         * window (a.k.a. WID) is 1kB.
         * Summary:
         *    1kB WID x N WIDS = DPI page size
         *    DPI page size x N DPIs = PWM region size
         * Notes:
         * The size of the DPI page size must be in multiples of OSAL_PAGE_SIZE
         * in order to ensure that two applications won't share the same page.
         * It also must contain at least one WID per CPU to allow parallelism.
         * It also must be a power of 2, since it is stored as a bit shift.
         *
         * The DPI page size is stored in a register as 'dpi_bit_shift' so that
         * 0 is 4kB, 1 is 8kB and etc. Hence the minimum size is 4,096
