Convert physical address to text unit-string. Convert phys.lo ... phys-high, the numerical representation, to unit-string, the text string representation of a physical address within the address space defined by this device node. The number of cells in the list phys.lo ... phys.hi is determined by the value of the #address-cells property of this node.
This function is for devices with #address-cells == 4 Signed-off-by: Eric Snowberg <[email protected]> --- grub-core/kern/ieee1275/ieee1275.c | 46 ++++++++++++++++++++++++++++++++++++ include/grub/ieee1275/ieee1275.h | 7 +++++ 2 files changed, 53 insertions(+), 0 deletions(-) diff --git a/grub-core/kern/ieee1275/ieee1275.c b/grub-core/kern/ieee1275/ieee1275.c index 4617b36..7aef624 100644 --- a/grub-core/kern/ieee1275/ieee1275.c +++ b/grub-core/kern/ieee1275/ieee1275.c @@ -19,6 +19,7 @@ #include <grub/ieee1275/ieee1275.h> #include <grub/types.h> +#include <grub/misc.h> #define IEEE1275_PHANDLE_INVALID ((grub_ieee1275_cell_t) -1) #define IEEE1275_IHANDLE_INVALID ((grub_ieee1275_cell_t) 0) @@ -523,6 +524,51 @@ grub_ieee1275_decode_unit4 (grub_ieee1275_ihandle_t ihandle, return 0; } +char * +grub_ieee1275_encode_uint4 (grub_ieee1275_ihandle_t ihandle, + grub_uint32_t phy_lo, grub_uint32_t phy_hi, + grub_uint32_t lun_lo, grub_uint32_t lun_hi, + grub_size_t *size) +{ + char *addr; + struct encode_args + { + struct grub_ieee1275_common_hdr common; + grub_ieee1275_cell_t method; + grub_ieee1275_cell_t ihandle; + grub_ieee1275_cell_t tgt_h; + grub_ieee1275_cell_t tgt_l; + grub_ieee1275_cell_t lun_h; + grub_ieee1275_cell_t lun_l; + grub_ieee1275_cell_t catch_result; + grub_ieee1275_cell_t size; + grub_ieee1275_cell_t addr; + } + args; + + INIT_IEEE1275_COMMON (&args.common, "call-method", 6, 3); + args.method = (grub_ieee1275_cell_t) "encode-unit"; + args.ihandle = ihandle; + + args.tgt_l = phy_lo; + args.tgt_h = phy_hi; + args.lun_l = lun_lo; + args.lun_h = lun_hi; + args.catch_result = 1; + + if ((IEEE1275_CALL_ENTRY_FN (&args) == -1) || (args.catch_result)) + { + grub_error (GRUB_ERR_OUT_OF_RANGE, "encode-unit failed\n"); + return 0; + } + + addr = (void *)args.addr; + *size = args.size; + addr = grub_strdup ((char *)args.addr); + return addr; +} + + int grub_ieee1275_claim (grub_addr_t addr, grub_size_t size, unsigned int align, diff --git a/include/grub/ieee1275/ieee1275.h b/include/grub/ieee1275/ieee1275.h index b1940c2..5404ed6 100644 --- a/include/grub/ieee1275/ieee1275.h +++ b/include/grub/ieee1275/ieee1275.h @@ -218,6 +218,13 @@ int EXPORT_FUNC(grub_ieee1275_decode_unit4) (grub_ieee1275_ihandle_t ihandle, grub_uint32_t *lun_lo, grub_uint32_t *lun_hi); +char *EXPORT_FUNC(grub_ieee1275_encode_uint4) (grub_ieee1275_ihandle_t ihandle, + grub_uint32_t phy_lo, + grub_uint32_t phy_hi, + grub_uint32_t lun_lo, + grub_uint32_t lun_hi, + grub_size_t *size); + grub_err_t EXPORT_FUNC(grub_claimmap) (grub_addr_t addr, grub_size_t size); -- 1.7.1 _______________________________________________ Grub-devel mailing list [email protected] https://lists.gnu.org/mailman/listinfo/grub-devel
