A firmware error is triggered when configuring a 9k MTU on the PF after switching to switchdev mode and then using a vdpa device with larger (1k) rings: mlx5_cmd_out_err: CREATE_GENERAL_OBJECT(0xa00) op_mod(0xd) failed, status bad resource(0x5), syndrome (0xf6db90), err(-22) This is due to the fact that the hw VQ size parameters are computed based on the umem_1/2/3_buffer_param_a/b capabilities

From: Colin Ian King <colin.king at canonical.com> The memory allocation failure checking for in and out is currently checking if the pointers are valid rather than the contents of what they point to. Hence the null check on failed memory allocations is incorrect. Fix this by adding the missing indirection in the check. Also for the default case, just set the *in and *out to null as these

This patchset is pre-requisite to export and provision device config attributes and features for vdpa live migration, in a way backward and forward compatibility can be retained. The follow up work [1] will need to be built around the new feature provisioning uAPI, with which it's easier to formalize migration compatibility support at the driver level.

Dear R People: Hello! I'm putting together another RcmdrPlugin package and need to add a FORTRAN subroutine to speed things up a bit. I've never added compiled code to a package. Anyhow, I put my code into a /src directory. Here are the statements: * using log directory 'c:/R/R-2.11.1/bin/RcmdrPlugin.push.Rcheck' * using R version 2.11.1 (2010-05-31) * using session charset:
