drm/radeon: allow to force hard GPU reset.

2016-05-02T17:08:54Z

In some cases, like when freezing for hibernation, we need to be able to force hard reset even if no engine are stuck. This patch add a bool option to current asic reset callback to allow to force hard reset on asic that supports it.

radeon: Deinline indirect register accessor functions

2015-05-28T18:52:40Z

This patch deinlines indirect register accessor functions. These functions perform two mmio accesses, framed by spin lock/unlock. Spin lock/unlock by itself takes more than 50 cycles in ideal case (if lock is exclusively cached on current CPU). With this .config: http://busybox.net/~vda/kernel_config, after uninlining these functions have sizes and callsite counts as follows: r600_uvd_ctx_rreg: 111 bytes, 4 callsites r600_uvd_ctx_wreg: 113 bytes, 5 callsites eg_pif_phy0_rreg: 106 bytes, 13 callsites eg_pif_phy0_wreg: 108 bytes, 13 callsites eg_pif_phy1_rreg: 107 bytes, 13 callsites eg_pif_phy1_wreg: 108 bytes, 13 callsites rv370_pcie_rreg: 111 bytes, 21 callsites rv370_pcie_wreg: 113 bytes, 24 callsites r600_rcu_rreg: 111 bytes, 16 callsites r600_rcu_wreg: 113 bytes, 25 callsites cik_didt_rreg: 106 bytes, 10 callsites cik_didt_wreg: 107 bytes, 10 callsites tn_smc_rreg: 106 bytes, 126 callsites tn_smc_wreg: 107 bytes, 116 callsites eg_cg_rreg: 107 bytes, 20 callsites eg_cg_wreg: 108 bytes, 52 callsites Functions r100_mm_rreg() and r100_mm_rreg() have a fast path and a locked (slow) path. This patch deinlines only slow path. r100_mm_rreg_slow: 78 bytes, 2083 callsites r100_mm_wreg_slow: 81 bytes, 3570 callsites Reduction in code size is more than 65,000 bytes: text data bss dec hex filename 85740176 22294680 20627456 128662312 7ab3b28 vmlinux.before 85674192 22294776 20627456 128598664 7aa4288 vmlinux Signed-off-by: Denys Vlasenko Cc: Christian König Cc: Alex Deucher Cc: linux-kernel@vger.kernel.org Signed-off-by: Alex Deucher

drm/radeon: Split off gart_get_page_entry ASIC hook from set_page_entry

2015-01-22T16:46:17Z

get_page_entry calculates the GART page table entry, which is just written to the GART page table by set_page_entry. This is a prerequisite for the following fix. Reviewed-by: Christian König Cc: stable@vger.kernel.org Signed-off-by: Michel Dänzer Signed-off-by: Alex Deucher

drm/radeon: use pointers instead of indexes for CS chunks

2014-12-03T23:26:53Z

Nobody is interested at which index the chunk is. What's needed is a pointer to the chunk. Remove unused chunk_id field as well. Signed-off-by: Christian König Signed-off-by: Alex Deucher

drm/radeon: Only flush HDP cache for indirect buffers from userspace

It isn't necessary for command streams generated by the kernel (at least not while we aren't storing ring or indirect buffers in VRAM). Signed-off-by: Michel Dänzer Signed-off-by: Alex Deucher
