Greg:
For those of us who forget that when bits 21 and bit 31 in a hardware register exposed with debugfs, I should see 2149580800 when I cat it (vs 0x80200000), any objections to providing a hex output interface to the debugfs?
Since the input side already takes decimal & hex, I don't think this is a big change:
DEFINE_SIMPLE_ATTRIBUTE(fops_x16, debugfs_u16_get, debugfs_u16_set, "0x%04llx\n");
struct dentry *debugfs_create_x16(const char *name, mode_t mode, struct dentry *parent, u16 *value) { return debugfs_create_file(name, mode, parent, value, &fops_x16); }
DEFINE_SIMPLE_ATTRIBUTE(fops_x32, debugfs_u32_get, debugfs_u32_set, "0x%08llx\n");
struct dentry *debugfs_create_x32(const char *name, mode_t mode, struct dentry *parent, u32 *value) { return debugfs_create_file(name, mode, parent, value, &fops_x32); }
If this is OK - I will send a real patch.
