
Add a helper function with common code for three setup functions
in dwxgmac2_core.c (Russell King).
Patch4:
Use stmmac_plat_dat_alloc() to allocate memory for
:plat_stmmacenet_data: (Russell King).
Changed few bool variable initialization to bool types in
dwxgmac_brcm_default_data().
Patch5:
Make use of plat->init, plat->exit handlers to cleanup
probe function error handling path (Russell King).
Use managed API to free irq vectors.
v6->v7:
Minor changes to v6 patchset adapting to recent changes net-next.
Patch1:
Make use of the core_type variable for MAC core identification.
Define enum value DWMAC_CORE_25GMAC and discard previous proposal to
add new variables in struct plat_stmmacenet_data.
Patch2:
Updated patch to latest net-next branch code base.
Patch3:
Modified hwif entry matching to use core_type DWMAC_CORE_25GMAC.
Patch4:
Adapted glue driver to match recent stmmac core changes.
Changed susped/resume functionality to use common framework.
https://lore.kernel.org/netdev/20260313222206.778760-1-jitendra.vegiraju@broadcom.com/
v5->v6:
Change summary to address comments/suggestions by Serge Semin.
Patch1:
Removed the complexity of hdma mapping in previous patch series and
use static DMA mapping.
Renamed plat_stmmacenet_data::snps_dev_id as dev_id and moved to
the beginning of the struct.
Patch2:
Added dw25gmac_get_hw_feature() for dw25gmac.
Use static one-to-one VDMA-TC-PDMA mapping.
Patch4:
Remove usage of plat_stmmacenet_data::msi_*_vec variables for
interrupt vector initialization.
Change phy_interface type to XGMII.
Cleanup unused macros.
https://lore.kernel.org/netdev/20241018205332.525595-1-jitendra.vegiraju@broadcom.com/
v4->v5:
Summary of changes in this patch series:
As suggested by Serge Semin, defined common setup function for dw25gmac.
To accommodate early adopter DW25GMAC used in BCM8958x device, provide
a mechanism to override snps_id and snps_dev_id used for driver entry
matching in hwif.c
Patch1:
Added plat_stmmacenet_data::snps_id,snps_dev_id fields - Serge Semin
Patch2:
Define common setup function for dw25gmac_setup() - Serge Semin
Support DW25GMAC IPs with varying VDMA/PDMA count - Abhishek Chauhan
Allocate and initialize hdma mapping configuration data dynamically
based on device's VDMA/PDMA feature capabilities in dw25gmac_setup().
Spelling errors in commit log, lower case 0x for hex -Amit Singh Tomar
Patch3:
Glue support in hwif.c for DW25GMAC in hwif.c - Serge Semin
Provide an option to override snps_id and snps_dev_id when the device
reports version info not conformant with driver's expectations as is
the case with BCM8958x device. - Serge Semin
Patch4:
Remove setup function in the glue driver - Serge Semin
Remove unnecessary calls pci_enable_device() and pci_set_master()
in dwxgmac_brcm_pci_resume() - Jakub Kicinski
Merge variable definitions to single line - Amit Singh Tomar
https://lore.kernel.org/netdev/20240904054815.1341712-1-jitendra.vegiraju@broadcom.com/
v3->v4:
Based on Serge's questions, received a confirmation from Synopsys that
the MAC IP is indeed the new 25GMAC design.
Renamed all references of XGMAC4 to 25GMAC.
The patch series is rearranged slightly as follows.
Patch1 (new): Define HDMA mapping data structure in kernel's stmmac.h

Add PCI ethernet driver support for Broadcom BCM8958x SoC devices used
in automotive applications.
This SoC device has PCIe ethernet MAC attached to an integrated ethernet
switch using XGMII interface. The PCIe ethernet controller is presented to
the Linux host as PCI network device.
The following block diagram gives an overview of the application.
+=================================+
| Host CPU/Linux |

| || XGMII |
| || |
| +--------------+ |
| | Ethernet | |
| | switch | |
| +--------------+ |
| || || || || |
+==========================================+
|| || || || More external interfaces
The MAC IP block on BCM8958x is based on Synopsis XGMAC 4.00a core. This
driver uses common dwxgmac2 code where applicable.
Driver functionality specific to this MAC is implemented in dw25gmac.c.
Management of integrated ethernet switch on this SoC is not handled via
the PCIe interface.
This SoC device has PCIe ethernet MAC directly attached to an integrated
ethernet switch using XGMII interface. Since device tree support is not
available on this platform, a software node is created to enable
fixed-link support using phylink driver.

* [PATCH net-next v9 1/4] net: stmmac: Add DW25GMAC support in stmmac core driver

In-Reply-To: <20260402213629.1996133-1-jitendra.vegiraju@broadcom.com>
From: Jitendra Vegiraju <jitendra.vegiraju@broadcom.com>
The DW25GMAC introduced a new DMA architecture called Hyper-DMA (HDMA) for
virtualization scalability. This is realized by decoupling physical DMA
channels(PDMA) from potentially large number of virtual DMA channels(VDMA).
The VDMAs provide software abstraction to driver that map to PDMAs for
frame transmission and reception.
Since 25GMAC is a derivative of XGMAC, majority of IP is common to both.
To add support for the HDMA in 25GMAC, a new instance of dma_ops,
dw25gmac400_dma_ops is introduced.
To support the current needs, a simple one-to-one mapping of dw25gmac's
logical VDMA (channel) to TC to PDMAs is used. Most of the other dma
operation functions in existing dwxgamc2_dma.c file are reused whereever
applicable.
Added setup function for DW25GMAC's stmmac_hwif_entry in stmmac core.

Hi Kevin,
I applied this one, but I noticed two problems:
There is no long form changelog text, please add
more information about what is in the branch in
the future. I've added a short paragraph while
applying.

Can you have a look to see if my intuition is right on these
