From afe02efb8fd75c49e73af047649dfe80d22fc2fd Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Josef=20S=C3=B6ntgen?= <josef.soentgen@genode-labs.com> Date: Tue, 22 Mar 2022 17:55:08 +0100 Subject: [PATCH] pc_usb_host: implement 'dma_pool_destroy' Encountered on the Fuji5 where for reasons currently unknown the first xHCI HC (0:0d.0) could not be initialize due to incomplete interupt informations. The other HCs appear to work fine (tested with a USB low-speed mouse). --- repos/pc/src/drivers/usb_host/pc/generated_dummies.c | 8 -------- repos/pc/src/drivers/usb_host/pc/lx_emul.c | 6 ++++++ 2 files changed, 6 insertions(+), 8 deletions(-) diff --git a/repos/pc/src/drivers/usb_host/pc/generated_dummies.c b/repos/pc/src/drivers/usb_host/pc/generated_dummies.c index 3bd20d3289..7655a71d4a 100644 --- a/repos/pc/src/drivers/usb_host/pc/generated_dummies.c +++ b/repos/pc/src/drivers/usb_host/pc/generated_dummies.c @@ -166,14 +166,6 @@ int dma_mmap_attrs(struct device * dev,struct vm_area_struct * vma,void * cpu_ad } -#include <linux/dmapool.h> - -void dma_pool_destroy(struct dma_pool * pool) -{ - lx_emul_trace_and_stop(__func__); -} - - #include <linux/printk.h> asmlinkage __visible void dump_stack(void) diff --git a/repos/pc/src/drivers/usb_host/pc/lx_emul.c b/repos/pc/src/drivers/usb_host/pc/lx_emul.c index ffe09af8fb..21b9949fb9 100644 --- a/repos/pc/src/drivers/usb_host/pc/lx_emul.c +++ b/repos/pc/src/drivers/usb_host/pc/lx_emul.c @@ -84,6 +84,12 @@ struct dma_pool * dma_pool_create(const char * name, } +void dma_pool_destroy(struct dma_pool * pool) +{ + kfree(pool); +} + + void dma_pool_free(struct dma_pool * pool,void * vaddr,dma_addr_t dma) { lx_emul_mem_free(vaddr);
