The hardware descriptors have big endian (BE) format. Provide proper endianness handling for the remaining descriptor fields, to ensure they are correctly accessed by non-BE CPUs too. Signed-off-by:

There are multiple occurences of both contextB and context_b in different h/w descriptors, referring to the same descriptor field known as "Context B". Stick with the "context_b" naming, for obvious reasons including consistency (see also context_a). Signed-off-by:

Preventively mask every access to the 'fqid' h/w field, since it is defined as a 24-bit field, for every h/w descriptor. Add generic accessors for this field to ensure correct access. Signed-off-by:

1. qm_mcc_querywq layout not used for now, so drop it; 2. queryfq, queryfq_np and alterfq are used only for accesses to the 'fqid' field, so replace these with a generic 'fq' layout. As a consequence, 'querycgr' turns into 'cgr' following the same reasoning above and for consistent naming. Signed-off-by:

Replace dummy platform device hack with a reference to a portal's platform device, in order to dma map the test frame for this small unit test. The 2 qman symbols need to be exported because this self test is a kernel module. Signed-off-by:
-
Claudiu Manoil authored
The qman portals are platform devices themselves, so they should handle dma mappings. Creating a dummy platform device in order to support dma mapping operations is not justified (and not portable). Instead, do the mapping against the first portal that has been initialised. Signed-off-by:

This function must only return the truth value of whether two frame descriptors are different or not. It does NOT have to compute some obscure difference between fd fields and return it as an int, making sparse complain about type conversions in the process. Signed-off-by:

Use the proper accessor to get the FD address. Accessing the internal field "addr_lo" directly is not portable and error prone. Signed-off-by:

qman_query_fq*() may return other error codes apart from -ERANGE, in which cases the error handling done by the resource cleanup callers would be wrong. The patch fixes the handling of those cases, and cleans up related code inside the resource cleanup & release handlers (i.e. replace hardcoded fqid value with corresponding define). Signed-off-by:

Version 3.00 of the ISA states that the PATS (partition table size) field of the PTCR (partition table control register) and the PRTS (process table size) field of the partition table entry must both be less than or equal to 24. However the actual size of the partition and process tables is equal to 2 to the power of 12 plus the PATS and PRTS fields, respectively. This means that the max allowable size of each of these tables is 2^36 or 64GB for both. Thus when checking the size shift for each we should be checking for values of greater than 36 instead of the current check for shifts larger than 24 and 23. Fixes: 2bfd65e4Signed-off-by:

Useful to be able to dump the kernel hash page table to check which pages are hashed along with their sizes and other details. Add a debugfs file to check the hash page table. If radix is enabled (and so there is no hash page table) then this file doesn't exist. To use this the PPC_PTDUMP config option must be selected. Signed-off-by:
