SDK v1.1 Software Errata

Reference	Description	Workaround
ENGR148155	SRIO functionality is not supported under Hypervisor.	None.
ENGR151644	Attempting to execute valgrind (3.6.1) will result in a segmentation fault.	None.
ENGR155098	Under high-load, netperf TCP tests may cause a memory corruption after several hours of running on P4080 rev2. The issue occurs in the Linux TCP stack and contaminates the DPAA-Ethernet driver. The problem has not been observed with netperf UDP or in other test environments	None.
ENGR155760	Linux IPFwd performance has degraded slightly compared to SDK v1.0 on P4080, P3041 and P5020. The amount of degradation varies across supported processors by 9-15%.	1) With SDK v1.1, no workaround exists. Patches may be provided post release as they become available. 2) Continue to use SDK v1.0 until IPFwd performance is resolved.
ENGR156088	SATA PMP card is not supported P2041RDB, P5020DS, P3041DS using the native SATA port.	Use a PCIe-SATA card for PMP on P2041, P5020, P3041.
ENGR156134	On P5020, RAID6 with the hardware accelerator Is not supported.	1) Use software based RAID6 2) Use RAID5
ENGR156155	USDPAA requires the "fsl_usdpaa_shmem" device to be compiled into the kernel, which causes a contiguous memory allocation to occur early during kernel boot. This driver does not support kernels operating with a non-zero base-address, which means it is not safe when operating as a guest under KVM. (So USDPAA cannot be used in a KVM guest.) In particular, for a kernel to be usable as a KVM guest, it must be compiled without CONFIG_FSL_USDPAA_SHMEM defined.	When building a kernel that needs to be usable as a KVM guest (and so USDPAA support will be unavailable), disable the USDPAA "shmem" device in the kernel build configuration. If editing the ".config" file directly, ensure that CONFIG_FSL_USDPAA_SHMEM is undefined. If using the kernel "menuconfig" interface, go into "Device Drivers" -> "Misc devices" and disable the option marked "NXP^® USDPAA shared memory driver".
ENGR158331	Linux IPSec performance has significantly degraded due to several changes in the Linux network stack.	1) With SDK v1.1, no workaround exists. NXP is actively working to resolve. Patches will be provided post release as they become available. 2) Continue to use SDK v1.0 until IPSec performance is resolved.
ENGR158382	The glibc packaged with gcc 4.5.2 included in this release has an issue which can result in the following glibc error: "Inconsistency detected by ld.so: dl-deps.c: 622: _dl_map_object_deps: Assertion `nlist > 1' failed!" More information on this topic: http://sourceware.org/bugzilla/show_bug.cgi?id=12454	None. The fix requires an update from CodeSourcery.
ENGR158626	The 64-bit Linux kernel does not support External Proxy (CoreInt) Interrupt mode. Without this support the interrupts are always working in legacy mode which is incompatible with 64-bit Hypervisor. 64-bit Hypervisor does not support mixing virtual interrupts and physical interrupts. Without External Proxy support external interrupts will not work and some drivers (e.g. MMC, PCIe, DPAA networking) are affected.	Use 32-bit Linux with either 32-bit or 64-bit Hypervisor.
ENGR160042	USDPAA RMan application cannot support type 11 protocol when packets are sent continuously.	1) Use type 9 protocol for continuous packet transfer. 2) Use type 11 protocol only with single packet.
ENGR160219	On P1023, the FMan module must receive only frame buffers that are 16-byte aligned. The DPAA ehternet driver may in some circumstances populate the BMan buffer pool used by FMan ports with unaligned buffers.	A workaround for this issue is available in the form of a patch: diff --git a/drivers/net/dpa/dpaa_eth.c b/drivers/net/dpa/dpaa_eth.c index bf2efff..7deb3ad 100644 --- a/drivers/net/dpa/dpaa_eth.c +++ b/drivers/net/dpa/dpaa_eth.c @@ -1319,8 +1319,17 @@ static int __hot dpa_tx(struct sk_buff skb, struct net_device net_dev) fd.length20 = skb->len; fd.offset = DPA_BP_HEAD; /* This is now guaranteed / + / + * Check if skb can be recycled / buffer can be readded to the bman pool + * The following conditions must be met: + * - skb not cloned, not shared + * - buffer size is large enough to accomodate a MTU-sized frame + * - there's enough room in the buffer pool + * - address of the recycled buffer is 16 byte aligned (as per DPAA RM) + / if (likely(skb_is_recycleable(skb, dpa_bp->size + pad) - && (percpu_priv->dpa_bp_count + 1 <= dpa_bp->count))) { + && (*percpu_priv->dpa_bp_count + 1 <= dpa_bp->count) + && (IS_ALIGNED((unsigned long)skbh, 16)))) { fd.cmd \|= FM_FD_CMD_FCO; fd.bpid = dpa_bp->bpid; skb_recycle(skb);
ENGR160307	At the time of this release, Secure Boot could not be verified on P2041 and P3060. However, there is no known issues would prevent Secure Boot from functioning on these targets.	N/A
ENGR160619	On P3060, MAC-less Ethernet between 2 Linux partitions on Hypervisor is not supported.	None.
ENGR160789	For P3060, when selecting the PME kernel driver option to enable scan test at kernel boot time, the PME database that is created fails. Issue is specific to processors with PME HW ver. 2.2 (e.g. P3060).	Don't enable the PME driver option to enable scan test.
