Antoine Tenart says: ==================== net: phy: phylink: ensure the carrier is off when starting phylink Following the discussion we had regarding the phylink issue related to the carrier link state not being off when starting phylink, I sent a fix patch a few days ago for the PPv2 driver: https://lkml.org/lkml/2018/9/14/633 The idea was to send a patch which could go to the stable branches, but a better solution would be to directly call netif_carrier_off() from within phylink_start(). This is the aim of this series. ==================== Signed-off-by:

This patch removes the explicit call to netif_carrier_off() in mvneta_open() as this is already handled in phylink_start(). Signed-off-by:

This patch removes the explicit call to netif_carrier_off() in PPv2's open() path, as this is now handled in phylink_start(). Signed-off-by:
-
Antoine Tenart authored
Phylink made an assumption about the carrier state being down when calling phylink_start(). If this assumption isn't satisfied, the internal phylink state could misbehave and a net device could end up not being functional. This patch fixes this by explicitly calling netif_carrier_off() in phylink_start(). Signed-off-by:

Antoine Tenart says: ==================== net: mvpp2: improve the interrupt usage This series aims to improve the interrupts descriptions and usage in the Marvell PPv2 driver. - Before the series interrupts were named after their s/w usage, which in fact can be configured. The series rename all those interrupts and add a description of the ones left over. - In PPv2 the interrupts are mapped to vectors. Those vectors were directly mapped to a given CPU, and per-cpu accesses were done. While this worked on our cases, the registers accesses mapped to the vectors are not actually linked to a given CPU. They instead are linked to what is called a "s/w thread". The series modify this so that the s/w threads are used instead of the CPU numbers, by adding an indirection. This means we now can have systems with more CPUs than s/w threads. This is based on today's net-next, and was tested on various boards using both versions of the PPv2 engine. Two more patches will be coming, to update the device trees describing a PPv2 engine. The patches are ready, but will go through a different tree. I'll send them once this series will be accepted. This is not an issue as the PPv2 driver keeps the dt bindings backward compatibility. ==================== Signed-off-by: -

As the mvpp2_percpu_read/write/... functions aren't really per-cpu but per s/w thread, rename them to include 'thread' instead of 'percpu'. This is a cosmetic patch. Signed-off-by:

The Marvell PPv2 network controller has 9 internal threads. The driver works fine when there are less CPUs available than threads. This isn't true if more CPUs are available. As this is a valid use case, handle this particular case. Signed-off-by:

This patch maps all uses of the CPU to threads. All this_cpu calls are replaced, and all smp_processor_id() calls are wrapped into the indirection. Signed-off-by:

Updates the PPv2 driver so that all CPU variables are unsigned, as it makes no sense to have a negative CPU number. This patch is cosmetic. Signed-off-by:

The Marvell PPv2.2 engine only has 8 Rx queues per CPU, while PPv2.1 has 16 of them. This patch updates the code so that the Rx queues mask width is selected given the version of the network controller used. Signed-off-by:
-
Antoine Tenart authored
This patch updates the probing function so that the queue mode isn't updated while probing, as the driver would silently end up using a configuration not wanted by the user. The patch adds an extra check to validate the chosen queue mode instead, and the driver will fail to probe if the configuration is invalid. Signed-off-by:

Antoine Tenart authored
This patch renames the IRQs in the Marvell PPv2 driver as their current names match the way they are used in software. But this will change in the future, and those IRQs have nothing to do with Rx/Tx interrupts (this can be configured). The new binding also describe more interrupts as some where left out. The old binding support is kept for backward compatibility. Signed-off-by:

This patch sets the number of s/w threads to 9, its maximum value, instead of 8. This is not a fix as only 4 of the s/w threads were used so far, but more could be used in the future. Signed-off-by:

Heiner Kallweit says: ==================== net: phy: make phy_stop() synchronous There have been few not that successful attempts in the past to make phy_stop() a synchronous call instead of just changing the state. Patch 1 of this series addresses an issue which prevented this change. At least for me it works fine now. Would appreciate if Geert could re-test as well that suspend doesn't throw an error. ==================== Signed-off-by: -
Heiner Kallweit authored
phy_stop() may be called e.g. when suspending, therefore all needed actions should be performed synchronously. Therefore add a synchronous call to the state machine. Signed-off-by:

When bringing down the netdevice (incl. detaching it) and calling netif_carrier_off directly or indirectly the latter triggers an asynchronous linkwatch event. This linkwatch event eventually may fail to access chip registers in the ndo_get_stats/ndo_get_stats64 callback because the device isn't accessible any longer, see call trace in [0]. To prevent this scenario don't check for IFF_UP only, but also make sure that the netdevice is present. [0] https://lists.openwall.net/netdev/2018/03/15/62Signed-off-by:
