Subject: [PATCH] MIPS: lantiq: enable all hardware interrupts on second VPE
|
|
||||||
|
|
||||||
This patch is needed to handle interrupts by the second VPE on the Lantiq
|
|
||||||
ARX100, xRX200, xRX300 and xRX330 SoCs. Switching some ICU interrupts to
|
|
||||||
the second VPE results in a hang. Currently, the vsmp_init_secondary()
|
|
||||||
function is responsible for enabling these interrupts. It only enables
|
|
||||||
Malta-specific interrupts (SW0, SW1, HW4 and HW5).
|
|
||||||
|
|
||||||
The MIPS core has 8 interrupts defined. On Lantiq SoCs, hardware
|
|
||||||
interrupts are wired to an ICU instance. Each VPE has an independent
|
|
||||||
instance of the ICU. The mapping of the ICU interrupts is shown below:
|
|
||||||
SW0(IP0) - IPI call,
|
|
||||||
SW1(IP1) - IPI resched,
|
|
||||||
HW0(IP2) - ICU 0-31,
|
|
||||||
HW1(IP3) - ICU 32-63,
|
|
||||||
HW2(IP4) - ICU 64-95,
|
|
||||||
HW3(IP5) - ICU 96-127,
|
|
||||||
HW4(IP6) - ICU 128-159,
|
|
||||||
HW5(IP7) - timer.
|
|
||||||
|
|
||||||
This patch enables all interrupt lines on the second VPE.
|
|
||||||
|
|
||||||
This problem affects multithreaded SoCs with a custom interrupt controller.
|
|
||||||
SOCs with 1004Kc core and newer use the MIPS GIC. At this point, I am aware
|
|
||||||
that the Realtek RTL839x and RTL930x SoCs may need a similar fix. In the
|
|
||||||
future, this may be replaced with some generic solution.
|
|
||||||
|
|
||||||
Tested on Lantiq xRX200.

Subject: [PATCH] MIPS: lantiq: register smp_ops on non-smp platforms
|
|
||||||
|
|
||||||
Lantiq uses a common kernel config for devices with 24Kc and 34Kc cores.
|
|
||||||
The changes made previously to add support for interrupts on all cores
|
|
||||||
work on 24Kc platforms with SMP disabled and 34Kc platforms with SMP
|
|
||||||
enabled. This patch fixes boot issues on Danube (single core 24Kc) with
|
|
||||||
SMP enabled.

Subject: [PATCH] net: lantiq: add support for jumbo frames
|
|
||||||
|
|
||||||
Add support for jumbo frames. Full support for jumbo frames requires
|
|
||||||
changes in the DSA switch driver (lantiq_gswip.c).
|
|
||||||
|
|
||||||
Tested on BT Hone Hub 5A.

Subject: [PATCH] net: lantiq_xrx200: increase buffer reservation
|
|
||||||
|
|
||||||
If the user sets a lower mtu on the CPU port than on the switch,
|
|
||||||
then DMA inserts a few more bytes into the buffer than expected.
|
|
||||||
In the worst case, it may exceed the size of the buffer. The
|
|
||||||
experiments showed that the buffer should be a multiple of the
|
|
||||||
burst length value. This patch rounds the length of the rx buffer
|
|
||||||
upwards and fixes this bug. The reservation of FCS space in the
|
|
||||||
buffer has been removed as PMAC strips the FCS.
|
|
||||||
|
|
||||||

Subject: [PATCH] net: lantiq_xrx200: add ingress SG DMA support
|
|
||||||
|
|
||||||
This patch adds support for scatter gather DMA. DMA in PMAC splits
|
|
||||||
the packet into several buffers when the MTU on the CPU port is
|
|
||||||
less than the MTU of the switch. The first buffer starts at an
|
|
||||||
offset of NET_IP_ALIGN. In subsequent buffers, dma ignores the
|
|
||||||
offset. Thanks to this patch, the user can still connect to the
|
|
||||||
device in such a situation. For normal configurations, the patch
|
|
||||||
has no effect on performance.

Subject: net: dsa: lantiq_gswip: enable jumbo frames on GSWIP
|
|
||||||
|
|
||||||
This enables non-standard MTUs on a per-port basis, with the overall
|
|
||||||
frame size set based on the CPU port.
|
|
||||||
|
|
||||||
When the MTU is not changed, this should have no effect.
|
|
||||||
|
|
||||||
Long packets crash the switch with MTUs of greater than 2526, so the
|
|
||||||
maximum is limited for now. Medium packets are sometimes dropped (e.g.
|
|
||||||
TCP over 2477, UDP over 2516-2519, ICMP over 2526), Hence an MTU value
|
|
||||||
of 2400 seems safe.

Subject: [PATCH 5/5] net: lantiq: configure the burst length in ethernet
|
|
||||||
drivers
|
|
||||||
|
|
||||||
Configure the burst length in Ethernet drivers. This improves
|
|
||||||
Ethernet performance by 58%. According to the vendor BSP,
|
|
||||||
8W burst length is supported by ar9 and newer SoCs.
|
|
||||||
|
|
||||||
The NAT benchmark results on xRX200 (Down/Up):
|
|
||||||
* 2W: 330 Mb/s
|
|
||||||
* 4W: 432 Mb/s 372 Mb/s
|
|
||||||
* 8W: 520 Mb/s 389 Mb/s
|
|
||||||
|
|
||||||
Tested on xRX200 and xRX330.

Subject: [PATCH 715/715] net: lantiq_xrx200: convert to build_skb
|
|
||||||
|
|
||||||
We can increase the efficiency of rx path by using buffers to receive
|
|
||||||
packets then build SKBs around them just before passing into the network
|
|
||||||
stack. In contrast, preallocating SKBs too early reduces CPU cache
|
|
||||||
efficiency.

Subject: net: lantiq_xrx200: fix use after free bug
|
|
||||||
|
|
||||||
The skb->len field is read after the packet is sent to the network
|
|
||||||
stack. In the meantime, skb can be freed. This patch fixes this bug.

xrx200_hw_receive() assumes build_skb() always works and goes straight

to skb_reserve(). However, build_skb() can fail under memory pressure.

Subject: [PATCH] net: lantiq_xrx200: fix lock under memory pressure
|
|
||||||
|
|
||||||
When the xrx200_hw_receive() function returns -ENOMEM, the NAPI poll
|
|
||||||
function immediately returns an error.
|
|
||||||
This is incorrect for two reasons:
|
|
||||||
* the function terminates without enabling interrupts or scheduling NAPI,
|
|
||||||
* the error code (-ENOMEM) is returned instead of the number of received
|
|
||||||
packets.
|
|
||||||
|
|
||||||
After the first memory allocation failure occurs, packet reception is
|
|
||||||
locked due to disabled interrupts from DMA..
