Hi Michel ! While your two previous patches apply just fine, this one doesn't, the uninorth_insert_memory() function seems to be slightly different upstream. Does this depend on some separate yet unapplied patches ? I'm putting 1/3 and 2/3 into my -test branch and they should hit my -next branch in a couple of days. Or do you prefer us to merge that via Dave ? The thing is, stuff in -powerpc is much more likely to get some amount of testing on actual ppc hardware than stuff in random other trees :-) Cheers, Ben. > drivers/char/agp/uninorth-agp.c | 64 > +++++++-------------------------------- > 1 files changed, 11 insertions(+), 53 deletions(-) > > diff --git a/drivers/char/agp/uninorth-agp.c b/drivers/char/agp/uninorth-agp.c > index bc8b43a..75aa33a 100644 > --- a/drivers/char/agp/uninorth-agp.c > +++ b/drivers/char/agp/uninorth-agp.c > @@ -144,53 +144,7 @@ static int uninorth_configure(void) > return 0; > } > > -static int uninorth_insert_memory(struct agp_memory *mem, off_t pg_start, > - int type) > -{ > - int i, j, num_entries; > - void *temp; > - int mask_type; > - > - if (type != mem->type) > - return -EINVAL; > - > - mask_type = agp_bridge->driver->agp_type_to_mask_type(agp_bridge, type); > - if (mask_type != 0) { > - /* We know nothing of memory types */ > - return -EINVAL; > - } > - > - if (mem->page_count == 0) > - return 0; > - > - temp = agp_bridge->current_size; > - num_entries = A_SIZE_32(temp)->num_entries; > - > - if ((pg_start + mem->page_count) > num_entries) > - return -EINVAL; > - > - j = pg_start; > - > - while (j < (pg_start + mem->page_count)) { > - if (agp_bridge->gatt_table[j]) > - return -EBUSY; > - j++; > - } > - > - for (i = 0, j = pg_start; i < mem->page_count; i++, j++) { > - agp_bridge->gatt_table[j] = > - cpu_to_le32((page_to_phys(mem->pages[i]) & > 0xFFFFF000UL) | 0x1UL); > - flush_dcache_range((unsigned > long)__va(page_to_phys(mem->pages[i])), > - (unsigned > long)__va(page_to_phys(mem->pages[i]))+0x1000); > - } > - (void)in_le32((volatile u32*)&agp_bridge->gatt_table[pg_start]); > - mb(); > - > - uninorth_tlbflush(mem); > - return 0; > -} > - > -static int u3_insert_memory(struct agp_memory *mem, off_t pg_start, int type) > +static int uninorth_insert_memory(struct agp_memory *mem, off_t pg_start, > int type) > { > int i, num_entries; > void *temp; > @@ -219,14 +173,18 @@ static int u3_insert_memory(struct agp_memory *mem, > off_t pg_start, int type) > for (i = 0; i < mem->page_count; ++i) { > if (gp[i]) { > dev_info(&agp_bridge->dev->dev, > - "u3_insert_memory: entry 0x%x occupied (%x)\n", > + "uninorth_insert_memory: entry 0x%x occupied > (%x)\n", > i, gp[i]); > return -EBUSY; > } > } > > for (i = 0; i < mem->page_count; i++) { > - gp[i] = (page_to_phys(mem->pages[i]) >> PAGE_SHIFT) | > 0x80000000UL; > + if (is_u3) > + gp[i] = (page_to_phys(mem->pages[i]) >> PAGE_SHIFT) | > 0x80000000UL; > + else > + gp[i] = cpu_to_le32((page_to_phys(mem->pages[i]) & > 0xFFFFF000UL) | > + 0x1UL); > flush_dcache_range((unsigned > long)__va(page_to_phys(mem->pages[i])), > (unsigned > long)__va(page_to_phys(mem->pages[i]))+0x1000); > } > @@ -236,7 +194,7 @@ static int u3_insert_memory(struct agp_memory *mem, off_t > pg_start, int type) > return 0; > } > > -int u3_remove_memory(struct agp_memory *mem, off_t pg_start, int type) > +int uninorth_remove_memory(struct agp_memory *mem, off_t pg_start, int type) > { > size_t i; > u32 *gp; > @@ -551,7 +509,7 @@ const struct agp_bridge_driver uninorth_agp_driver = { > .create_gatt_table = uninorth_create_gatt_table, > .free_gatt_table = uninorth_free_gatt_table, > .insert_memory = uninorth_insert_memory, > - .remove_memory = agp_generic_remove_memory, > + .remove_memory = uninorth_remove_memory, > .alloc_by_type = agp_generic_alloc_by_type, > .free_by_type = agp_generic_free_by_type, > .agp_alloc_page = agp_generic_alloc_page, > @@ -577,8 +535,8 @@ const struct agp_bridge_driver u3_agp_driver = { > .agp_enable = uninorth_agp_enable, > .create_gatt_table = uninorth_create_gatt_table, > .free_gatt_table = uninorth_free_gatt_table, > - .insert_memory = u3_insert_memory, > - .remove_memory = u3_remove_memory, > + .insert_memory = uninorth_insert_memory, > + .remove_memory = uninorth_remove_memory, > .alloc_by_type = agp_generic_alloc_by_type, > .free_by_type = agp_generic_free_by_type, > .agp_alloc_page = agp_generic_alloc_page, > -- > 1.6.3.3 > > _______________________________________________ > Linuxppc-dev mailing list > Linuxppc-dev@lists.ozlabs.org > https://lists.ozlabs.org/listinfo/linuxppc-dev _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
