…g it to be different parse_bw() doesn't bother checking the bounds it is given if the resource is in use by mba_sc. This is because the values parsed from user-space are not the same as those the control should take. To make this disparity easier to work with, a second different copy of the schema format is needed, which would need a version of resctrl_get_default_ctrl(). This would let the resctrl change the schema format presented to user-space, provided it converts it to match what the architecture code expects. Add a second schema format for use with mba_sc. The membw properties are copied and the schema version is used. When mba_sc is enabled the schema copy of these properties is modified.

Resctrl allows the architecture code to specify the schema format for a control. Controls can either take a bitmap, or some kind of number. If user-space doesn't know what a control is by its name, it could be told the schema format. 'Some kind of number' isn't useful as the difference between a percentage and a value in MB/s affects how these would be programmed, even if resctrl's parsing code doesn't need to care. Add the types resctrl already has in addition to 'range'. This allows architectures to move over before 'range' is removed. These new schema formats are parsed the same, but will additionally affect which files are visible. Schema formats with a double underscore should not be considered portable between architectures, and are likely to be described to user-space as 'platform defined'. AMDs MBA resource is configured with an absolute bandwidth measured in multiples of one eighth of a GB per second. resctrl needs to be aware of this platform defined format to ensure the existing 'MB' files continue to be shown.

Resctrl specifies the schema format for MB and SMBA in rdt_resources_all[]. Intel platforms take a percentage for MB, AMD platforms take an absolute value which isn't MB/s. Currently these are both treated as a 'range'. Adding support for additional types of control shows that user-space needs to be told what the control formats are. Today users of resctrl must already know if their platform is Intel or AMD to know how the MB resource will behave. The MPAM support exposes new control types that take a 'percentage'. The Intel MB resource is also configured by a percentage, so should be able to expose this to user-space. Remove the static configuration for schema_fmt in rdt_resources_all[] and specify it with the other control properties in __get_mem_config_intel() or __get_mem_config_amd().

…entage MPAMs bandwidth controls are both exposed to resctrl as if they take a percentage. Update the schema format so that user-space can be told this is a perentage, and files that describe this control format are exposed. (e.g. min_percent) Existing variation in this area is covered by requiring user-space to know if it is running on an Intel or AMD platform. Exposing the schema format directly will avoid modifying user-space to know it is running on an MPAM or RISCV platform. MPAM can also expose bitmap controls for memory bandwidth, which may become important for use-cases in the future. These are currently converted to a percentage to fit the existing definition of the MB resource.

Resctrl previously had a 'range' schema format that took some kind of number. This has since been split into percentage, MB/s and an AMD platform specific scheme. As range is no longer used, remove it. The last user is mba_sc which should be described as taking MB/s.

…tmap controls MPAM has cache capacity controls that effectively take a percentage. Resctrl supports percentages, but the collection of files that are exposed to describe this control belong to the MB resource. To find the minimum granularity of the percentage cache capacity controls, user-space is expected to rad the banwdidth_gran file, and know this has nothing to do with bandwidth. The only problem here is the name of the file. Add duplicates of these properties with percentage and bitmap in the name. These will be exposed based on the schema format. The existing files must remain tied to the specific resources so that they remain visible to user-space. Using the same helpers ensures the values will always be the same regardless of the file used. These files are not exposed until the new RFTYPE schema flags are set on a resource 'fflags'.

If more schemas are added to resctrl, user-space needs to know how to configure them. To allow user-space to configure schema it doesn't know about, it would be helpful to tell user-space the format, e.g. percentage. Add a file under info that describes the schema format. Percentages and 'mbps' are implicitly decimal, bitmaps are expected to be in hex.

MPAM can have both cache portion and cache capacity controls on any cache that supports MPAM. Cache portion bitmaps can be exposed via resctrl if they are implemented on L2 or L3. The cache capacity controls can not be used to isolate portions, which is in implicit in the L2 or L3 bitmap provided by user-space. These controls need to be configured with something more like a percentage. Add the resource enum entries for these two resources. No additional resctrl code is needed because the architecture code will specify this resource takes a 'percentage', re-using the support previously used only for the MB resource.
